Evelynn is great ap carry, who with a few kills can change the whole dynamic of a game. With incredible movement early on, chasing capabilities, and a close range nuke attack. A % health ultimate with a slow can turn the tide of a team-fight. This guide will help lead you into doing a good quick amount of damage while providing escape capabilities and a good way to snowball out of control.

Startmachete and 5 pots, for sustain and that little extra damage, buy Boots of Speed, then go into the spirit stone for extra damage and some sustain. After that grab a hextech revolver for extra lifesteal then combine the two to form spirit of spectral wraith . Finish your boots into Boots of Enhanced Move speed (works perfectly with the passive) After this item build a needlessly large rod or blasting wand (depending on team situation) and combine into Rabadon's Deathcap. When the deathcap is complete the rest of items are all depending on situation of team. Extra damage go with a Deathfire Grasp (active is great with eve), or if armor is needed go Zhonya's Hourglass, or if you want slow build a Rylai's Crystal Sceptor, and if you want extra penetration grab a Void Staff. Whichever of the situational items that you haven't bought yet, sell your Spirit of Spectral Wraith (by this time you aren't jungling) then build it into the last situational item, and you have your self massive amounts of DPS and CD reduction.
