Nexus Clash

Child Skill of Way of Lightning. When Way of Lightning is activated, grants supplemental piercing damage to a firearm attack equal to the base damage of the gun, at the cost of 1 MP and double the ammunition per attack.

Would agree ES could use some ability to build extra damage
Would love if they were given more weapon tree choices, though, rather than "great at HtH/guns, good-ish at everything else"
