River Stalker

You are a master of ambushing prey in aquatic terrain, striking swiftly and vanishing just as quickly.

Aquatic Ambush. You can take the Hide action as a bonus action when in water or while partially submerged.

Element of Surprise. You have advantage on attack rolls against any creature you surprise.

Precise Strikes. When you hit with a melee weapon attack against a surprised creature, you may add your proficiency bonus to the damage roll.

> River Stalkers are feared not for their strength alone, but for the silence before their strike — a sudden burst from the reeds, and then nothing but ripples on the water.
