Hello, good hunters!
I'm happy to unveil my take on the legendary False Hydra:
If you are a player and don't know what a False Hydra is, do not read further!
Trust me, send this post to your GM if you want, but stay away, you'd be robbing yourself of an awesome experience.

I cranked up the horror and packed it with abilities meant to leave your players questioning reality.
For example: It tears off chunks of its own writhing flesh to bury foes under a torrent of the dead's forgotten memories, or detonates one of its heads to overcome failed saves. Fun Stuff!
I could've piled on even more eldritch madness, but decided against it to keep the stat block from bloat.
Instead, look forward to a lineup of variants down the road: everything from its young wyrmling, scaling up to its ancient colossal form, and maybe even alternative versions.
I'll also be crafting lair actions and environmental effects to make its domain an inescapable symphony of dread.
The artwork is still a WIP from the talented Orfii. I'll put in the final piece as soon as it lands, and knowing him, we won’t be disappointed.

Dive in below and let the False Hydra erase some memories.



And now enjoy all the variants of the Hydra, from wormling to 9 headed ones.



Enjoy!

No idea. What were we talking about again?

Ah, sweet, DM made horrors beyond my comprehension

Oh hell yeah, this is my favorite- Hmm? What am I doing here?

Right the title of the monster is False Hydra (6 Heads), but I made the 6 Heads font transparent by accident! Edit: Fixed!

One of my favorite D&D monsters! I’m not seeing a specified number listed for how many heads the creature starts with. Do we divide the creatures HP by 50 to get the number of heads?
Monkey DM
Yes, of course, there is nothing here. This is a perfectly normal town...

Monkey, you seem to have posted a blank. Did something go wrong? There’s nothing here but your sign off.
