Dirty Kick seems to be bugged

[harperfan7]

I'm doing some tests to see how high I can get my dirty kick damage.  The range on the quickslot says 432-741.  I have a high crit chance with regular attacks (50%), im getting opportunist, and I have monster slayer.  I'm attacking a stunned rathound.  It always says "opportunist" with each kick, and sometimes it says "critical hit", yet I never do more than 741.

Dirty Kick is a very unique ability where it's a unarmed attack, but it uses a separate unarmed "weapon" so to speak, so it is not subject to most modifiers of regular unarmed attack. I changed it a bit so it now takes into account the critical attack when calculating damage. Just keep in mind that the crit damage bonus is the 100% and not whatever your normal unarmed attack crit damage bonus is.
