Why, that's a Yuan-Ti Rampant!

The final comments are in from last week's "Weekly What the Heck". The result is the yuan-ti rampant, a fairly disgusting reptilian thing that gestates inside a humanoid host before bursting out in a whirlwind of acid and nasty pointy teeth.

I'd like to thank Ripper, d7, joeskythedungeonbrawler and Scott (with special thanks to Ripper for the name) for their ideas, all of which have been mashed together to create:

Yuan-ti Rampant

A yuan-ti rampant is created by a ritual known to the yuan-ti malisons. It is usually performed on snaketongue cultists, implanting the rampant seed in them which gestates and eventually hatches into a completely snakelike creature.

Yuan-ti Rampant Tactics

A yuan-ti rampant whirls around the battlefield with spinning frenzy, changing targets as often as possible to spread its poison damage around. It tries to stay adjacent to multiple enemies at all times so its acid blood will catch as many targets as possible.

Yuan-ti Rampant Lore

A character knows the following information with a successful Nature check.
DC 20: A yuan-ti rampant gestates inside a humanoid, gradually transforming it into a fully reptilian creature. In the final stage of gestation the few remaining vestiges of mammalian tissue are shed violently.
DC 25: The yuan-ti rampant has acidic blood that burns those who dare to harm it.

Is the rampant ritual a blessing or a curse? Depends on the recipient's point of view, I guess...
