Trials of sekhema/chaos temple

Im stuck at my third ascension...

For sdome reaon my trial of sekhema coins make me eligable for ascension, but chaos temple coins never do even tough they are at same level.
Am i forced to do it in trials of sekhema?

Also do i have to do al l3 stages to get ascension or im missing something?

I just got al lthe way to third boss and lost all honour by him jumping around and a trap.

Do i REALLY have to do al l3 stages of those friggin rooms that take HOURS just to make another attempt on this last boss?
