The Great Trial

The Great Trial is a 5e adventure for characters starting at 7th level and ending at 10th level. It's a dungeon consisting of three levels, where the first level is the lowermost one and the last is the uppermost one:

The first level features vicious traps, puzzles, and combat;

The highlight of the second level is a labyrinth with a construct Minotaur — the Minotal — and an iron wyvern, both original creatures;

The last and uppermost level is actually a jungle-like demi-plane filled with dinosaurs in an open-world format.
