I can tell you this though from the videos I saw from people on TikTok where they got the crystal to drop and from my personal experience if you do the first boss and then you do the final boss and then you do the first encounter (no feats) it seems like the drop rate is slightly higher.. It seems like that's how most people got the crystal to drop not just simply just do a full rhyme but just do portions of it.. Plus don't listen to the idea people say you complete the dungeon once per week and then you just can find the same encounter Uber and Uber that is a myth it's not true you have to complete a full run to get it to drop it doesn't have to be in order but it has to be a full run..

You can do it on normal and I know that because I have the crystal...... after 30 runs and carried 12 players it dropped lol.

Such a great mov.....nope, wrong idea. My bad.

I got mine on a regular run. Just took multiple runs. You also (I think) have to do complete runs. 3 checkpoints.

The crystal drop is akin to the secret chest drops, except it requires all 3 encounter completions [b]in any order[/b] (the secret chests each require their respective previous encounter be completed to be looted).
