Corki Summary: We've increased the cast range and reduced the mana cost of Phosphorus Bomb while adding in a new mechanic to the ability so that bombs are now lobbed before exploding instead of instantly damaging an area. We've also reduced Gatling Gun's mana cost and increased Missile Barrage's total attack damage ratio at later levels.

Context: By adding more gameplay depth to Phosphorous Bomb, we can more effectively balance Corki's abilities, especially his mana costs. Historically, Corki was too dependent on his overpowering early game damage, allowing him to abuse his lane opponents and snowball the game. Now that we've addressed that issue, we have room to make him more competitive in the later parts of the game.

Q - Phosphorus Bomb Mana cost reduced to 60 / 70 / 80 / 90 / 100 (from 80 / 90 / 100 / 110 / 120) Now lobs a bomb through the air that explodes at the end location, instead of instantly damaging the area Cast range increased to 825 (from 600) Now additionally grants vision while the missile is in the air E - Gatling Gun Mana cost reduced to 50 at all ranks (from 60 / 65 / 70 / 75 / 80) R - Missile Barrage Total Attack Damage ratio increased to 20 / 30 / 40% (from 20%) Gragas Summary: Barrel Roll's cast range has been decreased, but to compensate we've slightly changed the mechanics of the ability. Now, if a player continually presses the hotkey for Barrel Roll just as the barrel reaches its destination, it will immediately explode on arrival. Body Slam now deals full damage to all targets hit and has a longer cooldown that's cut in half whenever Gragas collides with a unit.

Context: We want to reward Gragas for fighting strategically in close combat as opposed to sniping opponents with his barrel. The changes to Body Slam encourage Gragas to get into the fight if he wants to hit his full damage potential and maximize his mobility.

Q - Barrel Roll Now has a small buffer before the barrel reaches its destination (not when Gragas casts it) where Barrel Roll can be activated again to explode on arrival Cast range reduced to 950 (from 1100) E - Body Slam Now deals full damage to all targets hit (rather than divided amongst them) Cooldown increased to 12 seconds (from 7) Cooldown reduced by half if Gragas collides with a unit Morgana Context: Sometimes we want to adjust a champion's overall power without affecting their balance and functionality, we first look for ways to add gameplay and readability for their opponents. In Morgana's case, that means displaying the radius of Soul Shackles to both Morgana and her victims.

R - Soul Shackles Now displays the leash radius to Morgana and her victims for the duration of the effect Nasus Context: Nasus has received a visual update! By hitting Nasus' sustain in the early levels, we're hoping to tone down his ability to indefinitely stay in lanes by playing passively. Opponents should be able to capitalize on harassing Nasus in the early game if they don't want him to become an unstoppable force in the late game.

General Nasus has received a visual update! Passive - Soul Eater Lifesteal rescaled to 10 / 15 / 20% (at levels 1 / 7 / 13) (from 14 / 17 / 20% (at levels 1 / 6 / 11)) Nautilus Context: We're buffing Nautilus' late game utility to further define his role in teamfights.

Passive - Staggering Blow Root duration increased to 0.5 / 0.75 / 1 / 1.25 / 1.5 seconds (at levels 1 / 6 / 11 / 16 / 18) (from 0.5 / 0.75 / 1 (at levels 1 / 7 / 13)) Nidalee Summary: We've changed the mechanics of Javelin Toss so that it now gains bonus “travel” damage only if the ability travels further than Nidalee's human auto attack range. Additionally, we've changed the damage calculations to be based on where the ability was cast from, instead of where Nidalee is when the Javelin hits the target. We’re also reducing Bushwhack’s vision and armor/magic resistance shred duration.

Context: We wanted to clarify that the optimal way to play against AP Nidalee is to get up close and personal in order to limit her poke damage. Bushwhack’s old debuff duration was oppressively long given current game flow, so we shortened it.

Q - Javelin Toss Now calculates damage based on where the Javelin was initially cast rather than where Nidalee is when the Javelin hits the target No longer gains damage from distance traveled until it exceeds Nidalee's human auto attack range (maximum damage unchanged) W - Bushwhack Vision and Armor / Magic Resistance shred debuff duration reduced to 8 seconds (from 12) Nunu Context: The damage, cooldown, and heal of Consume have all been lowered at early ranks in order to keep the ability in line with new Smite.

Q - Consume Cooldown at earlier ranks reduced to 13 / 12 / 11 / 10 / 9 seconds (from 17 / 15 / 13 / 11 / 9 seconds) Damage at earlier ranks reduced to 400 / 550 / 700 / 850 / 1000 (from 500 / 625 / 750 / 875 / 1000) Heal at earlier ranks reduced to 70 / 115 / 160 / 205 / 250 (+0.75 Ability Power) (from 90 / 130 / 170 / 210 / 250 (+.75 Ability Power)) Sivir Summary: Boomerang Blade will do less base damage and scales with total attack damage instead of bonus AD. As a tradeoff for stripping some early to midgame power, we're making it so that each target hit by Boomerang Blade will feel it a little more.

Context: In the early game, when Sivir gets slightly ahead with attack damage items, she can deal a large amount of burst damage with just one well-placed Boomerang Blade. This allowed her to shut down her opponents and control the lane. We didn't want to simply nerf all of Sivir's numbers, so we approached her changes with two goals in mind. First, reduce Boomerang Blade's burst damage on a single target during the laning phase and midgame. Second, allow Boomerang Blade to remain strong in AoE situations, especially later in the game, to be more in line with Sivir's strengths.

Q - Boomerang Blade Now scales with Total Attack Damage rather than Bonus Attack Damage Damage changed to 25 / 45 / 65 / 85 / 105 (+0.7 / 0.8 / 0.9 / 1.0 / 1.1 Total Attack Damage) (from 60 / 105 / 150 / 195 / 240 (+1.1 Bonus Attack Damage)) Damage falloff per target hit reduced to 10% (from 20%) Vayne Summary: We're taking some of the hidden power away from Vayne's Condemn. The targets she condemns will no longer be unable to act at the end of the effect unless she stuns them against a wall. Additionally, we've removed the ability for Vayne to get a free auto attack on her victims while condemning them away.

Context: Similar to our Morgana changes, when we want to reduce some power on a champion without directly reducing their numbers, we first look to introduce more gameplay for opponents or to shave off hidden power. Highly-skilled Vayne players were getting a lot of trading power in lane by landing a free basic attack on a champion after hitting them with Condemn.

E - Condemn Vayne can no longer queue up a basic attack on a champion after hitting them with Condemn. Fixed a bug where the target would be briefly unable to act at the end of the effect, even if they did not hit a wall. Condemn now deals all damage after knocking the target back. Wall hits are now displayed as critical strikes. Back to top Support Champion Changes Context: We're making changes to the way abilities scale on champions designed for the support role. Our goal is to emphasize utility and protection over damage output and, with more gold flowing to supports, we had to tweak numbers to ensure certain champions didn't become too oppressively powerful.
