My 6th level Aldar, Cleric of Ligth, uses a Heavy Mace as her favourite weapon. While the stun that comes with the "normal" Fullstrike of the Heavy Mace is pretty awesome, there's times that you can't really stun an enemy (as is the case of Dragon-Blooded characters, for example, or any Divine Offspring).
In those cases, Bleed Damage is still an option. Can I choose what kind of fullstrike I do with my weapon? Or are concussive weapons limited to the Stun Fullstrike?
