The standard start order is wolves, blue, wraiths, wolves, red, wraiths, gank. If nobody accidentally steals a wolve or small minion from you, you will hit level 4, leveling skills as q,w,q,e.
and kill wolves. Have people focus on the large wolf and take care of the small ones to prevent stealing crucial early experience. After killing blue, you should be level 2, take
to help sustain you a little. It is a one point wonder because the minion heal cap makes it not as useful as heals from items. Taking wraiths and wolves will allow time for your smite to come off cooldown and get you ready for taking red. Level 3, take level 2
. It helps you clear camps faster, and you take less damage because of that. After red, head to wraiths and gain level 4. Place a point into
and look to lanes to gank. I usually gank mid due to proximity, and an early lead for the mid lane can allow them to roam and gank the other lanes, increasing any lead gained.
A more risky start is to covert ops steal a buff. If I know I am against a blue start jungler, I can start wolves, and smiteless blue with help from my team, and I immediately run to their red to steal at level two. You can enter their jungle near their wraiths, but be sure to go around the back of red buff camp. If they are doing red, you have smite to steal it and bully them out of the jungle. Generally they would not be there yet, and you can bring the camp with you to the edge of the bush on the back side, so the camp would appear to be empty if they were walking past. A lot of junglers, upon seeing their red buff stolen, would immediately invade your red, so be sure to secure yours as soon as smite is off cooldown. If successful, you have gained a hefty experience bonus over your opposing jungle. Also try to keep stealing their jungle camps synchronized with your own, so once you finish one, you can know to head over to theirs and continue to build on your advantage.
