Caustic Geneology

You owe your heritage to a particularly corrosive species of ooze and thus have a form that is particularly acidic. You can choose to press your flesh against a non-magical object susceptible to acid and corrode it over the course of one minute. Additionally, you can attempt to occupy the space of another creature that is at least one size smaller than you. A creature that starts its turn in a space occupied by you suffers 2d6 Acid damage, and must make a Strength saving throw. On a failure, its movement speed is reduced by half until the start of its next turn. The DC for this saving throw is 8 + your Constitution modifier + your Proficiency Bonus.
