(Dedicated 1 EI Slot for this Effect, even though it’s not an actual magic item)
Taggable “Strong Link” to Paranet Relay Spell, to other pre-determined rings
Acts as a symbolic link to about two dozens other rings for a minor thaumaturgical “message relay” ritual. The other rings would be able to be a symbolic link with the relay ring, but not with the others.
(She melted the other rings using Sonic welding-based spells just enough to melt plastic from each individual rings onto the ‘relay’ ring, giving her a solid magical channel even though they are cheap cracker-jack decoder rings.)
