Magic Item- The Blessed Ring: Crafted from silver and usually set with a religious medal. When worn by a Cleric of Good alignment it allows its wearer to cast Cure Light Wounds once a day at their level of spell casting. Further, it grants a level-based bonus to any healing or curing spells cast by its wearer that restores hit points. This bonus is +1 at 1st level and increases by +1 for each additional 2 levels (i.e., +2 at 3rd level, +7 at 14th level). At DM's discretion a Blessed Ring may grant its healing bonus to Religious Brothers, Paladins, Rangers, or other Good-aligned classes capable of casting Clerical spells.
Blessed Rings are obviously useful and a direct example of my fondness for items that grow with characters.
