level doesn't help you much... focus on getting some command flags, and getting 1050 at least or if possible 2100 cave keys from grocery for cave key rebate event (the gold essences are a must) and while doing that you will be able to go higher and higher in ninja exam thus able to upgrade your gear, try to get as many refines and charms as possible for rebate events (mostly everything you wanna do relies on rebate events to get extra for your item spending)
