Posted Feb 5, 2025New Oni, but still the same idea to play one as a nightmare against your players.

Posted Mar 27, 2025I can't believe the Oni still doesn't have the 'Shapechanger' subtype. I'm definitely headcanoning it for my games

Posted Apr 5, 2025That's because in the 2024 rules there is no such thing as the "Shapechanger" subtype anymore. Any effect that used to target Shapechangers now refers to a creature this is shape-shifted . Shape-shifting is a general game term now, and includes all Druids that are wildshaped, all creatures that were previously labeled as Shapechangers when they aren't in their true form, and creatures under the effects of spells like Polymorph.

Posted Apr 15, 2025I strongly dislike the fact that they stopped telling us what armor a monster is wearing. It makes modifying monsters harder. It wore chainmail before but it's AC is 1 higher now. Why? What if I want to put it in plate or leather? This feels like a slouch into the MMOy 4e monsters (some of which were great, but not because we didn't know what armor it was wearing).

Posted May 3, 2025I think, if it were wearing armor, it would be in it's loot table. I think it's just got natural armor now.

Posted May 27, 2025I preferred it when they could infinitely cast Darkness, plus bonus action invis is too OP. I'll still be using the old version.

Posted Jul 29, 2025the Oni should have blindsight for 15'. When it casts Darkness, its third eye on its forehead opens; and the spell eminates from that eye.

Posted Aug 16, 2025The perfect underling to a hag.
These two sadistic, cruel and frighteningly crafty monsters were MADE to collaborate with each other.

Posted Sep 21, 2025They do actually, if they drop armor as loot that's what they were wearing. If they don't then they don't have any on
