The Glass Serpent

This boss's marks deal a fixed amount set for its level (70), in place of the blow multiples below: a move you could dodge 1,156 damage, a hazard 1,012 damage, its signature failed 1,590 damage, burning ground 347 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.

It marks a circle under each of its nearest foes (1/2/3 for 1, 2–3 and 4–5 players; radius 2 tiles); 1.8 s later all of them strike at once, 1.5 × a normal blow to whoever is inside. It calls out: "Glass shards fall!"

EnragedEvery 9 s.

TipStep out of your own circle, not into a neighbour's: keep a little apart.

She gathers the cave's light for 2.5 s; her eye shows red or gold. Red: whoever faces her is dazzled 3 s (you see 3 tiles round you), gains 2 Frost and takes 1,590 damage. Gold: whoever faces her catches a prism (+12% on her for 10 s); 1/2/3 of you overload her glass: she reels 3 s and takes 25% more for 6 s.

When8 s into the fight, then every 16 s.

TipYour facing is what counts: turn your back at the red, turn to her at the gold. Striking turns you to your target, so ranged fighters hold their blows at the red.

The gold and the red come one after the other, 1.5 s apart: look, then turn away.

WhenAt 60% health.

TipFace her for the gold, and turn at once.
