Blizzard has released a new bluepost explaining some of the set bonus mechanics and tuning changes in Dragonflight Patch 10.1.
I’d like to share some clarifications of some details of how the set bonuses work as well as some revisions we’ve made. Your feedback has been very valuable, thank you. We’re continuing to work on and tune these bonuses, and we’ll share more updates as we make more changes.First, a couple functionality clarifications:Vengeance Demon Hunter: Fiery Brands applied by the (4) Set Bonus will gain the benefits of Revel in Pain, Charred Flesh, and Fiery Demise.Burning Alive will cause the Fiery Brand it applies to spread just like a directly cast Fiery Brand. Arcane Mage: Mana spent on Arcane Surge counts for the (4) Set Bonus. The tooltip has been updated to reflect this.
Updated BonusesSurvival Hunter (4) Set Bonus: Every 25 Focus spent reduces the cooldown of Wildfire Bomb by 1.0 sec, and the target of your latest Kill Command takes 100% increased damage from Wildfire Bomb for 8 sec. Fire Mage (4) Set Bonus: When your direct damage spells hit an enemy affected by Charring Embers 20 times the damage of your next 2 Phoenix Flames is increased by 200% and they refund a charge on use. Frost Mage: (2) Set Bonus: Flurry and Ice Lance damage increased by 10%.
Flurry causes an explosion on impact, dealing 50% of its damage to nearby enemies, damage reduced beyond 5 targets. (4) Set Bonus: Casting Ice Lance on a frozen target has a 10% chance to trigger Brain Freeze. Brewmaster Monk (4) Set Bonus: Rising Sun Kick grants a stack of Elusive Brawler, and when you dodge, the damage and critical strike chance of your next Spinning Crane Kick or Rising Sun Kick is increased by 5%, stacking up to 5.
