POUCH OF HOLDING
These apparently normal leather or cloth
pouches are found in groups of 3-6 (1d4 + 2)
attached to a belt. Each pouch can hold 100
gp (or ten pounds weight) as if it were but 1
gp (or a tenth of a pound). However, nothing
larger than 1 x 2 x 3 inches can fit into
a pocket, and the maximum cubic volume
capacity for a pocket is 3 x 6 x 12 inches.
(Thus, vials of holy water would easily fit,
but a dagger or wand would not, in most
cases.)
