Other items

Demonic Embrace
Demonic has been a strong contributor for enhanced clear speed times, especially on the likes of a few top tier picks like Maokai, Udyr, and Amumu. We’re now capping Demonic’s damage against monsters so it isn’t quite as effective

Doran's Shield
Doran's Shield is a very strong early game purchase for both tanks and fighters that makes a lot of champions feel less punishable than desired. This nerf aims to lower the passive healing without discouraging interaction based healing.
Runes you recently played

Other runes

Magical Footwear
Pro players are sometimes going Magical Footwear and selling the boots when they get them to use the gold to accelerate their mythic item purchases. This circumvents the original intent of the item (to grant you boots) so we want to bring down the power level of this particular strategy.

Treasure Hunter
Treasure Hunter is far and away one of the best runes to pick up in your secondary rune tree for almost all champions. It is currently contributing to a lot of early snowballing, so we’re taking away some of the gold that helped it become a top-tier rune.
