Bloodied

Monsters are dangerous creatures, if they weren't, then adventurers would be out of a job. Like any creature, though, a monster that is hurt and wounded becomes more dangerous, lashing out and unleashing their most powerful abilities at their attackers.

When a creature becomes bloodied, it is often a moment of realization. That the situation they are in is very dangerous and that the individuals they are facing off with must be dealt with quickly.

A monster becomes bloodied when they are reduced to half their maximum hit points or lower.

When a creature becomes bloodied, a variety of different things can happen based on the creature. Each creature will react differently to being bloodied, based on how they fight.

Once a creature becomes bloodied, they remain bloodied even after gaining healing that heal them above their bloodied threshold. They only stop becoming bloodied, or can reactivate a feature that happens when they become bloodied, once combat stops and they finish a long rest.
