@AlphaZero you can improve the fragile caster with the warrior health, it improves the survivability of the DD and reduced the one from the tank, while the healer could heal all of them at the same time
@Samael If I were in a game and had this skill and can control what I summon, I definitely have a bunch of footsoldiers, and one beefy unit, like an undead dragon or something akin to that, if he does that combination those skeletons ain't dying any time soon, the dragon can tank the hits for them with its large health pool, then just have undead healers healing the dragon during the fight
