Wave 10 Ultimatum - Must be completed 3 times?

I finally managed to clear a full 10 wave ultimatum, but instead of being able to ascend, I'm only seeing a locked tower door for the Trial Master requiring "three fates".

I had 1 in my inventory, I placed it in the impression on the wall (jigsaw puzzle type of lock). I'm assuming you have to beat ultimatum wave 10 3x total to have the "three fates". Anyone know?

Yes, you need 3 fates to have a shot at the final trial.

Let me guess, the final trial is a Maven witnessed Uber Elder, with Trialmaster and every possible Ultimatum negative modifier on you and maxed out.

Am I right?

Not only do you need 3, but you can need more than 3 if you manually collect duplicates by bad luck.

Wtf??

Anyone know if Trial of Sekhema requires some BS keys like this for the final 7-8 ascendancy points?
