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 , or delayed by passive abilities like , and .
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 ( 50-500) (on Howling Abyss maximum gold for a kill exceeds 500) 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, 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.

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.
Gold can be earned by killing or assisting in killing enemy champions. The gold gain is determined by how many kills the slain champion has recently accumulated (champions that have killed many enemies without dying are worth more gold).
- Gold bounty stages are formally classified into Bounty Tiers.
- A champion's bounty increases as he accumulate kills without dying, starting at 2 kills (tier 2).
- Shutdowns now reduced your current Bounty Tier by 3 changed rather than fully resetting it.
- Gold granted to the killer is 300 at all Bounty Tiers.
- Assist pool is 150 at all Bounty Tiers.
- Assist pool is shared evenly among all people who get an assist.
- Champions are worth global gold based on Bounty Tier. This is granted in full to all allied champions -- living or dead -- on top of the gold earned for killing/assisting.
Death sprees reduce the gold gained (kill/assist) from champions by a set amount based on their consecutive deaths without getting a single kill (starts to take effect once a champion has their Bounty Tier reduced to 0).
- 1st death: 300 (assist pool is 150)
- 2nd death: 274 (assist pool is 137)
- 3rd death: 220 (assist pool is 110)
