Interaction between Feral Mutagen and Handwraps of Mighty Blows

[Quintessentially Me]

Does the die increase from Feral Mutagen when you elect for the extra AC penalty stack with any die increase from a Striking rune on Handwraps of Mighty Blows?

[shroudb]

Striking runes from handwraps increase the number of dices.

Feral mutagen increases the die size

They do 2 completely different things, and yeah, they stack (it would be silly not to, it would make the ability completely worthless).

Sorry... I just smoothly read right past that. :)
