Conjunctivius is found in the Insufferable Crypt, accessible via the Ancient Sewers. This boss has two main phases. In the first, she attacks with tentacles and projectile barrages. Focus on dodging the projectiles and destroying the tentacles quickly. In the second phase, she retreats to the ceiling, summoning more tentacles and firing a laser. Stay mobile, clear the tentacles, and attack her when she's vulnerable. Ice Bows and turrets are very effective here.
