Level 36.
you can't find a shelgon in pokemon sapphire. you have to have the hm surf and waterfall, then go into meteor falls and find a bagon. Level up bagon to lv.30 so it can evolve into shelgon. And you can evolve shelgon into salamence at lv.50
evolve bagon (found deep in meteor falls) at lvl 30 in to a shelgon.
If you want salamence, you have to evolve your bagon into shelgon first. Bagon evolves at level 30 and shelgon evolves at level 50 ( I think this is right).
Bagon evolves into a Shelgon at level 30.
Train a Bagon to level 36 to get a shelgon.
Evolve Bagon.
you can't find shelgon in saphire you have to catch a bagon at meteor Falls first then evolve it
Bagon evolves into Shelgon at level 30. Shelgon evolves into Salamence at level 50.
Bagon evolves in to Shelgon at level 30.
bagon evolves into shelgon at lv.30 and shelgon evolves into salemence at lv.50
Nowhere you must train a Bagon to level 30 to get Shelgon.
Evolve the Bagon into Shelgon. then you can evolve Shelgon into Salamence.
