#im eyeing creaturecodex's commissions for a PF conversion of this beasty as we speak

[monstersdownthepath]

Perhaps predictably, I've found my new favorite obscure D&D 3.5 monster (converted into 5e by this gentleman in the vid).

If you like tabletop monsters as much as I do, I also greatly recommend Dungeon Dad, since I'm showing you one of his videos! He converts monsters from all over into D&D5e and works to make all of them mechanically distinct and interesting, while also going over the history (in and out of universe) of each monster, tactics they may use in battle, and adventure hooks for DMs using these monsters.
