TERROR OF THE DEEP — Always Active
  • Attuma has a 91.9% chance to start the fight with a personal Concussion Debuff. It is paused until he gains a personal Concussion from another ability.
  • Incoming Bleed Debuffs suffer 49.6% reduced potency.
  • Attuma’s rough skin can now also deal damage any time he strikes his Opponent. In addition, its damage is increased by 5.0% for each Bleed effect on either Champion.
ALWAYS ACTIVE
  • Attuma’s plans can make the best out of the worst situation, or the worst out of the best. All Ability Accuracy modification effects on him have their potencies reversed.
  • While one of Attuma’s personal abilities with a listed chance has over a 100% chance to trigger, the ability has a chance to trigger additional times. Each time, the chance is equal to the former chance -100%. This repeats until the ability fails due to chance.
  • Attuma’s rough Talokanil skin abrades his Opponents with a 25.0% chance to deal 22.0 Physical Damage when they strike him or his Block with a contact attack. Damage scales with Base Attack only.
  • Whenever an Opponent Evades Attuma while he has less than 1 Bar of Power, he has a 100.0% chance to instantly gain 15.0% of his Max Power and passively go Unstoppable for 1.5 seconds.
  • Attuma’s Base Regeneration Rate is 35.0% instead of the usual 100%. It cannot be lowered further.
HYDRATION — MAX STACKS: 20
  • The water in Attuma’s Special Attacks grants him stacks of Hydration, which are Passives that fall off one at a time over 8 seconds as Attuma dries out.
  • With every stack of Hydration, Attuma’s Attack Rating is increased by 6.0, and his Regeneration Rate is increased by 1.8%.
  • At -1 stacks of Hydration, Attuma becomes immune to Incinerate and gains a Precision Passive increasing his Critical Rating by by 50.0.
  • At -1 stacks of Hydration, Attuma becomes passively Unstoppable.
  • When he is inflicted with or immune to an Incinerate or Shock, Attuma loses 100.0 stack of Hydration, and Hydration falls off 30.0% faster while suffering from Coldsnap.
HEAVY ATTACKS
  • 100.0% chance for Attuma to attempt to Purify 1 non-damaging Debuff, excluding Concussions, and replace it with a Concussion Debuff, reducing Attuma’s Ability Accuracy by 50.0% for 25 seconds. If there are no eligible Debuffs, this ability consumes the oldest stack of Hydration instead.
  • This ability also triggers when Attuma is inflicted with a Stun or Infuriate Debuff.
SPECIAL ATTACK 1
  • 100.0% chance to gain 300.0 stacks of Hydration.
  • On activation, 120.0% chance to gain a True Accuracy Passive. These Passives last 10 seconds and fall off one at a time.
SPECIAL ATTACK 2
  • 200.0% chance to gain 200.0 stacks of Hydration.
  • Each hit has a 50.0% chance to grant Attuma a Cruelty Passive, increasing his Critical Damage Rating by 8.0 for 22 seconds. Can trigger though Block.
  • Triggering one of these Cruelties pauses Attuma’s existing personal Concussions for the Cruelty’s duration.
SPECIAL ATTACK 3
  • 110.0% chance to gain 500.0 stacks of Hydration.
  • 100.0% chance to inflict a Bleed Debuff on the Opponent, dealing 150.0 Direct Damage over 20 seconds.
  • When one of these Bleeds fails to apply due to an Immunity, instead inflict a Physical Vulnerability Debuff that reduces the Opponent’s Physical Resistance by -30.0 for 16 seconds.
