Great Wave of Talismans

4th-level • Evocation (icy paper)
Casting Time: 1 action
Range: 60 ft
Components: V, S, M (sheaf of sigils)
Duration: Concentration, up to 10 minutes
Save: DEX (for passage damage)

You raise a wall of fluttering, silver-blue sigils in a looping wave up to 60 ft long, 20 ft high, 5 ft thick. The wall is opaque and heavily obscures what’s behind it. Attacks that pass through it are made with disadvantage.

A creature other than you that moves through the wall takes 3d8 slashing or cold (your choice when cast), DEX save for half. If the wall would appear in a creature’s space, it is shunted to the nearest empty space and takes the passage damage.

At Higher Levels. Damage +1d8 per slot above 4th.
