Hello.
In our latest updates to Shadowlands,
Colossus Smash and
Warbreaker (if talented) will apply Deep Wounds from Arms Warrior’s Mastery. This change is aimed primarily at giving Arms an additional option for applying Deep Wounds in multi-target scenarios via
Warbreaker, without having to rely solely on
Bladestorm and
Cleave (if talented), and to have Deep Wounds be reliably applied to both
Colossus Smash targets when
Sweeping Strikes is active.
This change should be testable, but will not yet be reflected in the Deep Wounds tooltip.
