The fight (tap to show)
- Mechanic damage
This boss's marks deal a fixed amount set for its level (83), in place of the blow multiples below: a move you could dodge 1,620 damage, a hazard 1,418 damage, its signature failed 2,228 damage, burning ground 486 damage a second. More levels and better gear mean more health, so the same hit takes a smaller part of it. Armour, shields and barriers turn aside at most 20% of it.
- The yard and the stair
In the yard the Stormcallers call spark clouds at their feet; a plate by the little vane turns the yard's wind: a cloud that bursts on them leaves them reeling. On the inner stair the Warder drops a knotted rope: its first knot throws the next wisps away, its second over the landing's edge.
- Windrose
Four wind doors in the stone floor's walls, a brass plate before each with its arrow to its door: one standing 1 s on a plate opens that door and shuts the others. Every 22 s (first at 10 s) Corvin lets loose Flour and Spark over the millstone: a cloud 4 tiles round that bursts after 8 s: 2 Charged stacks on whoever is in it, and if it misses him 2,228 damage. The open door's wind carries it 1.5 tiles a second; the doors shut as it bursts. The burst catching Corvin: FLOUR BURST! He reels 4 s, takes 30% more for 8 s, and his Gathering Charge breaks. From 50%, 3 s before each burst he slams the open door and opens the one across (Contrary Wind); from 25% two clouds, one each side of the stone, one wind for both.
TipThe tank holds him downwind, where the cloud will go; someone opens the door the cloud should blow from, everyone else steps out of it. Watch for the slammed door. Alone the cloud bursts after 6 s and drifts 2 tiles a second, and he never slams a door.
- Bottle Rain
1/2/3 circles 2 tiles round under the party: the flash, then the thunder 1.8 s later, 1.5 blows of lightning and 1 Charged stacks.
WhenOne of them every 7 s, first at 6 s.
- Gathering Charge
He stands and gathers for 3 s: a skill breaks it (he reels 2 s); unbroken, everyone takes 1 Charged stacks.
WhenOne of them every 7 s, first at 6 s.
- Spark Line
A strip 1.5 tiles wide from him through the one farthest away, 13 tiles long: 1.8 blows of lightning 1.5 s after it is marked.
WhenOne of them every 7 s, first at 6 s.
- Rage
It flushes red and rages: its normal blows come 1.3× as often, and all its blows are 15% harder.
WhenAt 30% of its health; it lasts to the end of the fight.
TipThe last part is the most dangerous: save your strong skills and potions for it, and dodging the marks matters more than ever.
