Reborn Irukandji can be found in The Deep surrounding the Leviathan. They will maintain the spirit of Disenchantment up as much as they can. Whenever one of them is killed, it will be resurrected shortly after.
Taking these Irukandji out may not be as useful as simply taking out their spirits which are more fragile and take some time to recharge.
Remember to leave the last Reborn Irukandji alive in the room of the Leviathan. This Irukandji will make pulling groups in the next room and surviving the Kanaxai Aspect of Scorpions easier.
