The Rat King gets a new kit, the Druid's forms hit harder, and bots make better use of their champions.
The full notes list every change, with the numbers.
A new map, the older siege: the whole battlefield is repainted as the ruins of the war that broke the Moonforge. Every champion now speaks, and three highlights follow every match.
Rimecoil, the Glacier Wyrm, arrives as a raid boss once a game. At 15:00 it breaks the map open into a frozen bowl. Slay it and your champions deal 25% more damage to enemy minions for the rest of the game.
Three Eclipse items bring your ultimate back sooner. The Hookman's hook reaches twice as far, and the Crescent moves in close for top or jungle.
