When applied to a non-Damage effect, this extra causes it to inflict knockback like a Damage effect.
This is best suited to attack effects, naturally, although the GM should adjudicate applications of the modifier.
I'd lean towards the "fail the (initial) save by 5 or more."rgordona said:I looked this up in UP last night but still have some questions:
Knockback only applies on Dammage effects if the result is stun or worse. How does that translate to non-dammage effects. (eg Aditory Dazzle) does the Knockback come in if the reflex save is failed, or is it only if the save is failed by 5 or more, (as for a stun result)?
Not necessarily -- at a certain point the Action Flaw becomes the Action Drawback, and some situations are better handled as a Power Loss rather than Limited. If "No Knockback" isn't limiting enough to be a Flaw (and I would agree on that), we can certainly rule that it's a Drawback.rgordona said:I also have slight concerns that if Knockback is an extra then "No Knockback" would be a flaw on dammage effects (by symetry), so "Blast - No Knockback" would only be 1pp/rank, and that does not sound right to me.
