Swords seem ripe for tactical possibilities, but rings seem more personal to me. Here are five rings that might be interesting to your players:
One malady will but darken it, any more rebound on all in sight.
Ring of Flight
Shatter it with a word, and foes, blinded by shards, will let you flee.
Ring of Extrication
Taken off, it transports you to the place you put it on, but the ring stays behind.
The awkward thing will never come off your hand, but when you end, they'll all know how-- family, guild, or clan.
Ring of the Eight States
On each finger it reveals another facet of your nature: slumbering, drunken, fearful, meek, bold, tireless, serene, unswerving.
