League Patch 10.15 notes: New champ Lillia, Swain & Skarner buffs, more

Isaac McIntyre

The League of Legends 10.15 patch notes welcomed Lillia to the Rift while introducing extensive champion balance changes for players to dig through ahead of the July 22 update.

The spotlight for patch 10.15 is on Lillia. The dreamy jungler will be the 149th character to join the League of Legends roster this update.

Meanwhile characters like Swain and Skarner are getting a few overhauls in their ability kits, and is definitely something to keep an eye out when playing with or against them.

Swain is getting a big raft of buffs this League patch.

Lillia release date

Champion 149 is here. Lillia is now on the PBE, with the “dreamy” new jungler available for testing. The “mid-range skirmisher” features a lot of consistent DPS in her kit, as well as the infamous ‘sleep’ mechanic popularized by Zoe on her ultimate.

Lillia hails from Ionia, the spiritual heartland of Runeterra. Living among the trees in her “garden,” she doesn’t venture far, afraid of what’s beyond the scrub. Thankfully, she is set to venture onto the Rift in League Patch 10.15, however.

Want a little leg up on your ranked rivals straight off the bat with the Bashful Bloom? We’ve already got a dedicated Lillia guide for you to master champion 149, including which runes to take, what to build, and plenty more!

Lillia is being released in League Patch 10.15.

Skarner, Swain get hefty overhauls

Skarner received damage bonuses on his Q, as well as a tweaked mana cost. Riot says this should make him a “stronger damage threat against fighters and tanks.” The LoL devs are achieving this by super-charging his Q.

Swain, on the other hand, mainly had his cooldowns changed. His Vision of Empire (W) range also got a slight tweak and lower damage. Finally, the Master Tactician’s movement speed dropped following the patch.

“Swain balance target is to help both solo lanes and support players equally,” Yetter said on Twitter after unveiling the patch cycle’s planned changes. “[These changes should] skew him a bit better in high Elo, because he currently stomps in low [Elo].”

In non-champion changes, basic support item Spellthief’s Edge have been buffed. The mage-based default item, which eventually builds into Frostfang and Shard of True Ice, has fallen by the wayside to its tankier counterpart in Relic Shield.
