Here's a nice way to prep for an
antimagic field. Cast
wall of iron. Then
fabricate it into a dome (and/or cone) that easily encompasses your space (preferably Large sized). Then cast
shrink item to turn it into a tinfoil hat. Any time you get hit with an
antimagic field the 'hat' turns into a source of 100% cover, which will block any source of damage for at least 1 round, in which case you can easily
'port out. It can also be used offensively! Just
fly up, turn it upside down over the warblade, call the command word, and let go. Paranoia pays off.
Also, I'm sure there's a spell somewhere out there that summons and/or creates large amounts of acid. Use
shrink item to turn a pool of it into a patch of cloth. 20d6 acid damage ftw.
Also also, buy a few manifestations of
quintessence. Then cast
delayed blast fireball. Combine. Enjoy your delayed blast firebombs.
Also also also, to ensure your safety, find a way to get the outsider type (whether through being a neraph, the Otherworldly Greyhawk regional feat, or some other means), grab Assume Supernatural Ability, and
polymorph. You can now turn into a nightmare, which gains
astral projection as a supernatural ability, usable at will. Store your body somewhere safe, and the only things that can kill you for more than a single round are A.) something that traps your soul, B.) a githyanki silver sword, and C.) an astral dreadnought. I doubt he'll have access to any of them. (As an added bonus, as a supernatural ability it can't be dispelled.)
