Monster Notes
A much larger, supernatural canine skeleton. At half health, Canis will turn red and enter a 'frenzy' mode and start rapidly hurling large bones that can temporarily trap players if they hit their mark.

Bosses no longer spawn routinely, but you can summon Canis by placing a Blood Offering on the shrine in Feasting Den (see map).
Players can spawn multiple bosses at a time, as long as they have the offerings. The player who makes the offering is the only one eligible to gain aggro once spawned.
Players can be grouped to fight Canis, but if the summoning player leaves the room or dies during combat it will regain full health. If the summoning player logs off, Canis will disappear.
