Seasoner is trying to route it and do the grinding route as well to level 72. If you want here is the discord https://discord.gg/jjvMJCU.

Yeah, my main plan is to get the legendary weapons unlocked asap and go from there. As far as grinding money, I would say the gambling missions aren't that useful since a mission called Er Rai in Extra Chapter 2 gives 5k Gold per success and it's 1 fight rather than requiring 5 wins for a reward not equal to 25k (at least I don't think any of them give that much)
