Put a lot of the aforementioned abilities on most champs and they will sandbag a few of them. Vitality: creation on almost any champion is OPasf for its nora cost. Similarly void shield though less so depending on the ratio between HP/def/cost/etc.
in beta it works 1 time per turn and it dont heal anymore if i noticed correct and medal of valor will only work on melee range 1-2 but i can be wrong, it happends alot
