A few questions about two-weapon rend...

[Ari-chan]

Hi! As a relatively new GM in Pathfinder, I had few questions about some of the leanings and interpretations of two-weapon rend.

1) On the chance that both hits critical, does the rend damage get multiplied as well due to it being a physical number or is it treated like the burst weapon effect critical damage?

2) How does this work with different weapon types? I'm having some difficulty seeing how this might work.

Thanks in advance for any help you can give. XD

1) No it is not multiplied.
2) doesn't matter, as long as both primary and off hand hit, the rend damage happens. Its damage die and bonus are fixed.

Thank you. Sorry for taking so long to get back to you. XD
