QUICK ANSWER
Remember These First
Zalmarath is huge, so hitbox reads can feel off — that is normal giant-boss behaviour, not always a bug.
After the kill, the Flame Ruby is the quest item for A Crown of Stone.
The giant model can make projectiles look like they pass through; confirm with hit feedback, not just visuals.
He plants a sword; stand behind it during the arena-wide beam.
The arena shrinks but does not instantly fail you — keep a safe edge, do not roll off.

BEFORE THE FIGHT
Pre-Fight Preparation Checklist
| Done | Check | Why it matters | Quick fix |
|---|---|---|---|
| Physical defence Most hits are giant physical swings. | Big telegraphed hits still delete low life. | Life/armour and side positioning. | |
| Fire resistance The laser and some slams are Fire. | The arena-wide beam is fire pressure. | Raise Fire res for the cover window. | |
| Movement speed You must reach the sword in time. | Slow characters get caught by the beam. | Boots with movement speed. |
ARENA READING
Arena Reading
The grotto is a platform arena. Zalmarath plants his sword mid-fight; that sword is your cover during the arena-wide Baleful Gaze beam.
The platform changes over the fight — edges may break, but you are not instantly failed. Keep a safe inner edge and never roll off.
- Blue = safe inner edge. Orange = sword cover. Red = laser sweep. Green = add-clear lane.

Phase Breakdown

DAMAGE PROFILE
Damage Profile
Physical
- Life/armour and swing timing.
Sweeps, bolts and adds are physical.
Fire
- Fire res and sword cover.
The arena-wide beam is fire.
STRATEGY
Strategy and Key Mechanics
Sword Cover Mechanic — Zalmarath plants his sword; an arena-wide attack winds up; move behind the sword; the sword blocks the beam; after it ends, re-engage.
Reported Issues — separate three things: (1) normal giant hitbox reads, (2) visual misjudgement from the model size, (3) currently reproducible bugs. Do not treat a visual oddity as a standard strategy, and do not assume every old hitbox bug still exists.
Platform State — initial platform is complete; mid-fight the boss shifts and bolts increase; adds enter and box you; later edges break and safe space shrinks. Keep a safe inner edge; never roll off.
- Melee: punish after the sweep, not during the beam.
- Ranged: keep the sword in view so cover is always reachable.
- If projectiles look like they pass through, confirm by hit feedback, not visuals.

COMMUNITY EVIDENCE
What Players Commonly Struggle With
How do I survive the arena-wide beam?
Players get hit by the full laser.
The planted sword is the intended cover.
Move behind the sword he plants during the wind-up.
My hits pass through him / targeting feels wrong.
Players report model-size confusion.
Some is normal giant hitbox; some is visual misjudgement. Confirm by feedback.
Trust hit feedback over visuals; report reproducible bugs separately.
Does the platform shrink until I fail?
Players fear an instant-fail timer.
Edges break but it is not an instant fail.
Keep a safe inner edge; never roll off the broken edge.
PROBLEMS & DIRECT ANSWERS
Problems and Direct Answers
The laser deletes me every time.
Direct answer: You are not using the sword cover. Move behind the planted sword during the wind-up.
- Watch for the sword plant.
- Reach it before the beam fires.
- Raise Fire res for the window.
My skills look like they miss.
Direct answer: Confirm by hit feedback, not visuals — the giant model causes misreads. Reproducible bugs are separate from normal hitbox.
- Check damage numbers.
- Do not assume every oddity is a bug.
- Report consistent misses with proof.
I rolled off the platform.
Direct answer: Edges break but it is not instant fail. Keep a safe inner edge and never roll toward the broken edge.
- Stay inner.
- Clear adds blocking your path.
- Do not panic-roll at edges.
