            IDEA: Enraged Behaviour
            Lexy will teleport near a player and unleash every ability he has in a frantic assault - taking 5% of his max health every second while in this state - while becoming invulnerable to player damage.
            His damage will be multiplied to the power of 1000 - no player is expected to survive this. If they do, Lexy drops a dev set and a unique weapon (TBD).
            This will last until he dies.
