Say I'm playing a figure with Vault who attacks (successfully) an opposing figure and rolls doubles causing Knockback... do I resolve my movement *before* the opposing figure takes KB, or after?

I would think the feat resolves before, but I can't be sure. THX!

So, you make the close combat action, deal damage if needed, then apply knockback (again, if needed): the close combat action is now resolved, and then you can use Vault.

i would think u would finish what your doing first then knockback..

so, you can follow them while they knockback? Sweet money.

According to these threads, you can indeed:

Man that makes for a funny visual, especially if Colossal Boy has Vault...
