Some of the problems with that:
You still have not discovered a way to find the wizard. This is the important part.
He has Mindsight. He sees you coming.
He is immune to being turned fanatic (Mind Blank).
The wizard has twenty-some off Contingency spells.
He is immune to poison.
And, to top it all off, you took ten levels of a crappy prestige class and the rogue levels needed to enter. Also, you're a drow.
Thanks for playing.
ErhnamDJ, there's no need for the condescension, buddy. I'm rooting for the underdog here, thank you very much, so I already knew it was going to be tough to come up with a workable build. Maybe instead of shooting down ideas you can do something constructive and suggest ways to overcome the issues?
And when we're down to the pathetic point where the biggest advantage a caster has is turning into a fucking giant turtle from an otherwise low-powered splatbook just to gain a surprise round, I'll take 10 levels in a crappy PrC just to DO SOMETHING in the surprise round.
Getting on to the list of issues...
I didn't realize finding him was the biggest problem. But maybe pumping up gather info and talking to his familiar or something would do the trick. The character has the skill points to spare, after all.
I assumed darkstalker would block mindsight, but it seems it doesn't (whoops). Anyone have a way to been mindsight as a non-caster?
Can you give a justification for mind blank stopping a mundane method to make somebody like you? The only thing I'm seeing is if diplomacy is considered a mind-affecting effect, which is a stretch. Even if there is some weird epic level rule about fanatic, we only really need friendly or helpful here anyhow. And like I mentioned, I'm assuming diplomacy works for the challenge, because it pisses me off that a viable method is make ineligible simply by the arbitrary qualification that the characters have a player representing them at the table.
Phaedrus already took care of the contingency argument, though to be fair even if he had 20 contingencies, as long as he loves the character, why would he use them?
The build as presented wasn't immune to poison. It could probably GET poison immunity, though turning into an undead, etc. wouldn't work, since then he wouldn't be a dire turtle, which is apparently the KEY to victory in D&D.
And the race is Half-Elf. Which is really a crappy race as well, but it's not quite drow. And somehow the thought of a half-elf even coming close to beating Mr. Giant Terrapin makes me kinda happy.
