Thats great :) The item is still quite unstable, but I guess it's preference.

Also, if I were you I'd get some spell pen. With your current build MR would utterly devastate your damage outcome.

evellyn is hard to play in the start. it is usefull in the start to take tp(shaman spell) to gank in the start in a lane kill a person and go back to your lane and your team is +1 kill in the start. try to make sheen is the start its helps with mana op and dmg with special ability after make boots 5 helps for fast ganks and go back to your lane fast. afters mejais with kills or assist grants you with good ap after make rylais is must item you have slow hp ap , if some team has invi hero must item is oracle!! after if the other team has too much cc(stuns e.t.c) do the cross it helps a bit, after complete the bane and last the ring to be more survival... thas it i hope you like it guys.

p.s exaust is very usefull when you nuke a target with low hp and this target has another hore beside him exaust the other target and kill the target with low hp easy...

i changed a bit considering the right thing you said ibelive this is much better

Mejai's last? Not worth it. Take it at the very beginning, or close to, or just forget the entire item.

You get 2 stacks per kill, which would result in a 10 kill streak without any deaths to get it maxed. That's not gonna happen.. (Not taking into calculation; The assists, would possibly help some, but as Eve is a ganker.. Meh.)
