I just reached MM.

Hello. I am currently a 120 Marksman who has just advanced, and I have a skill-build question. I am planning to eventually max Pierce first, but I do not know what is a decent level of skills that will preceed it. What level of SE and MMB should I have, and what order would be the best to get them at. I currently have 2 SE and one Frostprey, and have easy access to the SE20 and MMB20 books, aswell as DB20, but that wouldn't matter as much.

Thank you very much!
