Sticky Boy

You have learned how to harness the inner stickiness within all creatures. Your skin becomes sticky to the touch, like glue. You gain a climbing speed equal to your walking speed, and while climbing, you gain advantage on any saving throws against effects that move you on a failure. You also learn the first level spell Grease, and can cast it once per day without a spell slot, as you have learned how to imbue objects with your innate stickiness.
