Ring, rare (requires attunement)
This ring has 3 charges and regains 1d3 expended charges daily at dawn. While wearing the ring, you can take a Magic action to expend 1 to 3 charges to make a ranged spell attack against one creature you can see within 60 feet of yourself. The ring produces a spectral ram’s head and makes its attack roll with a +7 bonus. On a hit, for each charge you spend, the target takes 2d10 Force damage and is pushed 5 feet away from you.
Alternatively, you can expend 1 to 3 of the ring’s charges as a Magic action to try to break a nonmagical object you can see within 60 feet of yourself that isn’t being worn or carried. The ring makes a Strength check with a +5 bonus for each charge you spend.
Notes: Damage: Force
Why is this ring rare? I could easily give this to a level one party and still not break the game due to the fact that it only has up to three charges a day.
6d10 (33) force at level 1? That would one-shot the boss
Pfft, give the Kobold a phase 2. He comes back meaner than ever, breathing fire!
