Clampearl doesn't evolve by leveling up. Clampearl can either evolve into Huntail or Gorebyss. To get Huntail, you have to choose to receive the Deepseatooth from Capt. Stern in exchange for the Scanner and then have Clampearl hold it while trading. To get Gorebyss, you have to choose to receive the Deepseascale from Capt. Stern and then have Clampearl hold it while trading. You have to choose one or the other. You cannot choose both.
By trading with held items. Have it hold a Deepseascale for it to evolve into Gorebyss, or a Deepseatooth for it to evolve into Huntail.
The Deepseascale evolves a Clampearl into a Gorebyss. If you have a Deepseatooth your Clampearl can evolve into a Huntail YOU NEED TO TRADE YOUR CLAMPEARL FOR IT EVOLVE.
If you give it to a Clampearl and then trade said Clampearl it will evolve into Huntail or if you give Clampearl a Deep sea scale and trade it it will evolve into a Gorebyss
Clampearl doesn't evolve on any level, you need to traded it holding deepseatooth or deepseascale. Deepseatooth makes Clampearl evolve to Huntail and deepseascale makes Clampearl evolve to Gorebyss.
Well it depends on what you want, (Gorebyss or Huntail) if you want Gorebyss you evolve it by letting it hold a deepseascale and trading it to someone at the same time, and for huntail you give Clampearl a deepseetooth and trade it with someone and when you get it back it's a Huntail.
There is no legitimate way to evolve it without trading.
Yes it does
It evolves into Huntail.
Clampearl does NOT evolve from leveling up. To get huntail you give it a deepsea tooth and trade it. To get gorebyss you trade it with a deepsea scale.
You cannot evolve Machoke into Machamp without trading Machoke, it must be traded in order to evolve it, there is no other way to evolve it.
You use it with a Clampearl to evolve it to Gorbyss
