Stonevault is a kick-plan dungeon. A few named casts and a precise final-boss debuff clear matter more than squeezing in an extra pack.
First wing: interrupt Arcing Void, prepare a curse dispel: Cursedheart Invaders channel Arcing Void; it needs a real interrupt. Void Infection is not interruptible, so bring or plan a curse dispel instead of assuming every problem can be kicked.
Before Skarmorak: protect Piercing Wail: Void Bound Howlers' Piercing Wail is the must-stop cast. Avoid stacking too many crystal-shard deaths together on Skarmorak, because each Crystalline Eruption adds group damage.
Eirich: clear the correct player at the correct rift: Only players carrying Void Corruption should step into a Void Rift to remove it. A player without the debuff dies for entering the rift. Place Entropic Reckoning pools at the edge so later clears still have room.
These are execution priorities, not a fixed pull-count route. Verify weekly tuning, affixes, and your tank's route before the key, then use the source and current videos for difficulty-specific details.
Set the stack point before the pull and move the bosses only for a named mechanic; aimless kiting costs the melee group more damage and more time than it saves.
