GRD (or Block) is not a proper stat, but rather a hidden one, which has a chance of completely neutralizing any attack on the unit. Only some demon classes have a native guard ability, though there are skills among them as well as items at the player's disposal that can raise GRD. Skills/Items that bestow this defensive ability last for a limited time and must be reapplied for continued benefit. Multi-hitting attacks are optimal for circumventing this rather nasty defensive stat. Skills that are unblockable will land without fail, ignoring GRD completely.
Like Riviera, Guard has a chance to completely block an attack, resulting in no damage inflicted. However, some enhancements were made to accommodate Gungnir's gameplay style. Close-range attacks can be guarded by the target; the rate is dependant on equipement such as weapons or shields. If an attack is Guarded, the target can even launch a retaliatory counter. Guard is affected by which direction the target is attacked from (Facing). The percentages are as follows:
- Face to face - 30%
- Either side - 20%
- From behind - 0% (None)
One must keep this in mind at all times during any strategy. Endeavor to minimize the chance of an unsuccessful attack as much as possible.
Quick Tip: Rapier attacks cannot be parried by the enemy's weapon; only shields can block them.
