I'd rather they allow me to collect frags for each trial breakthru advancement.

And once you unlock, it remain unlock and you can simply switch if needed.

The diff is you can't estimate what it takes/cost to do skill trial and it's v inflexible.

The RNG roll still feels fine, sure if you want to put some luck into the game.

But its when it comes to the Locking you suddenly realized.

All the Lock that costs, including in purification, is kinda meh after all.

Just make each single roll cost more, and the lock cheap instead.

In fact, make the locks free, and each single roll way exp is better.

A double stacking of cost of Locks upon Rolls makes it complicated.

To the point: penalty is given to those who are unlucky and had to make a choice if to lock way more th*ual.

Imo developers should have put more thought into it.
