Drocoliches in the 2024 Monster Manual received their own dedicated stat block.

I am pretty happy that there is a unique stat block with lair & legendary actions available. But my main issue with this is it appears to only be based off of a adult dragon based off the 225 HPs.

A dragon seeks out this form typically to extend its time on the world so I'm a little shocked they didn't include an Ancient version. Ancient dragons typically have at least 450+ hps and while you can just increase that that's not the only differences between adults and ancients.

Also I am a little disappointed that they didn't include a Chromatic and Metallic version. (I know it's not likely to happen but it's possible)
