So we found that Amulet of mighty fist +3. It will be used by my half-dragon. He has 2 class levels as monks. He has STR 20.
(1) Is it true that the amulet increased his claw damage from 1d4+2 to 1d4+5?
(2) is it true that the amulet increases his unarmed (fist, knee...) attack damage from 1d6+5 to 1d6+8?
(3) is it also true that the amulet increases the damage while grappling using "damage your opponent" and also for the grapple checks itself?
