Turrets & Structures Changes

Patch 26.3

change

Turrets

  • Turret Plates
  • Bonus resistances changed to 30/30/50 (based on number of nearby enemy champions) from 20 to 100.
  • Reactive VFX when hit by champions are now smaller, especially if the turret was recently attacked.

Patch 26.1

change

Turrets

  • Updated icons.
  • Removed: No longer has lane swapped detector.
  • New Effect: First Turret now grants a bonus 300 gold.
  • New Effect: Turrets now take 20% increased damage from melee champions.
  • Crystalline Overgrowth
  • New Effect: Targetable lane turrets are now subject to Crystalline Overgrowth.
  • Crystalline Overgrowth will appear after a 90 seconds startup/cooldown (30 seconds in Swiftplay); at that point, the turret will take true damage the next time an enemy champion attacks it.
  • The overgrowth will stay at its minimum damage state for 60 seconds (30 seconds in Swiftplay), then scale the damage up linearly for 240 seconds (180 seconds in Swiftplay), then hold at max damage indefinitely.
  • The damage calculation is based on the average level of the attacking team:
  • At level 1, the damage range is 2% - 3.3% of the turret's max Health (2.15% - 3.76% in Swiftplay).
  • At level 18, the damage range is 8.8% - 18.9% of the turret's max Health (13.2% - 39.6% in Swiftplay).
  • The attack hitbox of the turret is increased for melee champions based on the size of the overgrowth.
  • Crystalline overgrowth will not trigger from attacks while the turret has backdoor protection.
  • If an enemy unit is near the turret at that 90 second mark when it would become active, Crystalline Overgrowth will be suppressed and not appear. Once enemies are gone, the Overgrowth will then be applied and it will "fast forward" its state to make up for where it should be. This is to avoid sudden mid-push activations.
  • Warden's Eye
  • True sight range increased to 1100 units from 1095.
  • Turret Plating
