Tactics

Step by step — what each role does: the pull, the party-wide hit turns, Taunt’s rest, phases and enrage.

When	Tank	Healer	Damage dealers
1. Pull · turn 1	Taunt before the first enemy turn: it holds the boss for 2 turns. Keep a defensive card for “Umbral Bolt”.	Heal the tank from turn one: they lose 23% of their Health per turn on average, but never more than 2,383 per turn.	Steady damage on the boss — no burst while the tank builds threat.
2. Turns 3, 6, 9… · ⚡ “Flame Torrent”	A hit on everyone — up to 698 to you: the stance holds, don’t waste anything.	On the turn before (a warning on the boss portrait) — everyone above half Health and shields; each takes up to 698. After it — heal the party.	Your own shield or self-heal before the hit, if you have one; keep dealing damage: above half Health the hit is not a threat.
3. Turns 3, 6, 9… · Taunt rests	The stance holds (−40% damage): hit the boss — your damage makes 3× threat. Next turn — Taunt again.	As usual: heal the tank.	No burst — don’t out-threat the tank, or the boss turns on you.
4. Boss shield and heals: “Barrier of Light”, “Layered Aura”, “Gift of Light” and “Renew”	Keep Taunt on rhythm — nothing changes.	As usual.	The boss’s shield soaks damage first — play big cards when it is down; steady damage every turn.
5. Phase change: 20% of the boss’s Health	Reach the threshold at full Health with Taunt ready.	Top the party to full Health before the threshold — a new phase brings new moves.	Party hurt — hold damage at the threshold until the healer catches up.
6. Below 20% of the boss’s Health · enrage	Defensive cards now: the boss’s damage grows 18% every turn.	Don’t save heals, shields on the tank.	All big cards now: finish it fast.

How much reaches a hero

To the tank (Health ~2,650): up to 2,118 per hit and up to 2,383 per whole boss turn.
To everyone else (Health ~1,300–1,500): up to 885 per hit and up to 1,125 per turn.
A card can read more than a hero’s whole Health — that is not a mistake: the card is strong, but a hero never takes more than the cap per hit. A shield takes the hit first and is used up in full; past the shield, no more than the cap reaches Health.
The numbers are for a level 60 hero in PvE gear; your Health differs — the cap follows it: per hit 80% of the tank’s Health and 59% of anyone else’s, per turn — 90% and 75%.

Abilities

“To a hero” is the most that reaches a level 60 hero’s Health (hit cap applied, before Hardiness). “On the card” is what the boss card reads: it can be more than a hero’s whole Health, and that is not a mistake — the card is strong, but no more than the cap lands per hit. Bold — the most dangerous. More — How to read the guide.

Ability	What it does	On whom	To a hero	On the card	First turn	Cooldown	Lasts	Removed	When
Flame Torrent	Hits the whole party	whole party	up to 698 each	698	3rd	every 3 turns	—	—	whole fight

Why the card reads more

Umbral Bolt. A strong card — it reads 3,364, but the tank never takes more than 2,118 per hit (the cap is 80% of their Health); a shield is used up in full first. On any other hero — up to 885.

Turn-by-turn rhythm

A boss turn is the enemy turn after yours; the party moves first. The boss’s Onslaught hits the target every other turn, its cards whenever it has crystals (each has its own cooldown — see the table above). Here is what follows a strict turn order.

