Nix and I completed Abbot on hard tonight:
It was meant as a speedrun with 2 people, i.e. fastest that can be done using just 2 people. So the puzzles were done in one round. We could have gone with either tiles => ice => asteroids or ice => tiles => asteroids, but in this run it was ice => tiles => asteroids, meaning that we'd complete both ice and tiles and enter into asteroids before the ddoors went down (within 90 seconds). You guys have probably seen us at Abbot's door quite a bit lately to practice; incidentally, a lot of time went into practicing roids due to invis/indestructible asteroids, especially when there's only 2 people throwing rocks. We also spent quite a bit of time just doing roids => main fight to practice those two parts of the raid.
The main strategy was using high saves and (improved) evasion to reduce incoming damage, and vampirism and good healing amp for when we did take damage. In this respect, it was similar to past runs of ToD/VoD for example that use high AC builds. In this case, however, Abbot's damage largely came from spells, and so it was high saves instead (to reduce incoming spell damage) rather than high AC (to reduce incoming physical damage). We would use cure serious pots on the run whenever the Abbot teleported around to improve our healing as well, although it wasn't strictly necessary (as we had vamp wraps), just that it sped things along. In a group fight, I think having good saves to reduce incoming damage is actually more important than your DPS, so making sure you got +dex, +con, and +5 resist items is likely more important than making sure you have triple pos.
I heard Nix is going to start giving out free completions if you have enough FRDS/TP so bug him, not me, about them. Really.
The most important thing to note is that Nix got the kill. What a kill-stealer.
