While attuned to this magical ring the wearer's ability to cast spells is sharpened and focused. All of your spell casting is much more difficult to interrupt with Counterspell. For the purposes of Counterspell, against the wearer’s casting, all spells including those of third level and lower, are subject to a DC of 19 instead of a normal “DC equals 10 + the spell's level”.

The second power this magical ring bestows upon its wearer is the ability to make their spells more powerful. The attuned wearer may choose to use one or more charges to increase the spell level of a cast spell. The caster uses their spell slot normally and then may increase that with charges without needing to use or normally be able to cast the spell at a higher level. A caster may also normally cast a spell at an increased level and then increase it further with this ring. If a spell gains no benefit from being cast at a higher level, no charges are expended and no benefits are conferred.

To increase a spell level by one level, one charge is consumed. To increase a spell casting level by two, two charges are expended. To increase a spell casting level by three, four charges are consumed. 

This ring can carry up to six charges. When found, it contains 1d6 charges. It gains 1d4+1 charges after a long rest.
