Read the guide to The Vitrarch for how to dodge each attack.
The fight
A boss floor has no clock: the waves keep coming until he falls. He steps out 1.5 s into the floor and draws his first attack 1.67 s later. While he winds up he stands still; between attacks he walks at you at 1.29 tiles a second (the Warrior walks 4.2) and his touch bites for 42. After each attack lands he rests 1.33 s before drawing the next; below half HP only 0.92 s. Knockback does not move him. No boss attack may land sooner than 0.6 s after it is drawn.

His attacks
- Shatter ring: a ring of glass shards running out from his feet to 7 tiles at 12 tiles a second, with one 52° gap in it turned at most 90° from you; wind-up 0.9 s (0.7 s below half HP); 26 base damage.
- Eclipse: 4 glass lances, each 10 tiles long and 0.8 wide, 45° apart and crossing on the spot you stand on; wind-up 1.2 s; 22 base damage; only below half HP.

What he drops
Always three rare items and three magic items, each rolled with magic and rare odds ×2.3 so any of them can come out better, and a spill of 10 coins. From floor 3 down a boss kill also has a 50% chance of a unique item (one you do not own yet, picked evenly among the ones the hero can find: 18 for the Warrior, 19 for the Mage or the Bonecaller) and from floor 4 down a 13% chance of a set piece. Every item lands on a ring around his body.
