I assume it would only be continuing spells.
 
You could make it a limitation on magic in your campaign. A sorcerer must make a skill vs. skill roll to take over another's spell. 
 
Maybe you could only try to take over a spell you know; or maybe in the same school of magic, if you're doing schools of magic.

For those who aren't aware, Jennell Jaquays was known as Paul Jaquays then, and yes, it was denial; I asked her about it.

You might be interested in a similar VPP power I developed for my Young Scratch character:
 
Through Me The Way Is To The City Dolent: Extra-Dimensional Movement (single location in the Netherworld), Area Of Effect (personal Surface—Damage Shield; +¼), Constant (+½), Usable As Attack (does not work on targets of good character or who have holy objects upon their person; +1¼) (60 Active Points); Gestures (both hands; -½), Incantations (-¼), No Range (-½). Total cost: 27 points.
 
I set up the exceptions conditions on the UAA so that it wouldn't work on anyone who wasn't going to end up there eventually anyway.

I have some strong recommendations.  
 
Use the APG's.  Specifically, for: 
Social Combat Possession Extradimensional Space The Ghostbusters will likely never have a reason to engage in physical combat with other humans.  They will need to engage with them socially for finding information, getting funding, avoiding governmental audits (IRS, EPA, the Nuclear Regulatory Commission...), managing their reputations.  
 
I wouldn't try to "build the spoon" with proton packs and other equipment.  Ghostbusters are Heroic level PCs, with no special abilities of their own, so proton packs can have a basic writeup of what they do.  Drain, 1d6, all ghostly Powers, one at a time, recovers per month.  They're big and bulky and need to be recharged back at base after heavy usage (say, an hour).  The "jobber" ghosts (the one-and-done mook types, the spud, Slimer, etc.), all of their Powers are built with Unified Power, so they drop hard and fast when proton beams are applied.  If they need to recover from them, they can buy Regeneration, all ghostly Powers, one at a time, however much they need.  Any Desolidification they have automatically has proton beams as the SFX that it doesn't protect against.  The mid-range, Shubs and Zuuls, demonic dog critters, have enough Power Defense that they can ignore a proton beam, and Gozer and the Traveller are boss-level entities that need a lot of research to defeat, and likely crossing the streams.  
 
Speaking of, crossing the streams will never happen by accident; technobabble here, but basically, proton packs put out a stream of positively charged particles.  Take two magnets, try to push the positively charged (north) poles together, and what happens?  They repel one another.  Crossing the streams is something the Ghostbusters have to do on purpose, and they have to fight the packs to get them to do that.  And when they do?  Each pack provides 25 Active Points worth of a Variable Power Pool that the GM gets to use for whatever they want.  If there's an extradimensional cross-rip, they'll typically create some kind of explosion to close that.  If there's not one, then the GM gets a minimum of 50 Active Points worth of whatever.  
 

I was NOT the GM for the misadventure I am about to relate, but it's the worst example I know of.
 
D&D.  The DM's wife was a writer and wanted to see what this D&D thing was all about, so we set up a little party for a campaign.
 
* Elven Rogue (me), sailor by trade, good with knots.
 
* Dwarf fighter, strong and tough.
 
* Halfling of some flavor.
 
* Halfling bard of some sort (DM's wife).
 
So the absolute opening scene of the campaign:  we open a door and are confronted by a chasm with a river of lava in the bottom.  We must cross to continue.
 
My sailor Elf with rope and high agility manages to get a grapnel across and shimmies over.  We have to make dex rolls, which frankly not many first-level characters are good at. The generic halfling goes over next.  
 
Then the DM's wife.  She rolls a 1.
 
Down she plunges toward searing molten lava! 
 
Signaling to our doughty Dwarf, still on the starting side,  to anchor the rope around his waist and brace himself, my Elf leaps into the abyss, swinging down to save his companion, the DM's wife, and the entire campaign.
 
A perfect roll!  The elf snatches her from certain death.  Both their falls are checked momentarily by the Dwarf's brawn as he performs a belay.
 
He rolls a 1, and is yanked off the ledge. You knew this was coming, didn't you?
 
All 3 of us plunge into fiery death.
 
The halfling is the sole survivor, left alone in the hostile side of the chasm with no rope and no way home.
 
The DM's wife, who, as a published author, is used to having *total control* of plot and characters all to herself, storms out of the room without a word.
 
Campaign *finis*.  She never wanted to try again.

I once ended a session by having the PCs find a letter that contained vital information.  They had spent the whole session looking for it, felt good they had found it, and one Player transcribed the letter as they were certain it had more clues than were obvious.

The next session they formed a plan to act on their new information & I had a NPC interject to remind them of an important thing they were overlooking (I didn't want to waste a session with them going down a blind alley).  They insisted that *wasn't* info that they had.  I insisted it was in the letter they had just worked so hard to get.  The players all looked at me in silence & the one who had transcribed that letter held up her notebook page & proved that info *wasn't* among the info they had gotten from the letter last session.
 
Knowing I had screwed up & left out a vital point, I (rather lamely) had the NPC declare there was "a hidden fold" in the letter that contained the information.
 
