Tornado’s Eye

This large (6-foot-wide) crystal orb maintains tornado-force winds (see the DUNGEON MASTER’s Guide) around the outside your stronghold at all times. See the description of the hurricane’s eye for how this works.

If you join this item with a hurricane’s eye or a wind-storm’s eye, they can each only function at the level of the weakest item.

Caster Level: 18th; Prerequisites: Craft Wondrous Item, control winds; Market Price: 90,000 gp.
