With a peaceful gesture and murmuring word, you calm the water in a 60-foot cube centred on a point within range for the duration. In the area, a tumultuous stream becomes swimmable, a stormy ocean gains a moment of reprieve, and the effects of water-based spells of a level equal to or lower than this spell, such as the riptide spell, are prevented and 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.
