Dragon Slayer is a team-wide stacking neutral buff granted by the Dragon. It is available only on Summoner's Rift.

Slaying a dragon will grant a buff based on the element of the dragon slain; that buff can stack up to four times for a given element, and a team can possess more than one type of buff. However, only three types of elemental drakes will spawn on the map, due to the first two drakes consisting of two elemental types and all drakes thereafter spawning as the elemental type dependent on the element that dominates the rift. This means that in a given game, only the buff granted by the rift-dominant element can be stacked. These buffs are permanent and are granted to the entire team of the player who killed the dragon.

Elemental Dragons hold an Ancient Grudge for enemies who have slain their kin; they gain 20% bonus damage and 7% damage reduction against champions per stack of Dragon Slayer they have, up to 80% bonus damage and 28% damage reduction at 4 stacks.

Edit Cloud Dragon Soul Gain  20% bonus movement speed, increased to 60% for 6 seconds after casting your ultimate ability (30 second cooldown).

Edit Hextech Dragon Soul Dealing damage to an enemy with basic attacks or ability damage causes them to be struck with electricity, dealing 25 − 50 (based on level) bonus true damage and slowing them by ( 45% / 35%) (+ 3% per 100 bonus AD) (+ 1% per 100 AP) (+ 0.5% per 100 bonus health) decaying over 2 seconds, while chaining the effect to up to 3 enemies near the primary target.

Aspect of the DragonEdit
Description
Damaging enemies inflicts them with a burn that deals them 75 − 225 (based on minutes) true damage over 2.25 seconds, with the first tick occurring after 0.25 seconds and the others after 1 second each. Each tick of the burn deals 25 − 75 (based on minutes) true damage. This effect does not trigger from its own damage. Additionally, gain Elder Immolation. Elder Immolation: Damaging an enemy champion while they are below 20% of their maximum health and Aspect of the Dragon's buff is active blasts the target with dragon fire after a 0.5-second delay, executing them by dealing true damage equal to 100% of their current health. This effect cannot occur on the same target more than once every 2 seconds from any of Aspect of the Dragon's buff holders.
Elder Immolation's execute is negated if the target is invulnerable or has a minimum health threshold. Elder Immolation can trigger against enemies even if they are untargetable.

Notes

• Infernal Might's ability power multiplier stacks stacks additively with other sources of % ability power.
  • The Total attack damage multiplier stacks additively with other sources of % Total attack damage and stacks multiplicatively with sources of % Bonus attack damage.
• Transforming champions activate Cloud Dragon Soul's bonus movement speed upon transforming if they do not have an ultimate ability like Gnar.
• Cloud Dragon Soul's bonus movement speed is special cased on Udyr to activate on any of his Bridge Between-empowered spell casts.
• Hextech Dragon Soul, Infernal Dragon Soul, and Aspect of the Dragon's burn all deal default damage, and thus they will not trigger spell effects.
• Against non-champions, Ocean Dragon Soul heals for 48 (+ 10.8% bonus AD) (+ 6.75% AP) (+ 2.7% bonus health) and restores 24 (+ 1.05% maximum mana) mana over 4 seconds.

Trivia

• Ultimate Spellbook released with a unique Ruined Dragon using Mordekaiser's dragon from Children of the Grave during the 2021 Sentinels of Light Event. It was then supplanted by Hextech Drake & Chemtech Drake in V11.23 during the RiotX Arcane event. It granted a dragon soul similar to Chemtech Drake.
• Before patch V11.23, Cloudbringer's Grace's ultimate ability haste stacked additively with other sources of ultimate ability haste, and multiplicatively with regular ability haste.
  • For Shyvana, Cloudbringer's Grace instead granted her 10 / 23.33 / 36.67 / 50% (based on stacks) increased Fury generation.
  • For Udyr, Cloudbringer's Grace granted him 6 / 12 / 18 / 24 (based on stacks) haste on his global cooldown between stance swaps.
• Until patch V9.23 each component of Dragon Slayer had a passive name and an alternate name, related to the drake:
  • Cloud Drake's was Stratus Walk and Dragon's Flight.
  • Infernal Drake's was Infernal Tribute and Dragon's Might.
  • Ocean Drake's was Heart of Oceans and Dragon's Dominance.
  • Mountain Drake's was Earthen Arms and Dragon's Wrath.
