The full League of Legends 12.15 patch notes have been released by Riot lead designer, Phroxzon, detailing buffs to the entirety of the energy class of champions and nerfs to some of the more overpowered items. Phroxzon explains that the energy changes are to give those champions more flexibility in terms of consistent damage, rather than having to rely solely on bursting your opponent down.
League of Legends patch 12.15 notes
Below are the full League of Legends 12.15 patch notes, courtesy of lead designer Matt Leung-Harrison.
- Dream-Laden Bough (Passive): Monster damage cap 40-100 > 50-150 (based on level)
Lillia’s passive ability burns enemies and monsters every time she hits an ability on them. Giving her passive a damage increase should help with her clear, both early game and late. The faster you’re able to clear your camps gives you more free time to make plays around the map.
- Noxious Slipstream (Passive): Movespeed 20% > 25%
- Noxious Slipstream (Passive): Per-target cooldown 10s > 8s
- Insanity Potion (R): Bonus stats 20/60/100 > 30/65/100
Singed is getting faster, more often, and his ultimate now offers him more bonus stats. A joyous day for Singed mains for sure, a dark day for everyone else.
- Soaring Slam (R): Cooldown 110/95/80s > 90s at all ranks
- Soaring Slam (R): Range 600 > 800
- Soaring Slam (R): Dash speed up by 200
- Soaring Slam (R): Range growth by movement speed ratio 1.3 > 1.5
A lot of Rammus’ engage potential is gated around his ultimate. This change makes the jungler more effective early – being able to cast your R more often at the start of matches should help your team out massively.
- Shield of Daybreak (Q): Mana cost 45-65 > 35-65
- Solar Flare (R): CC duration 1.5s > 1.75s
Lowering Leona’s mana cost on her stun should help with the laning phase, being able to potentially lock your opponent down more often before having to retreat to the fountain.
- Death Sentence (Q): Cooldown 20-12 > 19-11
- Death Sentence (Q): Damage 80-240 > 100-260
A competent Thresh player is already a nightmare for any ADC, being able to save his lane partner while also locking you down is incredibly helpful for the entire team. Lowering the cooldown and increasing the damage on his main CC ability means that if you get caught by his scythe then you’re in a world of hurt.
- Electrical Surge (W): Cooldown 14-6s > 13-6s
- Electrical Surge (W): Damage 60-160 > 70-170
- Slicing Maelstrom (R): Ability power ratio 20% > 22.5%
Riot has said that Kennen’s energy usage was in a good place, so instead of buffing that, he is receiving a sizable increase in his damage output. The AP ratio increase, especially when full build, could see his ultimate doing some serious damage.
- Twilight Shroud (W): Energy refund/increase 80 > 100
Honestly, not the biggest buff to Akali with this change. Her shroud is vital for staying alive inside a foray, and getting a little more energy back for using it will mean you can output an extra ability during a fight – or clearing minion waves.
- Living Shadow (W): Ability mimic range 2000 > Infinity
- Shadow Slash (E): Energy cost 50 > 40
Seeing ‘infinity’ on anything can be alarming, but this change just means that Zed’s shadows will mimic his abilities from any range. The chances of him getting far enough away before the shadows expire for this to be worth much are low. Lowering the cost of one of his abilities means more opportunities to spam these in lane – a small win for Zed mains.
- Shadow Dash (E): Energy refund 30-40 > 30-50
This buff isn’t something that Shen players will see the benefit of until later in the match. Being able to restore more energy with this ability will enable a little more sustained damage during team fights.
- Recast energy spell cost: 30 > 25
Lowering the energy cost to cast your spells is vital for an energy champion, it enables more sustained fights and more consistent damage.
- Meditate (E): Cooldown 18/17/16/15/14s > 18s at all ranks
A small but potentially significant change to Master Yi’s ability to stay in and around fights indefinitely at the late game. Being able to heal less often will be great news for nearly everyone who isn’t the Wuju Bladesman.
- Royal Privilege (Passive): Attack Damage ratio 45% > 30%
This nerf will most definitely take away some of Qiyana’s scaling power, with a full 15% of her scaling being taken away from her auto-attack passive. The reduction of First Strike bonus damage and this change potentially leaves the Empress of the Elements in a rough spot.
- Attack Damage growth: 3.3 > 3
- Spell Shield (E): Cooldown 22/20/18/16/14s > 24/22.5/21/19.5/18s
- On the Hunt (R): Cooldown 100/85/70s > 120/100/80s
After receiving her mini-rework, Sivir felt really strong in lane. With her Spell Shield now restoring health instead of mana, she was able to stay healthy in prolonged fights, so long as the user was clever with the timing. This hefty increase in cooldown means you won’t be able to use it as often, making clever usage even more important than before.
- Snip Snip! (Q): True Damage conversion 75% > 50%
Lowering the true damage output of Gwen’s Q should make it slightly easier for opponents to itemise against her. This nerf will see Gwen finding it slightly tougher in lane against tankier champions.
- Unraveled Earth (E): Cooldown 16/15/14/13/12s > 18/17/16/15/14s
- Weaver’s Wall (R): Duration 5s > 4s
The Stoneweaver Taliyah has seen a massive resurgence since her recent rework, the damage output mixed with mobility and crowd control has seen her terrorising the jungle. Increasing the cooldown of her E ability means she may be slightly less effective in prolonged team fights. It’s important to note that her damage values haven’t been changed at all, so expect to still see the enemy champions disappear in a hail of rocks.
- Base Attack Damage: 69 > 66
A basic change, but one that Kalista mains may notice quite a bit. Her whole kit is designed around kiting your opponent with basic attacks, dashing in between each one. It’s going to take a few more hits to decimate your opponent when 12.15 gets released.
- Magic Resist: 30 > 40
- Movement Speed Duration: 1s > 1.5s
- Magic Resist: 35 > 40
- Slow Resist/Tenacity: 40% > 50%
- Health: 300 > 350
- Bonus True Damage: 10% > 9%
- Healing Conversion Percent: 65% > 55%
That’s all the information about patch 12.15 we have right now, there are a lot of changes considering Riot stated that 12.14 was the ‘last big patch before Worlds’. Expect to see mid-lane assassins and Kennen top a lot more after these buffs so prepare accordingly.
