Wild Shape. You can use your action to magically assume the shape of a beast that you have seen before with a CR of 1/2 or lower that does not have a flying speed. You can use this feature twice. You regain expended uses when you finish a short or long rest.

Symbiotic Entity. As an action, you can expend a use of your Wild Shape feature to awaken those spores, rather than transforming into a beast form, and you gain 4 temporary hit points for each level you have in this class. While this feature is active, you gain the following benefits:

• When you deal your Halo of Spores damage, roll the damage die a second time and add it to the total.
• Your melee weapon attacks deal an extra 1d6 necrotic damage to any target they hit.

Halo of Spores. You are surrounded by invisible, necrotic spores that are harmless until you unleash them on a creature nearby. When a creature you can see moves into a space within 10 feet of you or starts its turn there, you can use your reaction to deal 1d6 necrotic damage to that creature unless it succeeds on a Constitution saving throw against your spell save DC.

Fungal Infestation. Your spores gain the ability to infest a corpse and animate it. If a beast or a humanoid that is Small or Medium dies within 10 feet of you, you can use your reaction to animate it, causing it to stand up immediately with 1 hit point. The creature uses the zombie stat block. It remains for 1 hour, after which it collapses and dies.
