You create a wall of water on the ground at a point you can see within range. You can make the wall up to 30 feet long, 10 feet high, and 1 foot thick, or you can make a ringed wall up to 20 feet in diameter, 20 feet high, and 1 foot thick. The wall vanishes when the spell ends. The wall's space is difficult terrain.
Any ranged weapon attack that enters the wall's space has disadvantage on the attack roll, and fire damage is halved if the fire effect passes through the wall to reach its target. Spells that deal cold damage that pass through the wall cause the area of the wall they pass through to freeze solid (at least a 5-foot-square section is frozen). Each 5-foot-square frozen section has AC 5 and 15 hit points. Reducing a frozen section to 0 hit points destroys it. When a section is destroyed, the wall's water doesn't fill it.
Choose a willing creature that you can see within range. Until the spell ends, the target's speed is doubled, it gains a +2 bonus to AC, it has advantage on Dexterity saving throws, and it gains an additional action on each of its turns. That action can be used only to take the Attack (one weapon attack only), Dash, Disengage, Hide, or Use an Object action.
When the spell ends, the target can't move or take actions until after its next turn, as a wave of cold sweeps over it.
For the duration, you understand the literal meaning of any spoken language that you hear. You also understand any spoken language that you hear. You also understand any written language that you see, but you must be touching the surface of which the words are written. It takes about 1 minute to read one page of text.
This spell doesn't decode secret messages in a text or glyph, such as an arcane sigil, that isn't part of a written language.
A hail of rock-hard ice pounds to the ground in a 20-foot-radius, 40-foot-high cylinder centered on a point within range. Each creature in the cylinder must make a Dexterity saving throw. A creature takes 2d8 bludgeoning damage and 4d6 cold damage on a failed save, or half as much damage on a successful one.
Hailstones turn the storm's area of effect into difficult terrain until the end of your next turn.
At Higher Levels: When you cast this spell using a spell slot of 5th level or higher, the bludgeoning damage increases by 1d8 for each slot level above 4th.
