I just find that iss, can use 2H magic blunt (like branch of the mother tree) with skills, even the steal mana works with 2hB (and the animations of the 4 attacks that the iss have, are unique) but its supposed that the skills, only work with duals, so...
it's ok to use 2HB? it's a xploit or bugg if i do it?
Never heard of any restriction in skill usage depending on the equipped weapon. The reason Iss uses dual weapons was the mastery, but since other weapon masteries have been added...
Not to mention that there are Isses that use sword+shield combo (never seen them, but it's a viable build).
It's just the skill descriptions that are STILL wrong (they are since GoD came out).
You can use your complete skill set while equipped with sword/blunt/2h sword/2h blunt/dual sword/dual blunt. We only had mastery (+p.atk/atk speed/phys stance trigger parts) for dual weapons, but now we have full benefits with all 6 types.
So go ahead and use your staff if that floats your boat :p .
