- Rumor has it this daemon wanders the wasteland, slaying any man or monster that crosses its path and ingesting their corpses in order to fuel its own growth. Superior to the more common deathclaw, only expert hunters stand a chance against this wicked creature of the night.

Iseultalon is strong and can quickly decimate the party. It uses both physical and magical attacks. It employs Dark-elemental attacks and is weak to shields, machinery and Fire. It projects a strong beam that knocks back everything it hits. It swipes with its tail and can quickly turn around to hit those who try blindside-strikes. It pounces on targets further away and swipes at those near it with its large claws. Its claws detach, and Iseultalon can send them flying about itself, hurl them at faraway targets, and use them to draw lines of laser onto the ground it front of itself. When it becomes Vulnerable, it grouches down and temporarily stops attacking.
When fought as a hunt, Aranea has a chance to randomly join in.
On rare occasions, it may interrupt its own attack animations with more attacks.
It can be poisoned. Casting fire magic works well, especially with a good effect like Quintcast or Limit Break. Ignis's Enhancement can grant Noctis's weapon its elemental weakness. The Spelldaggers from Final Fantasy XV: Episode Ignis also always hit an enemy's weakness. The player can also equip a royal arm, which ignore enemy defenses. The player can character-swap to Prompto and use ranged attacks to stay out of its way. Hitting its tail can be safer than hitting its front, though fighting it head on offers more block and parry opportunities.
