Players will now receive a popup message when they attempt to join a game lobby that is already full.
Fixed a bug where Summoner icons were displaying incorrectly in chat rooms.
Fixed a bug where All Random Mode in Custom Games was not correctly selecting your previously used skin for a Champion.
Crystal Slash: Skarner lashes out with his claws, dealing physical damage to all nearby enemies and charging himself with Crystal Energy for several seconds if a unit is struck. If he casts Crystal Slash again while empowered by Crystal Energy, he deals bonus Magic Damage and slows all targets hit.
Crystalline Exoskeleton: Skarner gains a shield and while the shield persists his movement speed and attack speed are both increased.
Fracture: Skarner summons a blast of crystalline energy which deals damage to enemies struck and marks them. Any further damage dealt to marked targets by Skarner will allow him to consume the mark to heal himself.
Impale (Ultimate): Skarner suppresses an enemy champion and deals magic damage to it. During this time, Skarner can move freely and will drag his helpless victim around with him. When the effect ends, Skarner's target will be dealt additional damage.
Energize (Innate): Basic attacks lower the cooldowns of Skarner's abilities by 1 second against champions and 0.5 seconds against non-champions.
No longer has a 0.5 second delay before appearing. It retains the 0.5 second casting time.
Now deals half damage initially and the other half over the duration instead of it just dealing damage per second:
New: Initial 55/95/135/175/215 (+0.6 per ability power) magic damage and 11/19/27/35/43 (+0.12 per ability power) magic damage each second for the next 5 seconds.
Old: Deals 20/34/48/62/76 (+0.2 per ability power) magic damage each second for the 6 seconds the area lasts.
Fixed a bug where Siphoning Strike sometimes gained extra lifesteal.
Made adjustments to reduce the load time for games.
Made adjustments to how death and kill streaks work.
Dying to non-champions no longer resets kill streaks or increases death streaks.
Assists now reduce (not reset) death streaks.
Using Summoner Teleport on a ward will no longer reveal the ward through fog of war to enemies. Instead, it will destealth the ward to be seen if an enemy is near and reveal the teleport particle through fog of war to enemies.
Allied champions can no longer block targeting of an enemy champion if they are standing on top of one another.
Added a new in-game option for "Borderless Window Mode" that allows people to alt-tab more efficiently.
Attack-move improvements:
Attack-move targeting is now more predictable (now targets closest enemy).
Attack-move will now target visible wards.
Changed attack-move cursor color to red from green.
Added new keybindings for "Self+Smart Cast" for abilities and Summoner spells. Casting with these binds will first try to Smart-Cast the ability; if there is no target or an invalid target under the cursor, it will attempt to Self-Cast the ability.
Fixed a bug where clones did not show items in their inventories.
Fixed a bug where certain particle effects would not show up if using the minimap for targeting.
The innate ability of each champion can now be seen by browsing through the champions tab of each champion, whereas before, only the levelable abilities were shown.
After the game ends and the Victory/Defeat sign appears, all units will still move and continue to be animated.
Ping message changed from "X has marked the Y Building" to "X requests aid at the Y Building" when pinging allied buildings.
Now, you cannot ping a set amount of times within a certain timeframe.
