D&D has a fine tradition of bizarre, useless magical items. Here's a collection bizarre, slightly useful ones with non-obvious applications:
- Sling Bulettes
- These smooth stone spheres look like normal ammunition for throwing from a sling. Once launched, they transmute in mid-air into a landshark. It is fully alive, and rather angry about having been freeze-dried and stored in your backpack. It is advisable to leave the area before it is done taking out part of its anger on the target of your sling, as it still has more anger left.
