Hmmm I would have to say my Rakshasa Rogue (gestalt - race/class game). We entered a War-Torn city after a failed Teleport. This place was under full WAR. War mages were casting huge area effect and every block we went we had to take cover in a building to rest and recover.
We hit one block and the Were-Tiger Monk went down along with the Mindflayer Wizard and his Runeslaved Owlbear. I managed to make it 1 more block before my DR and SR gave out and I went splat. It was an EPIC powered game, fantasy warfare is brutal.
