Cryonis

Choose a 10 foot square of water you can see within 120ft of you and spend an action. A 14ft tall pillar of ice rises from the surface of this water remaining stationary even if the water is moving. The pillar persists for one minute, until it takes any fire damage, or until you destroy it as a bonus action. If creating a fourth pillar the oldest of the other three will be destroyed. You must use both hands to activate this rune or destroy it.
