I would still use Fargann rather than Louise. Hrossh spams water attacks. Louise's water reduction is only 50%, Fargann is 75%. The intimidation rate is no fun, but better than the greater pet food use.
I think I would replace one of those defensive Atma for an Offensive one. I don't know how close fargann was to death w/ all the regen/hp you have on it, I suspect there were not too many close calls keeping him alive. If you use something like RR you will kill faster and use less food.
I don't think Fargann takes 75% less damage because the second time I used the sheep pet and it took around 1000 damage from waterja and Fargann took around 500 damage. Also, using an offensive atma will definitely speed it up, just using regen atmas since it was the first time I fought it. You could fight alongside your pet if you just run away from waterja which supposedly is casted every 30 seconds.
I fought Iku-Turso w/ 3x bst. One switching between Sieghard and Shasra, myself on Fargann, 3rd on Louise. It was easily apparent when Waterja or Maelstrom would hit for ~1500 on Shasra, 750 on Louise and 350 on Fargan. (those exact numbers did come out once) This was consistent and easy to see. Fargann was resisting ~75% every time (and the mob spams those spells) while louise was resisting 50%.
Then again, I was using vicissitude which has a minor magic def bonus. However so was at least one other bst (shasra/seighard), if not both. Also not each cast is the same power. There is an element of randomness. Nazuna could have resisted partially, and the next cast could have been higher.
BTW, Kharon is a fun fight for bst/sch. I might use 1 pet food zeta on Yuly during the fight.
Atma: Vicissitude, Razed Ruin, Gnarled Horn. (/sch needed for dispel of dread spikes, /rdm might work if you can dispel it....)
For General BST NM soloing, I would usually recommend Razed Ruin, Vicissitude or Mounted Champion, and Stronghold or gnarled horn or Siren Shadow depending on pet and NM target.
First priority will be something w/ a major regen/def or vit on it. 2nd priority is Razed Ruin for your DD (RR is HUGE and will make a bigger difference than more def/regen if only 2 atma). 3rd will be more variable on situations, but you can probably get one that will benefit in at least 2 ways. Razed ruin crit hits are wonderful, the next thing for dd is atack+. STR just doesn't do much for normal attacks. You can quickly see a marked increase from attack+ however.
stronghold will give you more attack and def and REGEN, gnarled horn will give you agi (and consequently eva) and increased crit rate (counter-rate for merle also!) and Siren Shadow.
Everyone's atma availability will be a bit different as well. However Atma makes such a difference in abyssea, I think its well worth getting 3x lunar abyssite and abyssite of discernment, then atma, then armors and weapons. It makes doing it so much easier/quicker in this order, imo. Edited, Dec 22nd 2010 1:42am by Xilk Edited, Dec 22nd 2010 1:43am by Xilk
