The Brimstone Heart

This boss's marks deal a fixed amount set for its level (45), in place of the blow multiples below: a move you could dodge 554 damage, a hazard 484 damage, its signature failed 761 damage, burning ground 166 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.

Its crust of sulphur takes up to 60% off every blow (the bar under its own). Stand in one of the guild's lime pits 0.8 s and you are limed for 14 s: only a limed blow cracks the crust (3% of its health in limed blows cracks it whole). It grows back 3% a second. Cracked to nothing it breaks: stunned 2 s, it takes 50% more for 10 s. Alone: lime 18 s, cracked at 2.5%.

WhenThe whole fight.

EnragedFrom 30%: it grows back 4.5% a second.

TipLime up, strike, go back for more; when it breaks, everything at it.

The crust swells, warned 4 s ahead (alone 5 s): if more than 50% of it stands when it bursts, everyone in the fight takes 761 damage; cracked further, it bursts harmless.

When20 s into the fight, then every 30 s.

EnragedEvery 26 s.

TipHave the crust under half before every nova: limed blows, early.

A 100° cone 5.5 tiles long at the one holding it, 1.5 s ahead: 2 × a normal blow on them, 554 damage on anyone else in it. It burns the lime off whoever it touches.

When7 s into the fight, then every 10 s.

EnragedEvery 8 s.

TipThe tank turns it away from the limed.

Four lanes of blue fire from the Heart, 1.4 tiles wide and 12 tiles long, a cross then a saltire in turn, 1.6 s ahead (alone 2 s): 554 damage. Every 9 s.

WhenFrom 30% of its health.

TipStand between the lanes; the next set turns by an eighth.

It shouts: "Molten sulphur crawls out of the vents!" 1/2/2 Brimstone Ooze (level 44) come and attack the boss's target.

WhenAt 65% and 40% of its health, once each.

TipKill them first.

Circles under 1/2/3 of the party (1.5 tiles; 1, 2–3, 4–5 players), 1.6 s ahead: 554 damage and Sulphur Poison for 6 s. Where one lands a sulphur lake burns for 5 s, slowing by 70%.

When9 s into the fight, then every 12 s.

EnragedEvery 10 s.

TipStep out of the circle, and leave the lakes away from the lime pits.

Two of its 6 side vents facing each other erupt, warned 1.8 s ahead (1.8 tiles round): 484 damage. Every 7 s, round the six in turn.

WhenFrom 65% of its health.

TipStep off the vent that glows; melee shifts round the Heart.

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.
