When a Capsarius detects a fellow member that is under attack by the player, it will focus its attention on them, providing a healing effect that restores 100 of their health every 2 ticks. Throughout the whole healing process, the targeted member will also gain a massive damage reduction buff that will disappear when all of its health is recovered or the Capsarius healing them dies.
They are somewhat uncommon in the dungeon, as most areas often contain one Capsarius. Some areas may contain two or no Capsarii.
This monster's name comes from the Latin word 'capsarius', meaning a slave who took care of things. Usually this was referred to those who served as help for doctors practising medicine, which bears similarities to this monster's ability to heal other monsters.
They appear to be female, yet have a masculine Latin name (rather than being called "Capsaria").
This monster and the other monsters in the dungeon are the first to have a weakness to a generic attack style (in this case, Ranged). These weaknesses were previously restricted to players.
A hidden update increased the healing radius of the Capsarius.
Sometimes, a rare glitch may occur where a Capsarius has died before it is able to heal. When this glitch happens, the monster it was supposed to be healing will gain the defensive buffs without healing, making it hard to kill monsters affected by this. This happens in places with Capsarius and in Legio Tertius' room.
When healing, there are a few exceptions:
If a Capsarius dies while healing a target, that target will still retain the shields for three ticks.
If a Capsarius is stunned while healing a target, that target will retain the shield for a tick, then lose the shield until the stun effect wears off.
If there are multiple wounded targets, the Capsarius randomly heal one of the targets. Upon attacking one of them, the Capsarius will immediately heal your current target.
