A kill is the event of decreasing an enemy champion's health to zero while the enemy has no abilities or items to prevent death. Death may be prevented by certain effects, such as those granted by the item and friendly abilities like Zilean's Chrono Shift, or delayed by passive abilities like Anivia's Rebirth, Zac's Cell Division and Aatrox's Blood Well.
The last player to strike the target champion is awarded with the kill, and all contributors within the last 10 seconds are awarded with an assist. If the champion killed has any transferable buffs ( Crest of Insight or Crest of Cinders), the killer champion gains all of these buffs and the duration of each buff is reset. When a champion is killed, the player who scored the final hit receives gold (50-500g) (on Howling Abyss maximum gold for a kill exceeds 500g) and experience. To reduce the effectiveness of feeders and snowballing lanes, less gold is awarded when a champion has a lower level than the killers. Additionally, a champion with many consecutive deaths will award a significantly reduced bounty, eventually reaching a bounty floor of 50 gold, nearly the gold value of a minion. The bounty will reset to 300 if said champion kills an enemy champion, or resets more gradually with assists or farming (refer to Bounty values Notes below for details). In gameplay, kills may be sacrificed in favor of securing a map objective, or due to other situational circumstances, such as the low health champion retreating into high risk enemy territory.
If a champion dies and hasn't been damaged or debuffed by another champion in the last 13 seconds, they are executed. Otherwise, the kill is awarded to the enemy champion who last dealt damage. Executions are caused by a turret, minion, or monster. An execution offers no gold but still grants experience to nearby champions on the opposite team when it is caused by a turret or minion.
In some cases it could be strategically advantageous for a player to purposefully be executed as an alternative to dying from an enemy champion; in doing so, the enemy receives no gold. Doing this on ARAM allows you to visit the shop without granting kills to the enemy team.
Note that executions do not end your killing spree.
The act of killing several champions within 10 seconds of each other (30 seconds to Penta Kill after a Quadra Kill if no enemy respawns). The following comments are shown: "Summoner" has slain "(slain name) Summoner" for a [...]!'

An ace is defined as killing the last living champion of the enemy team. Scoring an ace is far easier than scoring a pentakill, since the only requisite is for the entire allied team to kill the enemy team, rather than one person killing the entire enemy team. There is no gold bonus associated with aces.
The standard gain per kill is 300 gold. Every kill (in a row) by a champion increases their value (the reward gained for killing that champion) by 16.5%, up to a maximum of 500 gold. Each death (in a row) of a champion reduces its value, by 8.5% for the first death and 20% for every death afterwards, to a minimum of 50 gold. The bounty will reset to 300 if said champion kills an enemy champion, or resets more gradually with assists. Assists remove one stage of the death penalty each (if a champion was on his third death (220 gold), an assist would raise the value to that of two deaths (275 gold)). Every kill a champion achieves without dying (called a killing spree) increases that champion's bounty to a maximum of 500 gold as stated before. The gold bounty is not reset when the champion is executed without any enemy champion contributing to it. Being on a killing spree only affects the gold gained upon your death. First Blood (the first kill of the match) gives an additional 100 gold (400 total) beyond the basic amount for the kill.
|First Blood: +100 gold|
|1st kill: 300 gold||1st death: 300 gold|
|2nd kill: 350 gold||2nd death: 275 gold|
|3rd kill: 408 gold (Killing spree)||3rd death: 220 gold|
|4th kill: 475 gold (Rampage)||4th death: 176 gold|
|5th kill: 500 gold (Unstoppable)||5th death: 141 gold|
|6th kill: 500 gold (Dominating)||6th death: 112 gold|
|7th kill: 500 gold (Godlike)||7th death: 90 gold|
|8th kill: 500 gold (Legendary)||8th death: 72 gold|
|9+ kills: 500 gold (Legendary)||9th death: 58 gold|
- That gold values will continue to drop past the 9th death, eventually stopping at 50 gold. Also, with lower killing spree bounty cap and increased bounty gain, there is no additional gold for a shut down beyond the 5th kill.
- Every 1000 gold earned from minions / monsters reduces the death spree by 1 death.
- Kills are worth 75% of the base reward during the first 2 minutes of the game, scaling to 100% at 4 minutes. The bonus 100 gold gained from First Blood is not affected by this penalty
