Jellyfish

The  is a returning airborne monster in Risk of Rain 2.

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.

Self-Detonation
When the Jellyfish comes close enough to its target, it glows and prepares to explode. After a moment, it bursts into a large ball of electricity, 1000% damage with a proc coefficient of 2.0. The explosion suffers from sweet spot falloff.

Attacking the Jellyfish and dealing sufficient damage will interrupt its charging sequence.

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

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 much more vulnerable to being completely frozen by the following ice blast. Taking any damage from such an Elite makes fleeing from other nearby Jellyfishes extremely difficult, and the player might be swarmed by many exploding Jellyfishes.
 * Interrupting the detonation requires dealing a certain percentage of the Jellyfish's health over a short period of time, meaning that an Elite Jellyfish's Self-Detonation can be difficult to interrupt.
