i think you have to trade for it
You can't catch shiny legendary Pokemon without cheats... sorry
You don't, it is used to catch spiritomb after meeting 36 people underground
It takes luck to come across a shiny, but when you find one you catch it like you would catch a regular Pokemon.
The only pokémon with a catch rate of 100 are Kadabra and Spiritomb. The highest catch rate is 255, the lowest 3.
The Spiritomb in Diamond, Pearl, and Platinum is level 25.

easy, i caught spiritomb in 5 minutes
It should be on level 20 or 25.
yes you do
do what to do to catch spiritomb but instead of 32 talk to 50 people in the underground and go to the hallowed tower with the odd keystone in it and it will be a lvl 100 shaymin instead of a lvl 50 spiritomb.
Pokebay is one good site for trading Pokemon cards.
You can catch Spiritomb when you have gone Underground and talked to 30/50 people underground and then go to the Hallowed Tower and insert an Odd Keystone into it, then Spiritomb should appear. It will be at Level 50. I suggest starting with Quick Balls and then Dusk Balls. If you plan to get Spiritomb's HP down, I will say that Spiritomb has no weaknesses, so it should be easy to get it's HP down. Eventually, if the battle has lasted so long, use Timer Balls. Hope this helps!
Spiritomb is Ghost and Dark Type. Extra Information: To catch Spiritomb, you need to place an Odd Keystone in the Hallowed Tower in Route 209 and have 32 conversations with a friend underground (You will catch Spiritomb in 25 lv.) Hope I helped :)

No but you can get it from the dream world. By going to Spooky Manor
Arceus or Spiritomb. It depends on who your going to fight.
