Is it possible? Just curious.
Until Kelris it’s doable. But for him you need at least 3 players, otherwise when he phases you it resets if no one is left in the room with him.
When i’ve looked at videos at attempts. It looks like if you can 1 shot the mob (with instant cast) you could make it into a portal. There is a good second before it resets.
For Kelris u need at least 2 ppl because portal thing. If u get in portal and 100% u will boss is reseted so someone needs to be outside while u r teleported.
I just solo’d it, As a paldin, i double judged until i landed in a portal. Afterwards I didn’t get telported back into the dream. Killed the boss
