I'm using smoldering sky, ultimate, and sea daughter (5 tp a tic regain... i definitely wouldn't use this if you plan to melee.. for the most part in abyssea I'm farming upgrade items and +2s with my ls). My numbers are a little lower than Nacht since I'm taking one less damage atma (around 4k on trash mobs, somewhere between 1-3k on NMs depending on their tier).

Definitely use Nacht's atma config if you plan to not wear vulcan's staff (in my experience you lose around 700 damage taking vulcan's off).
