It works better in duo but it still works in solo also.start off by getting your ruby crystal and head top. Be a little aggressive and try and get a kill but don't get killed. If u got a kill u should have enough to get phage once u recall. If u don't just keep building frozen mallet and get a ward or two for top. After u get ur axe go back Into lane and just be a little bit more aggressive but dont forget to play smart , once u get some minion kills and 1 or 2 champion kills go back and get boots by than u should know weather or not u should get merc treads or ninja tabi or cdr boots . And probly by close to mid game u should have enough for frozen mallet if u are getting fed and killing enough minions.

By the time mid game comes u should have your boots and frozen mallet and you should be pretty tanky. Next item is the bloodthirster and after either mal or guardian angel I usually get both because if your here it's almost late game so why get Bonetooth necklace.

By the time late game comes u should be really Tanky and do quite a bit of damage next you pretty much add what u want next like Blackcleaver or last whisper but those arnt required if u still don't fill Tanky enough than get randuins omen or frozen heart. By now u should have been in allot of team fights and should be close to winning.
