Critical Drain

Critical Drain is the fifth skill in 's Prudence skill branch. It heals him for 2% of his max when he lands a critical hit.

Overview
Entire strategies revolve around this skill. For Dunban, it is typically combined with 's guaranteed crits to heal significant amounts of HP over several seconds. For Seven, it is combined with the Ultimate Counter and Critical Combo skills (which also provide more crits). Other characters can work with these skills as well, but the costs are immense; Critical Drain is 50 coins, and the others are even more. As a result, it's probably not worth linking if the player isn't going all-in with the strategy.
