i recently noticed that ToD rings are annoying when it comes to planning chars equipment, preset bonuses on those rings (and i dont mean the set bonus) are usualy not used as they are same as on other items, example:
Defender of siberys ring: +6 str
Levik bracer: +6 str
it would be great upgrade of those rings if there was a ritual to change +6 stat into other stat and same about +1 exceptional. it would make it possible to "fit" those rings into equipment plans perfectly.
