I have an item that makes it so I have a chance to summon my wraiths as flame wraiths.
If I re-summon until my wraiths are fire wraiths, then zone it doesn’t always preserve what element they were. So if I had two flame wraiths, I may zone in and have 1 flame, 1 not, or 2 not, etc.
Not sure if this is intentional, or a bug exactly.
I am also experiencing this bug. My Pyre Golem doesn’t change elements, so my Wraiths shouldn’t either. It is getting very tiring swapping on idols to help respawn my wraiths as fire, then swapping back to my normal idols.
