  • Clown College is re-enabled, Spin To Win's R damage bonus rose from 30% to 50%, and Ultra Hydra now prevents selling Hydra items.
  • Seven Mayhem bugs were fixed across Ravenous Hydra cleave, En Passant, three Ultra Hydra exploits, Clown College critical scaling, and Rite of Ascension sealing upgraded abilities.

General Changes

Augment Offerings

Riot made another behind-the-scenes pass over champion-specific Augment pools after players reported mismatched options, such as AP-focused choices on Vayne. The stated goal is more relevant and exciting offers for each champion.

Augment Tuning

Clown College was re-enabled. Spin To Win's R ability damage increase moved from 30% to 50%. Ultra Hydra gained a sale restriction that prevents its owner from selling Hydra items.

Bugfixes

Seven fixes stop item damage from triggering upgraded Ravenous Hydra cleave; restore En Passant with multiple teammates; close three Ultra Hydra exploits involving Viego, Hydra resales, and stacked Ravenous Hydras; correct Clown College's critical scaling; and stop Rite of Ascension from sealing upgraded abilities.

Augment Changes

Clown College

  • Status: Re-enabled.

Spin To Win

  • R Ability Damage Increase: 30% => 50%.

Ultra Hydra

  • NEW Sale Restriction: Hydra items cannot be sold while this Augment is active.

Bug Fixes

  • Fixed item damage incorrectly triggering cleave while Upgrade Ravenous Hydra was active.
  • Fixed En Passant failing when two or more teammates had the Augment.
  • Fixed Viego gaining multiple Tiamats by possessing champions while Ultra Hydra was active.
  • Fixed an Ultra Hydra exploit that granted extra gold by selling and rebuying a Hydra item.
  • Fixed multiple Ravenous Hydras all receiving Upgrade Ravenous Hydra lifesteal when combined with Quest: Ultra Hydra.
  • Fixed Clown College's Deceive using an incorrect critical strike ratio.
  • Fixed Rite of Ascension sometimes sealing upgraded abilities.
