Patch History[]


Control Ward inventory cap reduced. Trinkets scale with average level of all champs in the game instead of owner's level. Warding Totem ward duration decreased late.

Right now, the vision game overwhelmingly favors the team that's ahead. They have the most freedom to place wards and the most gold to put into vision denial via Control Wards. While helping ahead teams close games out is one of our preseason goals, vision does so in an incredibly slow, safe manner that reduces action. With a ton of other preseason changes designed to help decided games end faster, we're pulling back on how high the winning team's vision advantage can climb.

Warding Totem

WARD DURATION : [90-180 seconds (owner lv 1-18)]
90-120 seconds (game avg lv 1-18)

Sweeping Lens removed. Oracle Alteration now available at level 1. Swapping trinkets now retains the same percentage cooldown as the previous one.

The decision-making surrounding trinket swaps is currently a bit more complicated than it needs to be. By making swaps more consistent and decreasing the number of potential swaps, we're hoping to make the gains from those swaps more clear.

This will have very little impact when it comes to sweeping wards, but it should be more fun to 'tag' fatty champions hiding in the brush
