The starting build is obligatory, you must start with these items and save money for a stout shield.If you are getting harrased just "BE PATIENT", you will rekt them.
When you get the level advantage and get a few decays it's time to kill, drop the tombstone,use decay and let them hit you, if they hit the tombstone just heal it with Soul Rip. if you are getting low hp just back a little bit, you have a mango and a salve if it's needed, the key is to mantain your distance from the enemy melee heroes.
