Best ways to destroy armor

[darknighthg]

Hello...
Yesterday I was discussing with a friend about the rogue's weaknesses and ways to overcome them. We get to the point of what to do against a fighter with a heavy fortification adamantine armor (apart from waiting for him to take it out by himself). I looked at the PH and it states that you can't sunder a criature's armor. Then I thought about Shatter. The thing is, in a fair situation when both have 20th level equipment (let's say... both have for example, a cloak of resistance +6, a +5 tome, a +6 ability item, but not epic equipment or custom-made items), you don't have much chances to make the fighter fail the save.
So now I'm looking for ways to destroy/negate the fortification armor effect. Till now, all the ways I can think of are:
-Shatter
-Antimagic Field
-Dispell/Disjunction
-Energy missile/ray (in the case you play with the psionic/magic transparency)

I'm lookin, in order of interest, for: Combat tactic > Item > Feat > Spell > Prestige Class > 1-2 Class dip
Thanks for your attention

Penetrating strike could work against a heavy fort armor depending on how your dm reads it.....
Wands of dispel magic is the next best choice since you should be easily able to umd it and it is cheap enough....

In the case of "Penetrating Strike", one could argue that a 100% chance of negation, isn't exactly immunity to critical hits or sneak attacks.

A targeted dispel does seem to be a good way to suppress fortification... or if you could somehow have the opponent stuck inside an AMF w/o DEX bonus (give the rogue a "Ring of Improved Blinking" ) and shoot arrows at him from within 30ft.

Isn't that a homebrew feat?

Actually there are mundane ways of denying DEX bonus to AC. Marbles for example. But didn't thought about using blink to make an opponent FF. Thanks for that

It's an alternative class feature for a 3rd level rogue from "Dungeonscape", p.13.

That's why I said that it depends on your Dm and how he interprets it....
I would rule that it works against Heavy Fort but that's just me.....

Shatter only works on non-magical items.

So I introduce the WSA Greater Dispelling. It works three times a day. Then add Spellstoring and Shatter. Boom-chaka-lak-ka!

Also look at rusting, it's a touch attack.

Only the area version of Shatter mentions non-magical.  The single object target version does not.  Missed it in the 1st paragraph.

Right... me neither.

WSA?

What-where is that?

Yup... it's kinda tricky. Also we don't usually play with that book, but it's good to know it exists anyway. Thanks both

WSA=Weapon Special Ability (although that's not a commonly used acronym, I know that's what Captn means because he wrote the handbook ). Greater Dispelling was most recently reprinted in the Magic Item Compendium.

Something I don't understand about the rules of attacking objects is that it gives you all the calculations to damage armors (AC bonus because of it's enhancement bonus, HP, Hardness) but they specifically say that you can't attack them with the special attack made to attack objects (Sunder). It's very ilogic to me =/
