Caster's NP sacrifice the servant in front of him (Ally) to throw a powerful (Art type) AOE damage. In a nutshell it's Arash but you sacrifice someone else.

1st skill is target taunt on ally and decrease crit damage for all enemies. 2nd is Waver skill (https://fategrandorder.fandom.com/wiki/Advice_of_the_Strategist ) and 3rd is Buster UP on a target (If it's a berserker gives max HP and also critical damage)
