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.
(pantheon) Throw spear always at the begin to make the opponent loose lot of health and when he misses some, you will be about LVL 2 or 3 you jump on him do heartseeker strike where you think hes gonna run and give one normal attack and throw a spear. (dont be scare to throw many spear at the begin because you can restore your mana with clarity and the ennemy can think that you are dead whitout mana, but you will have mana and you will kill him :)
