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.
Upon taking lethal damage, enter resurrection for 2 seconds, and afterwards heal for 80% base health(+ 50% bonus health) and become a zombie, during which you gain ( 75% / 30%) decaying bonus movement speed, reduce outgoing damage by 33% and incoming damage by 40%, and take true damage equal to a percentage of the amount of health started with that increases every 0.25 seconds. (300 second cooldown).
Damaging an enemy with an attack or ability causes them to be struck with lightning, dealing 25 − 75 (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 (8 second cooldown).
The slow can stack from multiple sources, and the decay rate is decreased against ranged champions.
When a team kills their fourth Elemental Drake, they'll gain a powerful Dragon Soul from the dominant dragon (the one that transformed the Rift). Dragon Souls persist through death and last the remainder of the game.
