You might want to save one in your inventory. For example, you have a Thunder Taran Boa and suddenly get an Orkan out of event chest, and you put it on your other Boa. You love the Thunder Orkan Boa so much but you don't want to give up the Thunder Taran Boa since it is also so good(I don't know your preferences I'm just giving an example here). Here you can use both;

In another scenario, you don't use the Boa for long. Sometime in the future you desperately want to upgrade a weapon/robot but don't have enough silver. You can sell your Boa now.

Either scenario could happen, so it's best to save your Boa and not sell it yet. You can sell it anytime, anyway.
