Unleash your fury instantly. Dealing up to 157% weapon damage and increasing the critical hit chance of your next ability by 10%. If mutated fury is a critical hit then your next ability has a 100% critical hit chance.
Unlike the regular Fury, Mutated Fury is not a channelled ability, instead dealing a single hit for up to 157% weapon damage instead of three smaller hits; this is similar to cancelling Fury after the global cooldown after it has dealt two hits.
Additionally, Mutated Fury increases the player's critical hit chance of their next non-bleed ability by 10%, again similar to cancelling Fury after two hits. If Mutated Fury itself is a critical hit, the next non-bleed ability the player uses in the next 30 seconds, including Magic and Ranged abilities, has a 100% chance to be a critical hit. If the ability used is a combo attack, only the first hit will critically strike.
