Hello everyone this is my first guide and I apologize ahead of time if it is hard to understand. I will have to start off saying that Elise is one of my favorite champions that Riot has released so far. Sadly even after the buff she still needs a buff to her health or something to really carry her on into late game. Her laning faze is definitely a lot better now after the buffs though. Especially on her E. I would recommend if you plan on playing her alot to buy her skin. Last hitting with her normal skin can be a pain because of the almost invisible auto attack. It is much easier to see all your skills in general including her auto attack with the skin. Personally I have found her to be great against any tanky melee or high hp targets.

This is a work in progress with be updating all the sections over the weekend.

Pros
Great combos
Great harasses
Can zone people with her Human form W
Great escape or gap closer if you are paying attention to you surroundings.
Can revile a team in bushes or things your normally wouldn't be able to see without wards.
Hard stun.
Some sustain
HP based dmg.
Super attack speed steriod
Can be built in many different ways

Cons
Slow even in spider form
Some abilities will still damage you even if you're in the air such as nunus ulti
Stun can be hard to land and it hits minions
High skill cap
Low hp
Falls off late game
Using your E in spider form can sometimes hurt you more then it helps you.
