Dancing Scimitar and it's not close. Every solo or buddy Mage book has at least one, and I question whether or not I should add one to every other Mage. If a book has a melee weapon, it almost always has a Scimitar too. It's that good.
Regrowth Belt would be next. It's also a top Dissolve/Explode target, often prioritized over a chest piece (unless that chest piece gives a relevant damage type -X).
As for theme or art or fun combos, I'd go with Eye of Bael. My curse Warlock has multiples to distribute via Battleforge onto the opposing Mage. Fun times!
