Item: Super Crown, transforms any creature or character into an athletic princess that can hover for some reason, as illustrated here by a young Myconid maiden.

(Source, as if you could be on Tumblr right now and not know.)

The resultant hybrid princess-creature also possesses a preternatural
charisma that seems to compel characters of artistic persuasions to
render commemorative portraits; roll Will save against the portraits
being of an overly salacious nature. If any adventuring parties out there happen to slap a Super Crown on, say, a Shrieker, Gelatinous Cube, Wolf In Sheep’s Clothing, or other dubious creature, and are able to obtain any of these portraits (the less-salacious ones), your humble blogomeister would be willing to display them for the edification and appreciation of the adventuring community at large.

Item: Cactus Jacket; while it appears smooth, any creature trying to engage the wearer in a grapple attack will be stuck full of spines, dealing Puncture damage equal to the grapple check (e.g. they roll a 6 plus a +2 modifier = 8 points of damage)

Item: hovering, gently throbbing Icee; does not allow true flight, just sorta switches off gravity for the user and their equipment for 12d12 rounds. The effects are accompanied by a mild nausea as your organs deal with the lack of gravity.

Item: twenty-use tub of Frog-Tech™ 100% Natural Genetic Frog Fibres Osmotic Acceleration Technology. For every scoop consumed, creatures get once use of a frog power for 2d6 hours:

  1. Greater Jump
  2. extending sticky tongue that can grab things
  3. great bulgy eyes with improved peripheral vision
  4. amphibious (able to breath comfortably on land or underwater) but as a result becomes extremely uncomfortable when not allowed to stay moist
  5. become brightly colored and exude a viscous poison/hallucinogen
  6. become brightly colored to suggest to enemies that they exude a viscous poison/hallucinogen, but don’t actually do it
  7. yell loudly once per round whenever aroused
  8. enlarged mating claspers

Item: Gator Gaiters, slip on over standard shoes and strap on using the chains. Thanks to the Alligator hide (for some reason there’s no gators in Grayhawk, so see Crocodile), you gain the animal’s power to restrain through grapple checks. Plus you can kick people with the spurs
