The Thunder Bagua is a silver ring with the pattern of an emerald dragon inlaid into it. When wearing this ring, you may expend one level 3 or higher spell slot to surround your body in a ring of 8 orbs of lightning. Every turn after this until all orbs are expended, you may use one bonus action to fire up to three of them at a creature within line of sight. Each orb ignores all armour and does 2d8+4 force damage.

Notes: level 5 or higher full-caster.
