Hex Bard

Just an old rounder:

Decent armor class.

Insane damage with the resonance stone and 4 attacks per turn in tactician or lower modes.

Control spells as bonus action in late game.

Short rests with bard actions, refreashable by traveling between zones.

Infinite gold with warlock from level 1.

It will not carry your early game and its best past level 9 and after picking the resonance stone in the end of act 2, but is perfect for dialog, “trading” and getting late game bosses to surrender their turns and lives.
