Patch 25.8

change

Unsealed Spellbook

  • Bug Fix: Attacking ward-type units no longer counts as entering combat for the purposes of accessing the spell swapping interface.

Patch 25.S1.3

change

Unsealed Spellbook

  • Bug Fix: After swapping one slot to Unleashed Teleport, using Unleashed Teleport to teleport to a distance that requires more than five seconds of channeling, which illegally activates its slot's swap menu during the remaining travel, then selecting another summoner spell—the swap for which subsequently fails, allowing the user to keep Unleashed Teleport in the first slot—and also swapping the second slot to three different summoner spells (as per Unsealed Spellbook's cooldown): no longer illegally allows the second slot to be swapped to a duplicate Unleashed Teleport, which after each slot's use swap back to the player's initial first summoner spell slot, resulting in a duplicate of the original slot as well. If the player has equipped Flash and Hextech Flashtraption, their non-Flash slot would become Hexflash instead of their original Flash slot, thus allowing both slot selections of Flash to be permanent (cooldowns normally incurred).

Patch 25.S1.2

change