Boss turn	What happens
1	Tank presses Taunt before this turn — it holds turns 1–2
2	Regular turn: hits on the tank
3	Taunt is resting: the stance (−40% damage) keeps the boss on the tank — damage dealers, no burst · ⚠ On your turn before it, a warning shows on the boss portrait: healer tops everyone above half Health, shields up. ⚡ “Flame Torrent” hits the whole party: up to 698 each
4	Tank presses Taunt before this turn — it holds turns 4–5
5	Without healing the tank falls on this turn
6	Taunt is resting: the stance (−40% damage) keeps the boss on the tank — damage dealers, no burst · ⚠ On your turn before it, a warning shows on the boss portrait: healer tops everyone above half Health, shields up. ⚡ “Flame Torrent” hits the whole party: up to 698 each
7	Tank presses Taunt before this turn — it holds turns 7–8
8	Regular turn: hits on the tank
9	Taunt is resting: the stance (−40% damage) keeps the boss on the tank — damage dealers, no burst · ⚠ On your turn before it, a warning shows on the boss portrait: healer tops everyone above half Health, shields up. ⚡ “Flame Torrent” hits the whole party: up to 698 each

Phases and enrage

From 20% Health — phase 2: the deck is reshuffled, same moves.
Below 20% Health — enrage: +18% to its damage every boss turn until the end of the fight.

Roles

Tank: tanking and when to taunt

Taunt before boss turns 1, 4, 7…: it holds the boss for 2 turns, then the button rests for 1 turn — the stance (−40% damage) still holds then.
You lose 23% of your Health per boss turn on average, up to 51% on a heavy turn.
Keep defensive cards for “Umbral Bolt” — it is the hardest hit on you.
Save defensive cards for the enrage — below 20% of the boss’s Health.
Without healing you would fall on boss turn 5.

Healer: when to heal

Main healing goes on the tank every turn: they lose 23% of their Health per boss turn on average.
“Flame Torrent” lands on boss turns 3, 6, 9…: up to 698 each. On your turn before it, a warning shows on the boss portrait — top everyone above half Health and shield; heal the party after the hit.
The others survive all 10 turns of the test without healing — all healing can go to the tank and after party-wide hits.

Damage dealers: what to hit and when

Boss Health — 54,254.
The boss shields itself (“Barrier of Light” and “Layered Aura”) — the shield soaks damage first; play your big cards when it is down.
The boss heals itself (“Gift of Light” and “Renew”) — steady damage every turn beats rare big hits.
Before 20% of the boss’s Health, hold damage if the party is hurt: a new phase brings new moves.
Below 20% — enrage: save your big cards for this stretch and finish fast.
Don’t outpace the tank’s threat on Taunt’s rest turn (boss turns 3, 6, 9…): the tank’s damage makes 3× threat, but a burst can still pull the boss.

Danger points

Boss turns 3, 6, 9…: “Flame Torrent” hits the whole party — up to 698 each; Hardiness lowers it further. The warning comes on your turn before the hit.
The hardest hit on the target is “Umbral Bolt”. The card reads 3,364, but the tank takes at most 2,118 per hit, anyone else 885; a whole boss turn — at most 2,383 to the tank and 1,125 to the others. Nobody at full Health falls in a single turn.
Below 20% of the boss’s Health — enrage: its damage grows every turn. Drag the fight out and you lose.
Phase change at 20% Health — a new deck; enter it with the party at full Health.

Average damage

Measured by the game engine: a level 60 party in PvE gear, the tank holds Taunt, nobody else does anything — 10 turns of the boss. Percentages are the share of Health one boss turn takes: that is what needs healing.

Mode	Tank: per turn	Tank: heavy turn	Others: per turn	Others: heavy turn	Without healing would fall on boss turn
Normal	23%	51%	9%	32%	tank — turn 5, healer — alive, fighter — alive

Party and gear

Party: 3 heroes — tank, healer, damage dealer.
Dungeons have no item level advice: gear of your own level is enough (the place is levels 55–60, the boss is level 60).
The guide’s numbers are for a party of “one player + level 60 residents”; with another line-up the boss’s strength differs a little — the game fits it to the party.

Loot

All of the boss’s loot with rough drop chances is in the item atlas; rules and items by boss are on the Upper Cindermount Spire page.

Previous boss — Warlord Drakkisar, Cult Commander.

All bosses of the place — Upper Cindermount Spire. Party combat rules — How to beat: level 60 bosses.
