How to unlock insane trials?

[szili.anna]

Why hasn't the insane trials unlocked even though I finished all the hard ones? What do I have to do to unlock them?

You need to upgrade your Knuckles to level 25 to unlock the first Insane Trial. If you don't know what "knuckles" are, you're not ready for insane trials yet - they'll unlock at a time where it may not take you more than one hour to beat them, if you have the right zodiacs for them.

And since Achievment 267 (Complete first Insane Trial) is after Achievment 264 (Reach Mineral Level 60) you may have another clue to when it gets unlocked :)

I think. I am not so far in the game :)

Generally, achievements are based on progression.

Doesn't stop crazy people like me from unlocking achievements 321-348 before getting #320 (which was the last one before the Tarot update.) And I'm currently missing achievement 385, even though I have 386-413 unlocked.
