I'm not too sure about what killed the other champions in URF. Maybe it was ignite? Liandry's? Your spiderlings? I'm not too sure but those may have killed the enemy for you.
Also I have 3 builds, one for top, jungle and mid. For jungle I rush
,
and
. After that I don't immediately upgrade Haunting Guise into Liandry's since you need to become tanky for your team. I never go for Cinderhulk since you do no damage and you're not a tank, you're an AP bruiser. I get items depending on the other team, do I need armor or MR? SShould I get Zhonya or Abyssal? If I'm fed my build usually looks like this:
. I upgrade Haunting disguise only after I completed my full build.
As for the top lane build, I start with
and 3 health pots. Why not start with Doran's Ring? Because you use more mana then you think you do. I rush Haunting Guise and Sorcerer's Shoes again since magic penetration is a must on Elise. And then I get Rod Of Ages since I still need to be tanky but deal damage. Then I become more tanky after that. And I upgrade Haunting Guise into Liandry's after my build.
And now my favorite place for Elise, mid. I prefer her to be an assassin, not an AP bruiser. I start with boots, 3 health pots and 1 mana potion. Why not Doran's Ring? Because you need to be able to hit your opponent in spider form and catch up to them. I try to get Hauting Guise on my first back because then I can deal real damage onto my enemy. Don't be aggresive before you get Haunting because they will shrug it off like it's nothing. But then they'll be comfortable when you get Haunting and you can go all in and most likely get the kill before they realise it. Or they flash which means you can farm in peace and quiet while they back. If they stay then you can stun them, go into spider form and kill them. If they're under tower just Rappel after (or they survived) you finish killing them and the tower will then start attacking the minions. Most of the time my build looks like this:
. You deal serious damage and you can escape if you have an enemy to rappel to. Your all in spell rotation will most likely look like this. (Spider Form) E, R, E, Q, W, R, Q, W and then ignite.
These are my builds for Elise, feel free to ask me questions on these since I sort of main Elise :)
