Advantaged advantages

[Vestnik]

Can somebody help me with some math?

 

I'm building a Human-Torch-like character (actually a pyrokinetic whose powers give her the form of a flaming angel for psychological reasons, i.e., she thinks her powers come from god). I want to Harden her Force Field, but only the ED part and only against Fire/Heat. This is hairy mathwise because the power itself is in an EC, so I'm trying to buy the Hardened as a Naked Advantage outside the EC. The math is bugging me out.

 

Here's what I have so far:

 

Shroud of Righteous Flame (in the EC):

 

15 PD 18 ED Force Field, Costs END Only to Activate (+1/4) (41 Active Points), Not Underwater (-1/4), IAF (Rosary; -1/2) END: 3

Then, outside the EC, I have:

Hardened (+1/4) for 18 ED Force Field, Costs END Only to Activate (+1/4) (x Active Points), Not Underwater (-1/4), Only vs. Heat/Flame (-1/2), IAF (Rosary; -1/2) (Real Cost Unknown)

Normally if I just bought this as part of the Power, the Costs END Only to Activate advantage would be based on the cost of the 18 ED Force Field, but as written up here it would be based on the cost of the Hardened advantage. Is this right?

My head hurts.

OK...

 

The way I'd do it is to keep the whole thing in the EC, and do the advantage/disadvantage calculations keeping all fractions til the end (in order to prevent rounding abuse)

 

With all advantages, the power breaks out like this :

 

18.75 points for the PD (15*1.25)

22.5 points for the ED (18*1.25)

4.5 points for the hardening on the ED ((18*1.5)-(18*1.25))

 

Total = 46.25 = 46 Active points

 

Now apply the EC savings by the following method in order to make the EC reduction happen across all sub-parts of the power in the proper proportion : Subtract AP*EC/46 from each AP to get the post EC points:

 

With a 23 point EC :

 

18.75 - (18.75 * 23/46) = 9.375 for the PD portion

22.5 - (22.5 * 23/46) = 11.25 for the ED portion

4.5 - (4.5 * 23/46) = 2.25 for the ED Hardening portion

 

Then apply the disads :

 

9.375/1.75 = 5.35

11.25/1.75 = 6.71

2.25/2.25 = 1

 

5.35+6.71+1 = 13.01 = 13.

 

Your slot cost is 13 real points.

 

 

If you have only a 20 point EC, then subtract AP*20/46 instead of AP*23/46 in the middle step.

 

18.75 - (18.75*20/46) = 10.6 for the PD portion

22.5 - (22.5 * 20/46) = 12.72 for the ED portion

4.5 - (4.5 * 20/46) = 2.54 for the ED Hardening portion

 

Apply disads :

10.6/1.75 = 6.06

12.72/1.75 = 7.27

2.54/2.25 = 1.13

 

Total = 14.46 = 14 real points for the slot.

Wow, thanks for all the math.

 

What about the Only vs. Heat/Flame on the Hardened? Or is it in there somewhere and I just don't see it?

 

EDIT: ah yes you did -- I see. Thanks. I have to look at this a bit -- I am not big on numbers.

One thing to remember if you're going the Naked Advantage route is that Naked Power Advantages are Instant, not Constant, so you'd probably want Persistent or something.

Naked Advantage is not necessary.

 

Compound Power is the way to go.

 

20 Elemental Control, 40-point powers - END=

15 1) Shroud of Righteous Flame: (Total: 46 Active Cost, 26 Real Cost) Force Field (15 PD), Costs END Only To Activate (+1/4) (19 Active Points); IAF (Rosary; -1/2), Limited Power Not Underwater (-1/4) (Real Cost: 11) plus Force Field (18 ED), Costs END Only To Activate (+1/4), Hardened (+1/4) (27 Active Points); IAF (Rosary; -1/2), Limited Power Not Underwater (-1/4) (Real Cost: 15) - END=3

That construction misses the hardening only being vs fire damage.

Yes, but building the Hardened correctly (with Continuous) via a Limited Naked Advantage ends up being more expensive.

 

20 Elemental Control, 40-point powers

12 1) Force Field (15 PD/18 ED), Costs END Only To Activate (+1/4) (41 Active Points); IAF (Rosary; -1/2), Limited Power Not Underwater (-1/4) - END=3

 

4 Hardened (+1/4) for up to 18 Active Points of Force Field (18 ED), Costs END Only To Activate (+1/4), Continuous (+1) (9 Active Points); Limited Power Only vs. Heat/Flame (-1/2), IAF (Rosary; -1/2), Limited Power Not Underwater (-1/4) - END=1
