[Powers] Super-heated sandblast attack

[PK]

To keep it simple, I'd probably just go "corrosion incendiary." The damage from the heat can be subsumed into the overall corrosion damage, which (for the most part) has similar enough effects to burning that it works well. (Except for the actual burning part, of course, but that's what incendiary covers.)

Unfortunately, that doesn't really cover the knockback part of things. Trouble is, if you try to represent, say, a 3d attack by linking Crushing Attack 1d + Corrosion Attack 1d + Burning Attack 1d, you're actually nerfing yourself because all of those attacks have to penetrate armor separately. Thus, I'd stick to using Corrosion Attack (Incendiary, +10%) as your actual damage, and if you want knockback, link Crushing Attack (Double Knockback, +20%; No Wounding, +50%) to it. That way, you're only inflicting knockback with it, and DR isn't even a factor.

So here's a potential build for a 6d attack:

Corrosion Attack 6d (Incendiary, +10%; Link, +10%) [72] +
Crushing Attack 3d (Double Knockback, +20%; Link, +10%; No Wounding, -50%) [12]

84 points total. Does 6d cor inc with full knockback as if it were a crushing attack, too.
