Yep, mana doesn't work for me either, haven't tested the others.
Looks like PISORF got super buffed, looks to be super useful in Naga City where the bosses are squished up together.
I just tested it and...
This change affects Half-Dragons too!
Setup: 10 base attack, with +10%. And 100% knockback.
Test: Hit a monster into another monster
Result: 19 damage = 11 base + 8 knockback
Therefore, hitting a monster does approximately 80% as much damage as a wall. 60% * .8 = 48%, so that that matches PISORF!
