KMST 1.2.411 - Phantom

Assuming all of these are possible, I would probably do:
1st: Haste, Dark Sight, Magic Guard, whatever
2nd: Heal, Hyper Body, Meso Guard, Threaten
3rd: Holy Symbol, Combo Attack, Combat Orders/Magic Crash
4th: Rapid Fire, Snipe

The versatility of this class is amazing. It can fulfill so many roles just with the skill stealing.

Putting both Meso and Magic guard on would probably be a bit redundant... And I think Meso Guard is a better option because Phantom don't have much MP to protect themselves in the first place.

I'd personally run
1st: Haste (Dark Sight is rather pointless with Card Shroud or w/e their ultra tele is called)
2nd: Hyper Body, Meso Guard, Flash Jump (Just because I can)
3rd: Holy Symbol, Combo Attack, Arrow Rain (While in 3rd job)/Combat Orders ((When in 4th)
4th: Everything.
