Ohh well, if you expect something close to the speed farming of a SR on a Swordman, let me tell you, there isnt, not for open world maps at least, CMs is perfectly fine tho, and yeah, Doppel can feel a little bit clunky next to a SR, but once you get the hang of the combos it’ll be much better
And well, if you do plan to grind in open world maps I guess you could take pelt, it would help out a little bit in that scenario, however, if what you want is to lvl up fast, just do the main story line quests, you wont have to grind at all till lvl 400ish, and from there on you can just spam CMs to make it faster
