Fixed several bugs that could cause Yunara to deal more or less damage with on-hit effects.
Cultivation of Spirit
- •Bug Fix: On-hit damage on spread attacks caused by Runaan's Hurricane Wind's Fury bolts that hit the primary target now properly apply at reduced effectiveness instead of full effectiveness (as if a primary attack hit them).
- •Bug Fix: Runaan's Hurricane Wind's Fury bolt damage is no longer incorrectly also modified by Cultivation of Spirit's reduced on-hit effectiveness on each of the bolts' primary targets.
- •Bug Fix: Item on-hit effects no longer fail to deal damage on valid targets when a sufficiently large number of spread attacks are taking place simultaneously.
- •Bug Fix: Item on-hit effects which stack now gain and consume stacks at the correct timing and can no longer sometimes trigger twice per individual hit when a sufficiently large number of spread attacks are taking place simultaneously.
Between Worlds
- •Bug Fix: Tooltip now notes the correct rift duration.
Royal Maelstrom
- •Bug Fix: Navori Flickerblade Transcendence now properly applies to Void Surge per-direction cooldown when triggering it via Royal Maelstrom. Previously, the visual indicator for direction availability still lit up as if the effect was applied and the direction was available, even though it could not actually be cast, due to the bug.
Static Field
- •Undocumented: Bolt damage now applies as default damage instead of spell damage.
Blood Frenzy
- •Bug Fix: No longer sometimes has a brief delay before aggroing a valid target.
Powder Keg
- •Bug Fix: Explosion no longer sometimes cancels his and enemies' attack.
General
- •Bug Fix: Other players no longer see a debug icon on his status bar in his target frame.
Arcane Inventor
- •Transform Mercury Cannon
- •Bug Fix: Restored empowered attack primed SFX.
Tunnel
- •Bug Fix: No longer unintentionally causes her to enter combat upon casting the ability.
Ferromancy: Crash Down
- •Bug Fix: Tooltip now notes the proper shield health ratio in accordance with the V25.16 change.
Sovereign's Domination
- •Bug Fix: Enemies' Sundered Sky Lightshield Strike no longer sometimes fails to incur its cooldown on Viego who has entered possession at least once during the game, allowing them to illegally trigger the effect on him twice.
Siphon Power
- •Bug Fix: Tooltip now notes the correct buff duration for Discharge's attack of 4 seconds instead of 3.5.
