Holy Water item
Holy Water is a familiar in The Binding of Isaac.
Description
Spawns a familiar that follows Isaac around and launches itself while Isaac is shooting.
Upon hitting an enemy, the familiar deals 7 damage and shatters, creating a pool of damaging blue creep that petrifies enemies that come in contact with it.
The pool lasts for ~9 seconds and deals 8 damage per tick (24 per second).
Once the pool disappears completely, Holy Water will respawn and can be launched again.
It will not respawn immediately after entering a new room.
