Mace of Kobold Golfing (3.5e Equipment)
From D&D Wiki
Mace of Kobold Golfing: It appears to be a normal +1 Heavy Mace. Nothing special, nothing happy. But, upon hitting a kobold or another creature the same size or smaller with it, the effect activates. It sends the unfortunate subject up to 3d6×10 feet in the direction that they were hit. If the creature is sent into a hole, it explodes into a shower of random coins. If the adventurer sends his subject into a target, have him roll a ranged attack. If the attack is successful, reward him with a shower of coins from one creature, and a shower of cookies from the other. Up to 3d6 worth of gold may be discharged in any form that the DM finds acceptable. The struck target discharges 1d6 cookies. Mmm... cookies...
