shade of a witch

so im doing the whakawairua tuahau map for the first time

the boss according to wiki was suppose to be merveil's daughter, but greets me is Shadow of a witch



Now the problem, is there any reasonable way to counter her? her righteous fire eats all my life through 85 fire res in less than 2 second and flame surge doing like 3-5k /cast. not to mention she uses lightning warp with prob faster casting and reduced duration so its pretty much impossible to get away from her

any advice would be appreciated ( even though I already died all my portals )

Maybe ranged character + bear traps would help? This game isn't optimized for melee characters...

edit:
oh, never mind, i remembered that it is possible to use lightning warp while in bear traps... :) maybe temporal chains would slow her cast speed? Also you could try using "freeze mine" which always freezes enemies (remember that temporal chains prolongs the freeze effect duration?)
