If you get feed very early and you have enough money to buy the stuff for Rylais , do that instead of the second Doran's Ring. But then you should be careful with you mana.
When you have problems with Mana in this method try to buy first RoA and then Rylai's.
But if you care it won't be a Problem.

When you see you do enough damage change the zhonyas into a Guardian Angle (GA)

Framing for elise is very important especially in the mid lane, in early game it is easy to farm in human form with your W, because of the AoE Damage.

Later you should go in Spider From and Fram with auto attacks , the little spiderlings should clear all very fast.

The important combo of her in 1vs1 in the mid lane is going like that :

(Humanform)
First you have to hit you E (Stun),
After that avery fast (2.) Q and then a very fast (3.) W with the target of the champ (Sometimes the distance is to big and it won't hit , but in the most cases it should work)
Then swith fast in your Spiderform,
activate the (4.) E and land on the champ , then you speed (5.) and last the Q (6.) to get the maximum of the damage.

When you start diving you should be be lvl 3 or better,
Do this only when low or super low,
First jump on with the (1.) E,
(2.) the W and finish it with the Q (3.)

It should work but be careful with the tower you have to do it very fast on level 3 to 5.
At level 6 it won't be a problem.

Vicious and elegant, Elise's charismatic grace lures the innocent and greedy alike into her web of deceit. While her victims may discover her true intentions, no one has ever lived to reveal what dark secrets lie behind her enigmatic guise.

In dark halls, hidden from society, Elise preached the word of a mythical spider god. Her desperate followers hungered for the god's favor, believing its blessings to be the source of Elise's vibrance and power. When Elise proclaimed that she would lead a pilgrimage to the spider god's shrine, she selected only her most devout disciples to join her. Ecstatic, the chosen few followed her blindly as she led them on a perilous journey across the sea. When they came ashore at their final destination, the mysterious Shadow Isles, Elise led them to a cavern shrouded in webs. Expecting a shrine, the group looked to their priestess in confusion. She turned to the crowd and raised her arms in triumph, revealing strange, spiderlike legs that grew out of her back. Seeing her terrifying true form for the first time, Elise's followers turned to flee, but she conjured magical webs to trap them. With her victims ensnared, she turned to face the cave and uttered a screeching cry. An enormous undead spider-beast emerged from the darkness, dragging its hideous bulk on thick, pointed legs. Elise's followers could only scream as the monstrous spider ate them alive. She approached the sated creature, extracted its venom, and drank the strange substance. An immediate sense of rejuvenation flowed through her veins. With mortality delayed once again, Elise left to rejoin her congregation. They were overjoyed to hear that their fellows had chosen to remain at the spider god's sacred home. Elise reassured her disciples that she would lead another pilgrimage in due time. The spider god would be waiting.

"The truly faithful need not fear the spider's embrace." – Elise

Pls Beware of your E , when you hit to escape and no enemy is in Front of you to get rid of the one who is behind you , you will get to the same place as activated.