The Players all laughed for about 10 min at my weak save & from that point on if I ever tacked something on to an ongoing info dump someone would mention that "there must have been a fold".
 
This has been a running joke now for 25 years.  I married one of them.  The woman with the notebook was our Maid of Honor.  In the years since I've gotten christmas cards that say "Merry Christmas! and a >obvious fold in the card< "Happy New Year".  I texted my wife 4 things to pick up at the store a couple weeks ago, then remembered something else 10 min later & got a text back "was there a fold?"
 
I try to take it with good humor......

My funniest one --- Players fought a team of villains who had a female mentalist as a member. Later, I forgot about that and rolled the team out again with the same mentalist as a male. The group said "wait a minute -- last time that was a woman!" I disagreed and told them they were mistaken, which they completely proved me wrong with their notes. After that, anytime I threw a mentalist at them, it came up --- are you SURE this is a man/woman?
 
They got a lot of mileage out of that one.

4) I create a new villain who will be a archenemy for the group. The villain is carefully created to be a match for the team. Two sessions later, I get the strong feeling the players don't like him so I quietly move away from any archenemy. On the other hand, a one-shot npc becomes loved by the players. The NPC's name? Edna Mode.    Really, I'm happy this happened and she's become a major NPC for any hero who needs a justification for supergear.
 
5) (Early GMing mistake here...)  Trying to create an atmosphere for the characters, which the players just aren't in the mood for. Bad timing.
 
6) Trying to do a serious episode on a Friday evening, when everyone's had a long day and isn't in the mood for anything serious. I remember someone saying, "I'm not in the mood for something serious. Do we have anything light-hearted?"  Instantaneous episode creation is a test of any GM... but I did it.

I have finally gotten around to seeing No Way Home. It was excellent. Brilliant writing as usual, and Tom Holland and Zendaya are very good at their jobs. 

When we first meet Thor in his debut movie, he's been living what amounts to an extended childhood. Over the 1,500 years of his life he's always been privileged, never known failure, never had to suffer the consequences of his actions. (We've learned that humans can live that way for at least seven decades.)   He defined himself as a warrior, a prince, a hero, but in the end he failed at all those things. Over the span of a decade he lost his power (albeit temporarily), lost his lover, lost his whole family, lost all his closest friends, lost his home, and lost the weapon that was like a part of him. He failed to protect his people, and lost most of them. He failed to save half the people in the entire universe. That so overwhelmed him that he lost the will to do anything but eat and drink and play video games, becoming a mental and physical mockery of who he was.
 
I don't care how long you've lived, if all that doesn't prompt deep soul searching, I don't know what could.

Aside from any Ukrainians, Ukrainian expats living in other countries, people with family or friends in Ukraine or people of Ukrainian descent; anyone who has been following the situation closely and has respect and empathy for Ukraine's struggles and what its people have already suffered.
 
On the other side of the coin, any Russian expats, people with Russian friends or other ties to Russia, who may already feel that Russians are being unfairly stigmatized for the actions of their government, and for whom using the RD characters in this way could be rubbing salt in the wound.

They (the leadership) should take the name and run with it. They don't have bases, they have Haunts. They are not organized in "cells" but in Covens. There planned crimes are called "Hexes". They don't have pets, they have Familiars. 
 
Do with it what you will.

So i not notice focus ... Adding OAF Sword would impact cost in favor of Constant version.
 
Killing Attack - Hand-To-Hand 2d6 (2 1/2d6 w/STR), Constant (+1/2) (45 Active Points); OAF (-1), 2 Continuing Charges lasting 5 Minutes each (-1/2), Conditional Power Power does not work in Uncommon Circumstances (Must Roll To Hit For Every Attack; -1/4) .. Real Cost: 16
 
Killing Attack - Hand-To-Hand 2d6 (2 1/2d6 w/STR), Time Limit (5 Minutes; +1) (60 Active Points); 2 Charges (-1 1/2), OAF (-1) ... Real Cost: 17
 
 

Did the comparisons:
 
Temporary Big Sword:  Killing Attack - Hand-To-Hand 2d6 (2d6+1 w/STR), Constant (+1/2) (45 Active Points); 2 Continuing Charges lasting 5 Minutes each (-1/2), Conditional Power Power does not work in Uncommon Circumstances (Must Roll To Hit For Every Attack; -1/4)  26
 
Temporary Big Sword: Killing Attack - Hand-To-Hand 2d6 (2d6+1 w/STR), Time Limit (5 Minutes; +1) (60 Active Points); 2 Charges (-1 1/2)  24
 
So Constant has a lower AP cost but (slightly) higher Real point cost than Time Limit.  I conclude that either works.  Would probably default to Time Limit, except for the caveat "Time Limit is generally intended for nonattack abilities" 🤔
 
Anyone else want to weigh in?

Just got back from finally seeing No Way Home at the movies. It was most excellent.

So I was re-reading 5E Champions.  In that book this tactic is called a "Sucker Attack".
 
