I was going through some of my gaming stuff and found a sheet of paper listing several magic rings which had been recovered from a hoard of crawling claws. The notes indicate which of the PCs ended up with which rings, but I don't recall seeing any of them used. Perhaps they will find a home in your game.
Source is not me.
I do not know if I came up with these myself or if they are from some other blog. If the latter, I would guess
d4 Caltrops. A quick browsing suggests otherwise. Maybe I tapped into the greater cleverness that directs magic item creation for these games we play.

A silver band with large pearl that kinda looks like an eye. Eyeball gem can detach, as a rolling Wizard's Eye. Radiates Divination magic.
A ring of polished silver that glints in bright light. Wearer's appearance is altered favorably in twilight. Radiates Illusion magic.
Made of intertwined gold and silver bands, with a scowling face on it. Causes the wearer to sneeze in the presence of true dragons. Radiates Divination and Transmutation magic.
A warm gold band, both in color and temperature. Magical flame heals wearer instead of harms; magical flame cast by wearer ALSO heals. Radiates Transmutation magic.
A simple wooden ring, made of polished oak. Wearer can converse with Plant-based monsters (slips into trance, uses weird telepathy, turns all hair a vibrant green that sprouts small white flowers in the spring). Radiates Divination magic.
This ring is a hard, lightweight material (plastic). Children are unable to tell falsehoods to the wearer. Radiates Enchantment magic.
Verdigrised copper band, that feels cool and damp. Wearer is kept dry even in the fiercest rainstorm. Radiates Abjuration magic.
This tarnished silver ring is greasy to the touch. Its wearer is invisible to Shadow. Radiates Illusion magic.
This ring in made of polished bone and loudly goes 'snicker-snack' when giants are near. Radiates Divination magic.
