idk if you guys know this yet/this has been posted before but
there's a way to farm the monsters at the top floor for the trials! this is esp useful for the crystal dragon on the top floor in the trial of light bc the crystal scale is needed for a few items but it's a rare drop, not a bounty drop.
so what you do is:
-save at the floor right before the top one
-go up and beat the boss on the top floor!! DON'T SAVE AFTER THIS
-go home and sleep
-go get killed somewhere lol if you have one of the creator/god level quests active it's pretty easy to get killed by any of those monsters. I like to use the tailor one bc it's really close to the terra nimbus house
-when asked to continue click start from last save!!
-you should respawn at the floor before the top one in whatever trial you're doing, and the boss will have respawned on the top floor bc you slept! you can now skip all the floors before the top one and go straight to the boss!! all of the treasure chests should have respawned as well!!
-repeat from the first step!
hope this helps someone!!
