Weaver of All Equations

As a full action, you can devour portions of a creature that has less than 15 hits points or is dead. Negative statuses that would be applied to you specifically from devouring the creature or portions of the creature are nullified. If the creature is alive and reluctant, you must roll a 2D20 + Constitution. The creature is sent to your stomach and you permamently gain spells, and all unique traits of your choice and heal based on its size. You can try up to three times.
Heal: Minor=1d4 + creature's Constitution modifier. Gain up to 1 trait. Small=1d6 + creature's Constitution modifier. Gain up to 1 spell or trait. Medium=2d6 + creature's Constitution modifier. Gain up to 1 spell and trait. Large=4d4 + creature's Constitution modifier. Gain up to 2 spells and traits. If its the whole creature then gain all spells and traits.

At Higher Levels. When you cast Weaver of All Equations using a spell slot of 2nd level or higher, the hit point threshold increases by 1d6 for each slot level above 1st. At the 10th level the gain of each effect via consumption increases by 1 for each level above the 10th. At the 15th level every spell or trait that can be gained from Weaver of All Equations that cannot be currently used or equipped due to maximum capacity can instead be applied to a pre-existing feature of yourself with the corresponding value of the spell or trait.
