How Do I...? Nerve Spasm/Muscle Twitch

[Black Rose]

Partly to let me keep track of my own questions, and to get answers.

 

Okay! I'm trying to figure out how to simulate this effect: I can make one target at a time suffer a momentary spasm or twitch. Most of you know what that looks like -- briefly lose your grip on something and fumble for it, stumble as you're walking along a normal path, and so on. Voluntary muscles only -- no stopping someone's heart. Anything that can be recovered from in about a second or so (a little more if you tripped and fell). The important thing is that I activate it, you "twitch", and we're done; if I want you to keep having problems, I must repeatedly do this to you (so no Constant effect). 

 

Now, thanks to writing this out, I'm starting to think Change Environment with Varying Combat Effects, that way I can effectively "inflict" a roll for what I'm trying to do (mostly DEX penalties I'm thinking, but also Running or Leaping penalties as needed). But there might be a better way I'm not seeing. Anyone?

 

TIA

The change environment looks like the best way.  The only thing I would add would be a small NND for the pain.

I think the best way to approach this would be would some type of Ranged Martial Art.

 

If I understand you you only want to cause item drops(Disarm), falls(Shove), distract(Flash) or hinder(Grab/Entangle). Strikes to various nerve clusters around the targets body would be the SFX just as in your OP.

Another option is Mind Control Based On CON, Invisible Power Effects, Limited Control (Only To Cause "Twitch" Effects). Prehaps even Line Of Sight range on that also.
