League of Legends patch 14.15 notes are now live and along with the changes to Summoner’s Rift, Swarm will also be receiving massive balance updates. Boss Enrages will see a lot of tweaks with many champions and items seeing a fair bit of buffs and nerfs heading their way.
Below is a list of all the changes that are heading to Swarm in League of patch 14.15.
League of Legends patch 14.15 Swarm updates and balance changes

1) Boss Enrages
- Old Enrage: After 5 minutes bosses would enrage (invisibly) causing all damage to (invisibly) one-shot players. After 7 minutes bosses would (invisibly) kill all players who somehow managed to survive.
- New Enrage: After 5 minutes bosses will visibly enrage and start to glow red. For the next 30 seconds they deal 20% increased damage, after which they will unleash a nova that kills all players. Enrage timers on
- Aatrox reset when he transitions to his second phase.
2) Buffs and nerfs
Bosses
- Aatrox has realized that some COWARDLY champions have found areas where his flying swords cannot reach during phase two. NO LONGER.
- Briar has been working out for her boss fight. Everything deals more damage.
- Rek’sai no longer shotguns champions with missiles while knocking them up, resulting in unclear “funshots”
- Decreased Rek’Sai’s missile hitbox to match the visuals.
Generic champ things
- Untargetable champions can now res allies and pickup cards, health, bombs, and vacuums.

3) Champion updates
Briar
