how do you find someone who cant be found?

[shadyizok]

Hmm, options could be to let the spellcaster after they got shanked by the super-invisible PC for the first time to cast true seeing, if still not able to see to cast glitterdust (maybe widened). But if none of those strategies work, (the hide check is still 60 even after glitterdust) try changing your tactics.
Apperantly your PC has spent lot's of power and money and effort in becoming unseeable, so it's only natural to not be able to see him by expending only a fracture of the same power/money/effort.
So you can't see him? Ok cast a fog spell. Suddenly your PC lost it's advantage (everybody is unseeably from more than 5 ft) ow and to boot his sneak attack is off (can't sneak attack a target that has concealment).
That should at least even the odd's. If your NPC's have any knowledge of this ability of their foe then they could even have made a strategy involving this tactic.
Or just be immune for sneak attacks. Who cares that he's invisible when he's dealin 1d6+2 damage a round at lvl 19.
Or have spells/effects that hurt anyone attacking the caster.
Try to think outside the box, not just for simple easy ways to counter your PC's effort. Remember: he's a one trick pony.

Idea: Love's Pain, BoVD.

Mindrape someone into loving your target, then cast Love's Pain on your minion.

stream of the sky- Yes, I think its in the libris mortis.
Irdeggman- Good very mundane ideas, which I have been thinking about. The feat Darkstalker protects against blindsight, blindsense, and I also think tremorsense, scent, all of that stuff.
Herzog- I am not familiar with touch sight. Where can I find it?
FEADIN- I am not sure if he has hide in plain sight, i dont think so. Yes, that is true.
ShadyIzok- Yes, he has invested feats, skills, money, all to be very difficult to find. He also has some nasty weapons, and if you can be sneak attacked he can deal some serious damage. Yes, fog cloud, so basic so simple, thank you. You have just given me several ideas on how to weaken him.
dandu- I am not familiar with mindrape no loves pain nor what BoVD stands for. (of course i will know probably know the long form)
Thanks again everyone. Appreciate the help.

Mindrape is an SpC spell that allows you to reprogram a target's memories.

Love's Pain is a spell that damages the target's loved one.

Book of Vile Darkness is a 3.0 book for evil characters.

Touchsight. It's a psionic power.

I lol'd.

And a fancy and ridiculously ineffective way to try to find him would be using Lore of the World utterance to ask to the floor if it has 'seen' him.

1) Sneeze powder and lots of it.

2) Lots of caltrops and Grease spells.

3) As you're leaving the room, drop in a Decanter of Endless Water and seal the room- with you keeping the stopper.

3a) Instead of Decanter, throw in a hive of wasps.

4) Cast Transmute Rock to Mud followed immediately by its opposite.

5) Cast Shrink Item on as many bear traps as you can get your hands on, then scatter them. Then say the command word that undoes the spell.

And if he stays alive, throw him to the awakened Tarasque. Just for fun. No offense, but your friend/player sounds like a munchkin, or at least an uber-power-gamer. You should have anticipated where he was going and, say, house rule out some of his choices. Well, I guess that is a lesson learned ^^

ok, this is my first post: be gentle.

What about anti-magic fields? Wild magic?

I tend to let my players do what they are capable of doing, so if I did allow this I would probably have to suffer through it. But, wouldn't he eventually get tired of sniping while everyone was having fun knee deep in battle?

You could also just have NPC's occasionally see him. You are the DM, can't you make that ruling and not tell the PC's how? That create tension and gives his power substance because he can usually use it, but occasionally it is thwarted.

Mmmmm the OP said he flies....

Flying bear trap thrown by flying fiendish half tarrasque awakened dire bear with scent and anti magic on...?

Sorry
