This build can be used for every kind of Medusa player. (Change starting items for ancient jungler; queeling and wards)

The skill build can be the way you need. I just made the skill build as I like, aggressive with snake and protective with shield. (you don't need split arrow in early game till you go jungle)

Farm and Farm all the game. No one can stop a Medusa lvl 25 with all its items.

Sorry for my bad English. I hope you to enjoy my build
