race features:
Born with Gills You can breathe underwater
Natural Resistance You gain resistance to poison damage, and you have advantage on saving throws against getting poisoned
Adhesive Secretion You have a level of control over your pores. You can use a bonus action to secrete an adhesive ooze. You can use an action to apply this ooze to an object or attack a target. When a target fails a dexterity save to avoid getting oozed they move as if through difficult terrain. The target must succeed a DC 13 dexterity saving throw to lose the effect.
Slippery Secretion You can exploit the same control of your pores to coat your entire body in a slick coating. This takes a full action and lasts for 10 turns. All melee attacks against you will be made with disadvantage. This can be done once per short rest.
