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 Artifact of Sacrifice 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 OverloadingOverloading (Affix Buff)
  Gain the power of an Overloading Elite.Attacks explode after a delay. 50% of health is replaced by shield. Elite.
• Be wary of GlacialGlacial (Affix Buff)
  Gain the power of a Glacial Elite.Leave an ice explosion on death, and apply an 80% slow on hit. Elites. Getting caught in the Jellyfish's detonation will greatly slow80% Slow (Debuff)
  Reduces movement speed by 80%. 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.

This is the logbook entry of D. Furthen, naturalist for the UES [Redacted] in conjunction with the UES Research and Documentation of Outer Life. I am joined by my good friend Tharson, who is keeping me safe through this journey.

---------------------

Today, we’ve seen our first form of outer life on this planet, merely a few hours after our untimely landing.

I will describe its properties below. I have assigned their common name as ‘Icarian Jellyfish’.

• Large, round invertebrate, about 2m in diameter, with two trailing tentacles. They shimmer a white-blue. They greatly resemble Medusozoa from Earth. 

• They seem to be experiencing neutral buoyancy in this planet’s atmosphere, causing them to float. I theorize this is due to a unique gas composition inside of their hull, which they expel to traverse.

• When observed, these Jellyfish seem to bathe in the sun, slowly rotating their bodies as they do so. They may be cold-blooded.

• By my request, Tharson approached a lone Jellyfish. After detecting his presence, it began to glow, quiver, and pulse before suddenly detonating with a brilliant flash and a loud bang, causing severe burns and temporary blindness to Tharson. I theorize that by exciting the gases inside of their hulls, these Jellyfish can ignite those gases and explode, scorching everything nearby. Tharson is OK from this encounter.
