Arkhandus
First Post
He could be a feral human. Shocked no one has mentioned this. You automatically become a monstrous humanoid... get a ridiculous number of bonuses.. and all for +1. Mind you.. it's from savage species... but still. If your DM is dumb enough...
He said core 3 books. Feral template isn't core.
A Wand of Darkvision would cost 2,250 GP at 3rd-level caster, getting you 60-ft. darkvision for 3 hours with each use. The spell is touch-range, so the wand's user doesn't have to be the one it's cast on. And since it's a Ranger spell as well as a Sorcerer/Wizard spell, your proposed build would be able to activate the wand as long as you had at least 1 level of Ranger. The Wand should hold you over until someone in the party has the ability to cast the spell directly (and is willing to spend slots on it each day) or until you can afford Goggles of Night (which are in the Dungeon Master's Guide).
Shadowdancer is another core prestige class that grants darkvision, but it would have to wait until something like your 9th character level or later to get that class feature.
