Is 6* paramount war Luffy free? Hi guys, I'm new to the game and I've finished all the missions which give his shards, however he's not maxed yet...it stopped at some point where he's level 93 and I really want to have a decent 6 stars lv100 unit. Is there another way (maybe an event) to farm those last shards without special training or stones?? 

And since I'm here...which free units reach max level? I'm getting lots of red Shanks shards as loging rewards but again I don't know if that's all the way up to 6* or will be like this Luffy...by the way is this Shanks at lv100 better than farmable units from the shop (like Marco or Snakeman)at 5*?? Thanks
