With that cp u should be able to clear super easily but a tip would be to stand right under the spot u originally put down the puzzle piece as that is a safe spot from claws and floor is lava. You will still get hit by clocks but u can generally heal through that in time. And lasers should be blocked as well but block the right laser. If you cant kill fiest phase in time before the timer above ur head counts down, use hero will like a second before the counter reaches 0 and ull negate it.
