Is there any published magic item that reduces an animal one size? This is specifically for an animal companion, but could really be used on any trained animal that the party has. Something like a collar, harness, etc.
It would be based off of the Druid/Ranger spell Reduce Animal... but I am looking for it in something other than in wand or scroll form. I understand I could make it myself using the custom magic item creation rules... but did not want to reinvent the wheel if it is already published somewhere. Thanks!
