Boldore evolves into Gigalith only by trading. So you will have to find someone to trade back and forth with so that he will evolve.
actually, boldore evolves when you TRADE it.
Gigalith does not evolve. Boldore evolves to Gigalith when you trade it, rather than at a specific level.
Bodore evolves into Gigalith when you trade it.
He evolves into Boldore starting at level 25.
I presume you have misspelt Boldore in your question. Boldore does not evolve at a level but when traded for any pokemon. It evolves into Gigalith, the one who receives the Boldore in the trade keeps it unless it is traded back.
It evolves at level 25 then boldore evolves by trade
Roggenrola evolves at level 25 into Boldore on Pokemon Black.
Rogeenrola evolves into Boldore at level 25 :) Hope that helps--Taylor
Roggenrola evolves into Boldore at level 25. You can evolve Boldore into Gigalith by trading it.
boldore evolves to level 34
Boldore can evolve at any point since it evolves once you trade it and both it and its evolved form of Gigalith have the same level-up moves so evolving early or late does not matter in Boldore's case.
Boldore evolves when traded to another person, it will evolve when it arrives.
