Sure you can. That's the advantage of having the option for dual builds on any character. One thing you need to keep in mind.. Since your first build is a crab even though the second will be Bane powers your character will still have the crab backpack in place. Once a cab .. always a crab

Ah ok thanks
hmm that backpack might get annoying after awhile sure there isn't a way to change things around between builds so i won't have it ?
the only way to get rid of the backpack permanently is to not have any crab spider builds
if you go to tailer and import a saved costume without the backpack, you can "temporarily" get rid of the backpack even with a crab build, but it will revert upon zoning
if you dont mind switching costumes before you zone, then that option will be fine for you to have both a crab and bane build
ok so if i switched to a bane build how would i attack without the backpack ?
would the attacks come from the mace or gun ?
if you have both a crab and a bane build, if you are using the bane build the backpack is nothing more than a costume piece and does nothing
the backpack is only used with crab spider attacks
ah ok thanks lol
I don't mind the backpack, so I had no issue with a Crab and Bane build on the same character.
i'm a 26 crab spider and was wondering if and how i can setup another build as a bane spider if this is possible so i'd have two builds one for crab and one for bane.
