Easy way to farm exp

[bearticz_]

For EXP- There is no easier way to earn EXP than killing multiple Yojimbos. As far as I know they can offer 8k-12k EXP if you do the "Beat the Elite Troops" or something mission... 

Another important note here is to mostly use your attribute points to defense, stamina, and Zankoku gauge as your strength can be enhanced using flasks, your defense and stamina won't. Don't worry about strength as you will inevitably need flasks especially if you are aiming for platinum.
