剛毅 隨機單中：大混戰 combos

Endless tank-heal + damage. Take HP and regen runes.

Since Conqueror heals at full HP too, Yuumi attached to a teammate constantly procs Conqueror damage on enemies — need an ally that can hold ground. CoD Yuumi stacks HP — regular support items are useless; Moonstone doubles a heal into two heals, mandatory.
