Cold Craft

You are adept at wielding cold magic. You create one of the following effects within range:

• You create a block of solid ice no larger than a 1ft cube in space you can see within range. If created at a height of greater than 50ft, 100ft or 150ft, the cube deals 1d4, 2d4 or 3d4 damage respectively to whatever it lands on.
• You target a point no larger than 1ft square on a creature. That area of the creature becomes encased in 6 inches of ice. The creature takes no damage. If the creature is bound by the ice to a surface, such as encasing it's foot to the ground, it becomes restrained. The ice is considered an object with 5hp that is vulnerable to fire.
• You create a cold breeze in an area no larger than a 10ft cube. The breeze is considered calm but powerful enough to snuff out a small flame or campfire or sweep papers off a desk.
• You freeze a section of water, creating a small ice berg no more than 5ft square and 6in thick. The ice is thick enough to walk on.
