A bestiary of cultivated horrors, compatible with 5.5e and 5e

Sixty-seven creatures for a world where the things people grow have started growing back. Twelve species of sentient vegetable across three stages of life, the ecology that lives alongside them, the fey who tend them, and the thing they are all cuttings from.

Every stat block is compatible with 5.5e and 5e. It is tuned mainly for the power level of 5.5e, so some creatures may feel stronger than their listed challenge rating in a 5e game.

Use as much of it as you want. A single creature is a roadside encounter. One stage is a set of random encounters for a tier of play. A group of them is a one-shot. All three stages, in order, is a campaign.
