The plot has been fouled, however, by a trio of angels who stole the hydra at birth. It is now bound by magic and secreted away, far from demonic eyes. However, if it ever fell into their hands again...
This month, as a participant in the A-Z Blog Challenge, I'll be writing a post each day (except for Sundays) and letting the alphabet guide my content. Thematically, all of my April posts (at least those related to the blog challenge) will be monster related. Each day, I'll be challenging myself to create an encounter, NPC, location, etc. that features a monster I've never used before in a roleplaying game. Hopefully this will push me to include more variety in my current campaign, and who knows... maybe I'll find a few new favorites.

Fast Healing (Ex) A hydra's fast healing ability is equal to its current number of heads (minimum fast healing 5). This fast healing applies only to damage inflicted on the hydra's body.
Hydra Traits (Ex) A hydra can be killed by severing all of its heads or slaying its body. Any attack that is not an attempt to sever a head affects the body, including area attacks or attacks that cause piercing or bludgeoning damage. To sever a head, an opponent must make a sunder attempt with a slashing weapon targeting a head. A head is considered a separate weapon with hardness 0 and hit points equal to the hydra's HD. To sever a head, an opponent must inflict enough damage to reduce the head's hit points to 0 or less. Severing a head deals damage to the hydra's body equal to the hydra's current HD. A hydra can't attack with a severed head, but takes no other penalties.
Regenerate Head (Ex) When a hydra's head is destroyed, two heads regrow in 1d4 rounds. A hydra cannot have more than twice its original number of heads at any one time. To prevent new heads from growing, at least 5 points of acid or fire damage must be dealt to the stump (a touch attack to hit) before they appear. Acid or fire damage from area attacks can affect stumps and the body simultaneously. A hydra doesn't die from losing its heads until all are cut off and the stumps seared by acid or fire.
