AREA: WALL OF ICE

Duration: 10 turns

AoE: 9m (30ft) line

A solid wall of ice pillars that blocks movement and line of sight. Creatures in its path when it appears take 10d6 Cold (Dexterity Saving Throw for half).

• When a section of the wall is broken, it leaves a cloud of frigid air.
• Creatures inside take 10d6 Cold damage per turn.
• Constitution Saving Throw (DC 16) for half damage.

When to cast Wall of Ice

Cast it on top of the enemy line. Anything standing in the wall’s path takes 10d6 immediately, and then the wall is between them and you. Enemies who smash through it are standing in a freezing cloud that does another 10d6 a turn.

Use it to split a fight. The wall blocks line of sight, so the archers and casters behind it cannot target your party, and the AI mostly either paths around or tries to break through. Both options cost them turns.

It is 9m long, shorter than Wall of Fire, and it is Concentration. The damage has fixed save DCs (15 for the wall, 16 for the cloud), which means your spell save DC gear does not help it but also that it stays reliable without it.

Cold is resisted by a fair number of late-game things and the cloud damage counts as non-magical for resistance purposes. Against fire enemies and devils it is superb. Against ice things, not so much.
