In-game description
"Wand of Wonder Only those with a gambling streak dare use this wand in battle. When triggered it is, at best, unpredictable and, at worst, suicidal. The whimsical mage Malimak created it as a gift for a rival, though more as a prank than with hurtful intent. The recipient's reaction is not known, though Malimak relocated shortly thereafter. It should be used with caution, or not at all."
