Easy game – Easy lane.
Start: 5 pots cloth-armor and Greater Totem.
Dont trade so much before lvl 3 and stay on distance for Darius, let him push you to the tower more or less and farm like a god.
When you are lvl 3, start wareing him down when you got atleast 1 rage attack ready, E in, Stun him with W, Leech of him with Q and E out again before hes able to even touch you.
I usaly get firstblood here with alittle help of ignite. Go shop and get your first item: Brutalizer.
After this its a easy ride, your ulti counters darius ulti in many situations, dont screw that up!
Get Sunfirecape, Tiamat and upgrade it to Ravenous Hydra and a spirit vissage.
