I really wanted to play a Shadow Blade gish, but neither that spell, Bladesinger or the Blade-cantrips are in the game. There was a mod that added them for EA, but that obviously needs updating.

I probably can't make myself wait until they're updated, so I might make a Dark Urge Gloomstalker Assassin in the meantime. Maybe try adding in Shadow Monk instead of Fighter for a different, less powergamey flavour.
