Blood - Enter the Gungeon Shrines

An ominous fountain, filled with blood. It isn't quite full...

Effect

Some enemies become highlighted in red.
Standing near highlighted enemies damages and drains them, healing the player after draining enough.
This can be used to damage enemies such as Cannonbalrog while they have disappeared.
Robot can use the shrine at the cost of 2 armor and will drain health from enemies as normal, but will not benefit from the healing effects.
The shrine's effect will carry over to a Gungeoneer's past.
