Attack Plus

Attack Plus is a gem effect in Xenoblade Chronicles. It increases the maximum damage stat of a weapon, up to 999.

Overview
Attack Plus widens the range of a weapon's possible damage. Unfortunately, due to the damage range glitch (damage can only reach minimum+99), this has no effect if the weapon already has a wide range. gems must be used to raise the minimum before raising the maxiimum does anything, making Attack Plus the significantly less useful of the two.
