Is a Lonely or Adamant nature preferred for the counter-sash set on Cacturne? the analysis says adamant but wouldn't lonely help endure max damage from counter? help please xD
It depends, versus 125 (Adamant) and 112 (Lonely).
If you want to maximize the damage of Counter I would suggest Lonely.
If you want to take a few physical hits which it can surprisingly do, pick Adamant. As it has a few good resistances Ghost, Dark, Water, Grass, Electric, and Ground and besides taking 2 hits, it can take a few more as well, which is great for Swords Dance.
