Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
ive been using this build/set up for playing mid or laning alone. Isnt really for anyone who dies a lot, and if you are dieing a lot your not using your pool at the right time or no one is calling out people missing. Boots could be switched out if facing a lot of magic users for the magic res/stun boots.
Transfusion is the 1st skill you want to max out since its your main harass spell and lets you stay in the lane longer.
Sanguine Pool is used for tower diving, running away, or slowing enemies for your team.
Tides of Blood is a great team fight spell but you dont need it early on but it is more important than maxing out pool first.
Hemoplague great Ultimate i use it for ganking early so i can get stack on the Soulstealer.
When ganking or jsut killing the person in mid start with Hemo, transfusion, tides of blood, then pool they should either be dead by now because hemo has went off or your transfusion will be back up if not your ignite.
Hope everyone finds this helpful!
