Pick a race other than Fungus. You take on the form and size of that race, but you do not have access to any of their racial traits.

Add +1 to your Wisdom stat, and add +2 to either your Constitution or Dexterity stats.

You have a resistance to necrotic damage, and cannot be poisoned or put to sleep.

You cannot take a long rest. When at least one other creature within 30 feet of you finishes a long rest, you may consider this the equivalent of you finishing a long rest as well.

Whenever your hit points reach zero, you may detach your Fungal Core from your body. As a Fungal Core, you only have 1 hit point, 5 AC, and a movement speed of 15 feet. In addition, the only action you can take on any given turn as a Fungal Core is Spore Scatter, an attacking action that deals 1d8 necrotic damage + your DEX modifier.

So long as you remain within 5 feet of your host’s body, your host can be targeted with any action that restores hit points so that you may be “revived” with the amount of hit points your host was healed for + 1. Alternatively, taking a short rest will allow you to return to your body, restoring 1 hit point to yourself. 

Upon reaching your 10th level, you may choose up to two racial traits from your host’s race and gain those traits yourself. You cannot use these racial traits if you are a Fungal Core.

After successfully landing a melee attack, for your bonus action, you may roll a 1d6 die. You must perform the action as indicated by the result from the list below as your bonus action.

1. Make a melee attack to your nearest opponent.
2. Perform the Disengage action.
3. Make an Unarmed Strike against your nearest opponent.
4. Become prone.
5. Perform Spore Scatter, dealing 1d8 necrotic damage + your Dexterity modifier to all creatures in a radius of 30 feet.
6. You do not have a bonus action this turn or your next turn. Instead, you may use four bonus actions during your turn after your next turn.

You lose this trait upon reaching your 10th level.
