A fun, do-it-all type 28 point build. Not at all useless after reaching higher levels (due to high haggle skill, high UMD, decent trap and heal skills).

DPS lower then rogues built for pure DPS, but that's o'kay with me.

Providing a wide-variety of functionality and alert / twitch gameplay is the intent here.

Currently planned up until level 18 at which point Assassin II is trained, giving 12 Rogue / 6 Bard.
Last two levels easily could take a lot of different paths depending on individual desire to better min/max the builds core abilities.
