I'm happy that they at least explained how the fuck MC got attached to that dwarf chief so quickly and so hard - daddy issues.
And I also thought that the summoning made him change physically, but I was sure he would be teenager/shota. Ghost is fine too, I guess. Maybe it's even better that way? He's quite unique now after all. If he can phase trough the walls then it would be even better for him to check buildings or mines.
And yeah, always double tap your enemies. But I will give it a small chance, it's necromancer after all. He may have resurrected himself into some sort of undead (lich myabe?)
