Raid Shadow Legends – Increase Damage based on Enemy MAX HP is one of, if not the strongest abilities in Raid Shadow Legends. These champions are able to do damage based on the health pool of the enemy. This is generally a boss killer with all bosses scaling with very high health as the game moves on to higher level dungeons and content. These champions should be built with his crit rate and critical damage! Be aware the Clan Boss wont scale correctly with this skill, it is best not used there as you move towards Nightmare Clanboss and up!
