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.
boots of speed first with 3 health pots, after go for catalyst and upgrade to rod of ages. upgrade boots now to sorcerers and then start on the second rod of ages. ALWAYS get catalyst first. U'll have alot of health with this build and the enemy will not expect u to be so *tanky*. Dmg output is still high and u will pretty much rape everything. if they get mr just get a void staff after ur 2nd or 3rd rod of ages. Works best if u get mid.
Flash is awesome just cause its flash, u can get ghost instead if u want, just need an escape mechanism
Clarity is a must since u dont have any points in utility for mana regen. The runes help but i find clarity to be amazing for early game hero kills.
