Need help building power: Alternate Blows

[Anders]

From Celtic Myth:

In combat, alternate blows wound or heal you. The first hit does normal damage; the second hit heals that amount of damage. The third blow harms, the fourth heals, and so on. The advantage takes up where it left off at the end of the last combat.

There are a couple of ways to do this - one way is to DR (Absorption)... but that only heals half the amount done on every other blow. The other is some kind of Extreme Regeneration that activates every other blow and heals up to 10 HP per second. Both fall somewhat short of the original ability, and I suppose I could just port it over "as is" (for a cost of 75 points, which seems fair). Thoughts?

Maybe taking the damage as a point value and applying Cosmic to that at some level? I did something like that in Powers: The Weird, though I was applying it to an illusion ability, which may be easier to rationalize having that effect.

Apply the DR (Absorption) to all the blows, so that it charges on each hit. Then, the DR will have soaked enough points over two hits to fully heal the second hit. Since the first hit is supposed to hurt, you'll want a limitation for "Only Absorbs on odd-numbered hits, but lets the injury through". Sounds about -30%-ish, off the top of my head.

Or you could call it an Enhancement to double healing, plus the Limitation to only apply to even-numbered blows.

This advantage protects absolutely from 50% of attacks, while providing healing exactly equal to the other 50%. That could be a ridiculous amount of healing with extra hp, Unkillable, high HT, etc... and high incoming damage, and the infinitely effective defense for 50% of attacks isn't bad either.

That would be really expensive to simulate in 4E. Put some caps or limits on it and it will be much cheaper. If this advantage protected from 75% of the damage of every other attack, that sounds like IT:DR 4 with -50% for accessibility for 50 character points. You could then build a healing effect with the other 25 points, again with a -50% accessibility limitation.

Capping with DR instead of IT:DR and using absorbing as suggested would make the ability even more straightforward.

[Anders]

I'm thinking about making this IT: DR (2) with a Cosmic enhancement of some sort that changes it from affecting half the damage on each hit to affecting all the damage on half the hits. Maybe a +100% enhancement, since it can be gamed rather easily.

That looks like a better bet to me.

And maybe then just skip the part about healing. Doing that would be so expensive - we're talking 200 points or more to heal 12 points of damage per attack...

I'd go for DR with -100% doesn't protect and +80% absorption, healing only, and then either a limitation for every other attack, or half the value and use it every other attack, but then you can lose potential healing as you lose your absorption points. That makes the healing half pretty cheap.

Actually, if you have injury tolerance (2) across the board it means that the absorbtion DR actually heals 100% of the damage by default.

Can the system be gamed by both sides? as in having your buddy do an all out attack with a sledge hammer on a healing cycle?

Yep. My guess is that we're looking at a +300% modification here...
