Calm Waters

With a calming gesture and soothing Aquan word, you still the water in a 60-foot cube within range. In the area, a tumultuous stream becomes swimmable, a stormy ocean gains a moment of reprieve, and the effects of the riptide spell and similar water-based spells of an equal or lower level are suppressed.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the level of water-based spells suppressed by this spell increases.