I won't reproduce the text.  The technique is to get between two enemies and wait for one (or both) to attack.  The character must have a Held Action, then Dodges (Nightcrawler would of course bamf out).  Make the normal DEX vs. DEX roll to go first; if the dodger loses the first attacker's attack happens before the dodge (rather than the normal 'Abort to a defensive Action automatically goes off first', but this is an offensive use of Dodge and so seems reasonable).  If the dodger wins the contest, the attacker makes an Attack Roll using only OCV (no CSLs, maneuver bonuses, or suchlike) against the second attacker's DCV.
 
Aaron Allston had it figured out in 2002. 😁

The basic defense against UAA powers is not to get hit. The secondary defense depends on what power the advantage is attached to. Against Teleportation UAA it is the target having Teleportation or Extra Dimensional Movement.
 
One of my villains, Father Time, has a Teleportation UAA attack which is limited that it could only send targets to areas they have visited in the past. The defense for the attack is having whatever you decide is "Time Control" powers. Life Support: Reduce Aging can be it, as well as EDM Time Travel, a high SPD stat, or anything else with a Time Control/Time Travel special effect. 
 
Each UAA is unique and needs to be thought as what the special effect of the power is. Some UAA powers won't affect anyone with the same special effect as the power. Other UAA powers won't affect anyone with an opposite special effect as the power (water or ice vs fire for example).
 
In short, it is up to each game master to define the defense of each UAA power.

*BAMF*
"My eyes!"

Use Trigger.  If the Teleport is always accompanied by the Flash, put Linked on it as well.

There are halflings in my "Magozoic" D&D campaign because it's a D&D campaign. I treat them mostly as just small humans. I have had no reason to develop their cultures to any great degree, in part because no one has yet asked to play one.
 
There are multiple halfling ethnicities. Halflings native to the heartlands of the Plenary Empire are called Leptopoda ("Lightfoots" -- no Stout subrace because their poison resistance schtick overlaps too much with dwarves.) Your basic peaceful agrarian folk, living in smallish hill areas with subterranean homes. Probably the most notable feature is that their gods form a divine village rather than the divine royal family so common among human cultures. There's no King of the Gods, there's a Mayor of the Gods. Other gods have similarly homely roles: shepherdess, wise old granny, artisans, farmers. No warriors or other "hero" types. Myths emphasize quick thinking and good sense, and usually end with everyone sitting down to a good dinner in good humor. Many Leptopoda have moved into human cities and assimilate well.
 
The Laterculi ("Bricklings" -- not their name for themselves) come from arid western lands that used to be part of the Plenary Empire, where they built pueblo-like adobe villages in oases. A long history of attacks from desert raiders made them clannish and suspicious of outsiders. They did not assimilate particularly well. The chief result of their becoming part of the Plenary Empire was to generate a national consciousness that they, as a whole, didn't belong in it. They got their wish when the western provinces broke away in the chaos following Panopticon's War. Then the Sorathite zealots returned from their long exile in the far west, conquered the whole regions, and gave the Laterculi the same choice they gave everyone else: convert or die. Plenary cities now have ghettoes of Laterculi refugees who still show no interest in assimilating.
 
Distant lands have their own halfling cultures. The port city of Thalassene has a small enclave of halflings from Vohai. Vohinese halflings have dark brown skin and straight black hair, often worn long in elaborate braids. These equatorial halflings introduced the Plenary Empire both to choolate and curry (Vohai is a major source of spices). Every lunch counter in Thalassene now includes a curry booth. Everyone knows, though, that for the very best curry you have to know someone in Little Vohai.

Exactly, I’m not saying you should or shouldn’t have them. If you like elves, include them. If you want elves and don’t like Tolkien, change it. If you don’t like them don’t feel you must have them. My only caveat is that since this is a group endeavor how much of your personal taste of elves be a game breaker? Can you not compromise? So a GM and several players don’t like elves and you do. Can you not play another character that has some of the traits of an elf? Or as a GM, if you don’t like elves and a player likes them can you talk to the player and see what can be changed to allow an elf? I heard one guy (proudly) say that he doesn’t let any of his players play Wookiee unless they can sound like one. I questioned him on that. To me getting friends together to roll dice and play a game trumps many issues. If the players are having fun, I’m having fun.

I started making my elves for Champions instead of Fantasy Heroes.  My elves never evolved on earth but they instead evolved on their home dimension, which is known as Tír na nÓg.
 
For everyday spent in Tír na nÓg, a week passes on Earth.  Time lost on the dimension of the elves catches up with the traveler.  Non-natives who spend time in Tír na nÓg and then return to Earth instantly “catch up.”  A visitor who stays a long time in the dimension of the elves may die if “catching up” with Material Plane time takes them beyond their normal lifespan.
 
My elves come in only two types, those elves that don't have feathery wings and those that have feathery wings.
 
Elves' magic abilities are extremely high since they are the one who first discovered magic more than ten thousand years ago
 
I have thought that my elves are unable to metabolize iron.  I have also wanted my elves to have touch-contact weakness to iron.
 
One of my elves has large branching antlers.
