Gloves of Amphibios (Patreon)

Wondrous item, uncommon (requires attunement)

These gloves come in many different colors and meld seamlessly into your hands when you don them. While wearing these gloves, climbing doesn't cost you extra movement, you gain a +1 bonus to Strength (Athletics) checks made to grapple a creature, and any creature grappled by you that is not wearing armor takes 1d4 poison damage at the end of each of your turns.

They worshipped a strange totem: a god of frogs, of all things. I was dubious, too, until I was taken prisoner by the guards. Their grip was like a toxic shock, and suddenly I knew that all gods, no matter how strange, have followers worthy of fear.
