Earthseed Symbiote

Earthseed Symbiote: You can manifest a protective mud symbiote that lives within the sigil. When you are hit by an attack roll, you can use your reaction to concentrate the mud symbiote to the threatened part of your body for a moment. You are granted a bonus to AC equal to your proficiency bonus against that attack roll, potentially causing it to miss. You can use this reaction a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

In addition to defensive capabilities, the symbiote can bleed through your clothing to act as an appendage. While not able to articulate, the appendage can hold up to half a pound by keeping the item suspended in a state of constant falling.
