good beginner guide... Start with this if you are low level caster.

It's a good guide for LeBlanc. I personally prefer getting distortion, but now that you mention etheral chains dealing damage upon hitting and upon stunning it seems more appealing to get it 2. But i am a terrible skillshot its why i dont play champs like ezreal Ezreal so i think i should stick with distortion :S

The guide on the other hand went through most of the important things. i think you should add another potion because you can buy 3 potions early on but thats not a big deal. also i agree with GETTING deathcap. but as the first item is a little useless because of the increased AP passive it gives. i think it would flow better to get 1 ability power item then your deathcap so that you get that extra Umph! to your spells early game
