you are severly lacking in refining, wait for those general mobilization mission trading events they give out 50-70 medium refines you just need to complete traded missions i.e missions given to you by someone else. you c*so get alot of medium refines from the monthly event (not the calendar). group shop sells them too you can probably get 10 refines per week from the group shop but they have conan and chikushudo there as well so I don't think ignoring them is a good idea. see the problem with refines is that you have to let go of alot of stuff like ninjas frags seal scrolls and magatamas etc. refining gives the most power boost in the game and it will increase your ninjas damage as well the better refines you have the more often your ninjas will crit and do more damage plus you get more initiative which is the biggest advantage of refining.
