Important note on 3rd party apps!
Due to some of the changes made this patch, using 3rd party applications has a higher risk of crashing your game. If your game is crashing, please try updating or uninstalling any applications you use alongside League of Legends. Now back to our regularly scheduled patch note programming…
- We took Sight and Vision Wards into the shop for a model and texture update. The new wards function in exactly the same way as before, but look much prettier
- We've also revamped ranged minion attack particles. The new particles have trails that show the direction they're traveling in, giving players more information when quickly looking for minion aggro indicators
Skillshots
Context: Skillshot missiles fired
from brush or the fog of war sometimes don't register on the receiving
player's screen until they've landed, leading to sad and bewildered
champions. This fix ensures missiles are registered faster, giving
players the chance to react and realize they're being attacked.
- Skillshots fired from fog of war should appear on the enemy's screen sooner if their champion is in the path of the missile
