Arms and Continuous BM

[Goldmember]

Priority will depend on which faction you are and which heroes you are using. I would say most people work an Spirit hit arm first, and then either Valor hit or Element hit next.

For my full BM setup I got lucky on Valor hit early and then worked on Spirit hit. Now that Spirit hit is done I am working on Valor defense.

Not sure if my answer really helped you or not because everyone has their own priorities based on their type of build.

Good Luck!
