Three bell-ringers fought at once, each with its own attack. Only the one that just spoke can be hurt.

Under the chapel of Saint Orrin lie the Sexton, the Cantor and the Deacon, who tolled the plague bells for forty days and were walled in alive. Their bells still ring, and the village of Greywake hears the singing every night. Someone has to finish the tolling.
Pray
"TOLL!" (Sexton, hammer): Protect from Melee.
"KNELL!" (Deacon, violet orb): Protect from Magic.
No prayer helps with the Cantor, see below.
Move
"DIRGE!" (Cantor): a green mist fills every tile in your column. Step into another column before it lands (4 ticks).
The ringers walk a slow ring round the room. They stand still just after attacking.
Hit it
A ringer is Spent for 2 ticks right after its own attack lands (it says "...", with a white aura). Hit it then for 250% damage. At other times your hits do 20%.
Phases
Three ringers alive: a 12-tick round. Kill one and the others pause, then fight a faster 8-tick round. With one left, it fires every 6 ticks and rotates through all three attacks.
