Hehe, thanks for the info. But, i don't need it, i knew that info for a long time ago. Allmighty is tenbu right?

Keep in mind it's an additional layer. So these add onto your character abilities and weapon elements.

Which means you can destroy things with little effort (Almighty) or have a super tank (Evasion).

Yeah, Tenbu(Almighty)very powerful. Cuz Tenbu, Lu Bu become my fav character. Lu Bu, Tadakatsu, and Keiji becoming my fav team.

I like the look of verity too, true musou being available regardless of life gauge status, that reminds me of the item in DW5 you could get which had the same effect. From what I've seen of it, I think i prefer this system to the old one.

I don't like that weapon ability. Tenbu my fav weapon ability. And Team Musou and Jump Cancel.
