When you start fighting the world NMs you'll likely want MND for additional magic defense,
and will give more mp for seismic shock for dropping the Great buffalo
Prior to NMs ya, better off focusing on dex and str (not many magic using mobs)
Setup I use for NMs
Head: Silver tricorn or elemental crown
Body: Buccaneers shirt or Toad harness
Waist: Buccaneers or tarred sash
Legs: Kecks or Tarred
Feet: Buccaneer or Armored caligae
Hands: Reinforced mitt or Wrist spikes (reinforced is better but leather is more common craft for pug)
Neck: Mythril choker
Rings: Brass x4 or 2 elemental earrings (brass rings give best acc to slot cost ration)
Traits: Prime conditioning, Fleet of foot, Out of sight OR Intimidation (depending on if i'm tank or dps)
Stats (these vary as i'm always trying different combinations)
Str: 50-174 (damage might increase by one on flurry (per hit))
Vit: 140-174 (probably your best stat, for surviving)
Dex: 50-174 (if you want to evade an attack, use featherfoot)
Int: Base-50 (small change in seismic shock, but larger than str to attacks)
Mnd: Base-100 (doesn't help with peiste breath but can save you on gobby nm)
Pie: Base-100 (just doesn't help resist enough to be of any real use)
Elements: just leave them at 84, they don't seem to really do anything when
increased, but you will know when they are too low
Skills I don't use when tanking and whys
Taunt: doesn't generate enough enmity, mob goes back after casters and archers
(better to use accomplice, steal hate from the person with the most)
Light strike: Boost to def and eva is not worth the loss of enmity that flurry generates
Pummel: This base attack is just horrible, I don't even use this on normal mobs unless i'm farming.
(it's likely to improve if they change the way the tp system works)
Evasion first skills: the only exception is simian thrash, one it looks hella cool, second, it generates a ton of enmity
(I can tank with flurry featherfoot and simian thrash with no one pulling hate)
Discerning eye: meh, i'll take Raging strike, hawk's eye, ferocity (no stamina cost, more enmity, recover stamina)
(I should probably test this one a bit before i count it completely out)
Everything else is pretty much dependent on which nm
Everyone plays differently, all that really matters is that you have fun doing it ^^
These reflect my opinions, and are in no way the only, or set way of setting up or doing anything
