Contingency

[Cephid Arcanis]

Since contingency is seemingly omnipotent, use this.

"When I want it to happen, <fill in the blank>."

Excellently put. That is why it has to be only reactive and percieved by the wizard.

Which means we just brought wizards down a notch! Just sneak up a sneak attack him. No contincincy could possibly save him. Seriously!
In almost every thread about someone trying to kill a wizard the defence is "but my contingent teleport saves me". Like here: http://community.wizards.com/go/thread/view/75882/19873050/Caster_20_vs_Gish_20
Not any more! 
Quick guys, someone make a caster killer!

Foresight explicitly lets you see into the future.  So in an arena match, the contingency against X happening still works.

Good call.
Contingincy is level 6. Foresight is level 9. So until level 17 a wizard us still vunerable to sneaky dudes.
And beyond that, those wizards better have those foresights up thou. It only lasts 3 hrs at level 20, so either they cast it 8 times a day or they are open to sneakers most of the time.

What is that feat that lets you hide from blindsight etc?
This could actually be really easy.

Darkstalker lets you hide from the most common senses (Tremorsense, Blindsense, Blindsight, and Scent) and lets you flank foes with all-around vision, but that's it.

[Operation Shoestring]

Wow, almost nothing protects you from dispel magic or it's bigger cousins.  Wings of cover only blocks attacks (including spell attacks).  Can Wall of Stone even be made a contingency?  That could protect you if you activate it with a nonsense syllable whenever you detect anyone nearby casting dispel magic....

EDIT: Otiluke's Suppressing Field can stop Dispell Magic.  Alas, anyone who boosts his dispell check will probably beat you.

Yep, that's the one.
Whisper Gnome + uber charge build,
max stealth through the roof + Darkstalker.
Shadow dancer 1. Blind fold of true darkness.

1) Charge wizard (below 17th level)
2) Stab him in the head.
win

Just go ahead and sacrifice one level for a level of Cloistered Cleric and get some of the DMM, Persistent spell fun for your Foresight if you think it is a problem.

Only works on divine spells.

[Tshern]

It lasts 10 minutes per level anyway. Heck, you can even use Shapechange at that level. With CL 17, UMD'd Beads of karma and an ioun stone it lasts 220 minutes, use a rod to extend it and then the magical location that allows you to triple the duration of any transmutation spell once a day. So that's 22 hours already and there are forms that help you against surprises...

[Anklebite]

ah, the poorly worded dire tortoise. how I loathe thee.

[Tshern]

Or creatures that are just plain immune. Zodars for example.

Eh, I'd just use Illumine for this.  Saves on a feat and a turn attempt.

[Tshern]

And only works twice a day.

[snakeman830]

And only works twice a day.

How many times per day do you need to Persist Foresight?

[PhaedrusXY]

If you're going to burn two feats to be able to Persist at all, you should try to make the best out of them. If Nightsticks are allowed, you should be able to Persist more than two spells per day using them via DMM.

Of course as an arcane caster, you're a hell of a lot better off just dipping into Incantatrix for 3 levels than burning 4 feats and a non-casting level to get DMM...

While most time-affect spells are indeed trans, foresight is actually divination.

He was referring to Shapechange on that.

ah, Legendary Tortoise.

[Sooner]

This is kinda related to another thread but can polymorph be a contingent spell?
If so

Contingent Polymorph on self after saying "wonder twins powers activate" into the next thing you say.

I could see my DM throwin a book at me if I did such a thing.

Also would Contingency when the Rogue deals sneak attack damage cast invisbility on him work?
