I would just recube...any line of %att/boss would be better and since it's already legendary just use a few cubes and you should get much better stats

I'm in scania, and ive seen similar hearts for the 2b+ price range. Idk how different bera prices are, but it shouldnt be too different. In my opinion, you should cube to get rid of that annoying %int especially if you plan on selling it. If you are going to use it, and you dont want to risk losing the all stats (or just use black cube), then it may not make a difference to you. I've had similar potentials before, your first 2 lines are impressive, eg. 9% att, 9% all, then you look at your third line. Magic attack. GG Nexon.
