If you are talking about the room which shoots fireballs, I have solved that room with absolutely no rolls needed. There are multiple ways to solve issues in the game.
Did you try conjure water on the burning area? Puts out fires.
Did you try dash through the fire. Only 1 round of fire damage taken that way.
Did you try disarming the traps, there are many so the odds of failing ALL disarms and perceptions is pretty low.
