Best ways to kill a Tier 1 caster without being one

[jseah]

@hall of pillars:
The wizard could easily demolish or bypass your hall (one maw of chaos and you can kiss your pillars goodbye, dispel/disjunction kills your anti-teleport). It's too easy to see it coming, and if the wizard is at all paranoid, he won't show up in that hall.
High level magic ignores location-based obstacles easily.


The way I see it, the wizard is playing a very unfair game (with respect to power levels, not to the challenge).
He has spells that help him strategically, retreat spells, I-ignore-your-attack spells, I-know-what/where/when/who spells, teleports and a secure base of operations (extradimensional/planar areas)
To beat that spent on defense, you need to be better at it than he is. And that means out-wizarding him.

In an actual campaign, any wizard on full defense could be impossible to kill but also operates at a fraction of his capacity than if he didn't have a perfect defense.
