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.
At the beginning:
50 magic resistance
grows your lifereg. to 23 all 5 sec + 0.3% at lvl 1.
That gives you the great advantage to spam your axe without losing any life (if you dont miss the target all the time). You also regain all your life very fast so theres no use to spam you with casts or attacks.
affects that your ulti heals more and reduces you cd a little bit.
Warmorg's Armor also makes your ulti more efficient because you have over 1000 bonus life (if warmog's armor is full).
Now if you have no problems with the enemy caster or carries you can buy 3 times Warmorg's armor so you have 4. If you do/can do that i promise you you wont die with your ulti.
But normally this doesnt work so buy for more magicresist and for armor and life.
In the end you can buy another to get the ultimate lifekick :) .
