Raid Shadow Legends – Block Active Skills is one of the strongest debuffs in Raid Shadow Legends. This will stop the enemies from using their Active abilities with cooldowns forcing them to default to using their A1 skill that are generally weaker. This skill is particularly strong in Arena, Faction Wars, and Doom Tower against waves of enemies however it will not work against bosses! A new debuff was introduced in Patch 4.20 – Block Passive Skills which blocks an enemy from using their passive skills.
