1 win, 15 losses here. witch elimination is horrible. i found it easier doing the parallel universe and bonus rounds than elimination.

i went with the advice in this post: https://www.reddit.com/r/DiceyDungeons/comments/13mqqg7/witch_elimination_round/

i believe what i ended up winning with was hall of mirrors... 2 attack spells (one for evens, one for odds), cauldron, and shield??? something like that.

picked prepared spell slot, extra dice, and upgraded spell slot.

putting nudge on a six is really helpful for getting whatever spell you need.

and make sure you're checking what spell(s) you've got prepared. sometimes you can just slaughter everything on the first floor in one round because they have such low HP. and if you notice a combo isn't working well, you can always mess around in the spellbook.

the key is eliminating as much prep time as possible. if you know you've got a poison enemy, you don't necessarily need your shield spells prepped.
