Jellyfish

The  is a returning airborne monster in Risk of Rain 2, and is part of the monster family.

Skill & Behavior
Jellyfishes spawn on the outskirts of an Environment and typically float in place. Once they spot a target, they fly slowly towards it in a typical swimming motion.

Any single instance of damage that deals more than 20% of the Jellyfish's total health will stun it and interrupt its attacks or movement.

Self-Detonation
When the Jellyfish comes close enough to its target, it glows and prepares to explode. After 1 seconds (scales with attack speed), it bursts into a large ball of electricity, dealing 1200% damage with a proc coefficient of 2.0 in a radius of 10m with sweet spot falloff. During the detonation sequence the Jellyfish will continue following the trajectory it had before activating the skill.

Self-exploded Jellyfish do not drop any gold, although they may still drop items when the is enabled.

This skill has a cooldown of 5 seconds. Normally this is irrelevant, but it can come into play if the skill is interrupted.

Behaviors

 * 1) Use secondary: the Jellyfish must be within 8m from its target. The Jellyfish will ignore the node graph for homing in directly on the target.
 * 2) Chase while waiting for secondary: the Jellyfish must be within 8m from its target. Similar to the previous behavior it will home in directly on the target, trying to keep the distance as close as possible to detonate at the first opportunity.
 * 3) Chase from afar off nodegraph: the Jellyfish must be within 100m from its target and have line of sight. This behavior also ignores the nodegraph for the most direct pathing. This is not as issue even over cliffs since the Jellyfish is a flyer.
 * 4) Chase: no requirements. The Jellyfish will use the node graph to approach its target.

Tips

 * While the Jellyfish's explosion does suffer from damage falloff, it can be lethal when it hits for full damage. It can effectively one-shot a Survivor if the Jellyfish is an Elite.
 * Be wary of Elites. Getting caught in the Jellyfish's detonation will  the player, making them more vulnerable to being completely frozen by the following ice blast. Taking any damage from such an Elite makes fleeing from other nearby Jellyfishes more difficult, making the player an easy target for other enemies.
 * Interrupting the detonation of a Jellyfish requires dealing a certain percentage of the health to the enemy in a short period of time, meaning that an Elite Jellyfish's Self-Detonation can be difficult to interrupt.
