Crucible has a max wave?

[Fetito Fazzito]

I have reached wave 110 and then gave up to obtain good loot.

How do I increase the difficulty?

150 wave to "complete"/best loot
after completing 100th you will unlock new diffculty, and one more time for final difficulty,
Aspirant-->Challenger-->Gladiator (same as norm, elite and ultimate sorta)
best loot is ofc after full completion on 150th wave
and once you completed you can increase challenge lvl on "current" difficulty, by adding extra spawn portal (talk option with Crucible master)
there is sort of a "checkpoint-increase challenge option", where you ask to start from later wave (50/100) and supposedly increases "current difficulty" somehow, tho exactly what it's supposed to do i still haven't figured out lol, since monster spawn seems random still

You unlock the next difficulty after completing wave 100.
