So I tried a conversion of Leech, from Champions, and it was okay...but last night I realized that I had used totally the wrong power. So let's try it with the actual rules, hey?
Leech (Frank Winston) — Transformed
|Stealth (+1), Underwater Combat (+1)|
And there I was trying to make Nullification cumulative and affect abilities, and heck, Energy Drain already does that.
And now Leech comes in at what, about 53 points? Reasonable for a rolled-up character. I'll have to try him out against someone. (Found an error. Fixed it, but now about 65 points. Not so reasonable.)
