Raid Shadow Legends – Unkillable buff is one of the strongest buffs in Raid Shadow Legends mainly used to build teams that cannot be killed against Clan Boss or to help you progress through dungeon content. An Unkillable buff will prevent any champion from going below 1hp all the time it is active. This buff cannot be extended through any champions buff extension skills. It is possible to remove an Unkillable buff from your enemies or prevent it from even being applied. The strongest methods for this are cleanse buffs skills or block buff debuffs.
