Part of Destiny: Nimble
Level 3
Threadling Companion.
Choose a small, medium, or large shape as your Threadling. Instead of your first 2 TotH abilities, you gain the Go for the Throat! and Protect Me! abilities to use with your Threadling. Its attacks count as your own for gaining TotH charges.
Threadlings do not track health or actions, instead act as extensions of your character. You can swap your Threadling during a long rest.
