Staff of the Whale Spirit

Uncommon, Staff (requires attunement by a Druid)
This wooden staff is crowned with a smooth, polished piece of ambergris, faintly glowing with a soft, oceanic light. The staff hums with the ancient power of the sea, and its wielder sometimes hears soft whale calls in the distance while casting spells through it. The staff is imbued with the essence of the ocean. If you are a Shepherd Druid, you gain access to the following Totem option: Whale Spirit Totem. You can summon the spirit of a whale to aid you and your allies. The spirit appears as a spectral whale that hovers in the air, emanating an aura in a 30-foot radius. The spirit lasts for 1 minute or until you dismiss it (no action required). While the spirit is active, you gain the following benefits:

• Protective Aura. Enemies treat the aura as difficult terrain.
• Tidal Force. When an enemy within the aura is hit by an attack, they must succeed on a Strength saving throw versus your spellcasting DC or be pushed back 5 feet or knocked prone (your choice).

Water Jet. The staff has 2 charges. While holding it, you can use an action to expend 1 charge and unleash a powerful jet of water in a 30-foot-long, 5-foot-wide line. Each creature in the line must make a DC 15 Dexterity saving throw. On a failed save, a creature takes 4d4 bludgeoning damage and is knocked prone. On a successful save, the creature takes half damage and isn’t knocked prone. The staff regains all expended charges daily at dawn.
