At the peak of 3rd Origin Mythic Class, Magnar matched Neil's own tier in terms of raw class standing and was genuinely useful in combat at the level they had been operating at recently, the combination of their fighting styles having developed over enough shared encounters that coordination was automatic rather than directed.
But poison was Magnar's weakness in a way it was not Neil's.
A realm where the air itself was toxic to non-native organisms and the creatures were built around venom as their primary offensive and defensive tool was not an environment where Magnar would last long regardless of his strength, and bringing him in would mean spending most of his attention managing Magnar's exposure rather than hunting, which defeated the purpose.
This one he would go alone.
