Why precisely this emerald encrusted ring exists is a bit of a mystery.  Once per week the user may concentrate on the ring for one minute and create a toad to their specifications as long as it fits within a 1 foot cube.  It may be either an existing species or an original creation, but must adhere to the basic premise of a non-magical toad.  The creator of this toad can specific it's appearance, but it's basic stats are that of the frog, with the single exception that if the creator wills it, they may have a poison.  This poison damage is only applied on consumption or otherwise being applied internally to a creature.  The creator of the toad may specific the potency of the poison at creation in a number of d4s up to 5d4.

Harvesting the poison is a difficult proposition, requiring a dexterity check of 14 if the toad is dead or 17 if the toad is alive.  Failing this roll results in the one attempting to harvest the poison receiving the damage.
