Interlocked cache

Hinged and interlocking, numerous slats of wood overlap and overlay to give an interlocked cache its lock and form. Each finely grained piece fits with its brothers to hold the whole together, creating a tight series of seams through which nary a chink of the contents within can be espied. Interlocked caches are usually garnered from Logosmas stockings, globes, the Wheel of Fortune, and similar promotions.

A cache may be opened for a random talisman piece. One must specify the talisman set that it comes from, but not the talisman. Some caches reward minipets instead, in which case the collection type then must be specified.

Commands:

OPEN CACHE to see what sets can be opened for
OPEN CACHE FOR <setname> to open the cache and receive a talisman piece
