During our last session, a bunch of players noted the lack of otter-related magic items and an interest in there being some.
So I'm working on some now.
Amulet of the Otter
Wondrous item, uncommon (requires attunement)
While wearing this amulet, you gain the ability to slide. When you take the Dash action, the increase in speed you gain is equal to twice your speed. You also gain advantage on Strength (Athletics) checks made to swim.
Staff of the Otter
Staff, rare, (requires attunement by a bard, druid, ranger, sorcerer, warlock, or wizard)
This staff has 4 chargers and regains 1d4 expended charges daily at dawn.
Spells. While holding this staff, you can use an action to expend 1 charge to cast one of the following spells from it, using your spell save DC: grease or Tasha's hideous laughter.
How do these look?
