The SendingStone review

The Hydra is a formidable creature, boasting impressive stats including high HP and a challenging CR of 8. Its natural armor and passive perception of 16 make it difficult to take by surprise, and its massive size and multiple heads make it a fearsome opponent to face in combat. However, its low intelligence and charisma stats suggest that it may not be the most strategic or diplomatic of creatures. Despite this, the Hydra remains a popular and iconic monster in the D&D universe, and is sure to provide a thrilling challenge for any party of adventurers brave enough to face it.

Hydra is D&D (Dungeons & Dragons) 5th edition content, but other TTRPGs may have their own version such as a Hydra Pathfinder edition. Want to use Hydra in a VTT (virtual tabletop)? Try out SendingStone for free today!
