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

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.
General
- •Updated ability icons.

- •Only the initial slash can generate a Determination stack.
Audacious Charge

Crescent Guard
- •Bug Fix: Tooltip now correctly mentions that the damage cap also applies to minions and not only monsters.
Items
Axiom Arc is both very weak and very unpopular as an AD assassin legendary. We'd like to shine it up and make it a viable part of the assassin ecosystem by letting assassins spike sooner with its purchase.
General
- •Total cost reduced to 2750 gold from 3000 gold.
- •Combine cost reduced to 363 gold from 613 gold.
Horizon Focus continues to be unpopular as an aggressive AP-Haste stat stick, especially because it's rather weak. We're here to push it up into viability by making it easier to sneak into a build and ensure the damage throughput is worthwhile.
General
- •Total cost reduced to 2750 gold from 2800 gold.
- •Combine cost reduced to 200 gold from 250 gold.
- •Ability power increased to 125 from 115.
Profane Hydra is a weak assassin item right now and it fails to fit the typical AD assassin power curve of attempting to spike early in the game. So to buff this item without ballooning late-game burst to the moon, we're making it a more competitive early option by giving it a significant price cut.
General
- •Total cost reduced to 2850 gold from 3200 gold.
- •Combine cost reduced to 313 gold from 663 gold.
- •Attack damage reduced to 55 from 60.
General
- •Bug Fix: No longer displays in the All Items grids.
