Guide is still being built, im just releasing it for some people that i want to discuss it with. Dont hate </3

Diana in general is bulky assasin. I would argue she has the highest survivability out of all assasins. And to be honest - well played Diana can dominate them, even the ones that are giving headache in lower ELO plays. She crushes akali, kata, fizz and other snowballing champs quite easily, mainly because of her natural tankyness.

Diana's passive: Every third attack deals bonus magic damage. Damage deals AOE damage and is useful for pushing. Also, you might harass with that third attack, if your opponent gets close. Nice passive :)

Diana's Q is harassment tool pre-6, on farming tool if your opponent is forcing you to do so. When hit, enemys will get debuffed, and this will allow you to use your ultimate on them without a cool down.

Diana's W is a pretty interesting shield. When activated it gives her some shield and spawns 3 orbs around her. Each of them can hit enemy and deal damage. After (and if) all 3 of them detonate the shield is refreshed for a brief period. This is a very usefull skill in dealing combos and what makes Diana a nightmare to other assasins.

Diana's E is a utility skill, which knocks up target (canceling chanel abilitys. Dayum kata, no ulti for you :<). It also pulls enemys towards you, can can actually stop them from escaping even over the walls. You can pull opponents like shen, ez and graves over walls, back to their death!

Diana's R is ultimate ability, dahes towards opponent dealing magic damage. It is realtively low cooldown skill, however, if you hit enemy with Q and ulti them while they are still debufed, you ultimate will have no cooldown and you will be able to cast it again after a really short dealy (1sec).

Most of ranged mid's will try to force you out of the lane. Dont let them bully you, and try to stay in lane as long as possible. Against close-range mids, you might be the one bullying them, even pre-6! Your shield really gives you advantage to win most of the trades. Not too much to say here, try warding and play safe :)

This is your time to shine! Diana can deal massive ammout of damage with Q>W>R>AA>E>AA>R combo. Really, in most cases, you will get half of theyr HP bar without losing any of yours. Try forcing them out of the lane, be super aggresive. If you got a kill or forced them out - roam. Your Q and R is pretty lethal, and WE for slowing/pulling your opponents nearly guarantees a kill of other lanes, if you landed perfet QR :) Dominate the game!

Focus squishys, try taking them out. If you get focused - zhonyas! You wont die as quick as many other assasins, this might win your team precious time. Many people underestimate dianas burst, when in reality, her burst is medium, while chasing ability is super high. Keeping in mind her low cooldowns - shes a beast :)
