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. Multiple buffs based on each dragon's element can be had. However, two elemental drakes will appear only once on the map, and one will not appear at all, so in a given game only one element can stack. These buffs are permanent and are granted to the entire team of the player who killed the dragon.
The Dragon Soul is a powerful team-wide neutral buff granted by the Dragon. It is available only on Summoner's Rift.
Slaying four elemental dragons will grant the soul of the dominating element after the rift changes.
Aspect of the Dragon is a temporary team-wide neutral buff granted by the Elder Dragon, which spawns after a team has slain 4 elemental drakes. It is available only on Summoner's Rift.
The buff is lost upon death.
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.
