Winter's Stronghold

Cooldown: 60 hours

Syntax: cast "winter's stronghold"

This powerful working of Wintertide summons forth barricades of ice to construct a fortress centered on the caster but spanning many rooms. This stronghold of winter will cause all cold damage within it to be increased, and spells not of the sphere of water will occasionally fail within its walls. Those trapped in the fortress may find it difficult to leave through mundane means until the ice melts; those with the ability to pass freely through doors will be left unhindered. A certain minimum amount of space is required for this working; if not present, it will fail.
