Ionian boots! 15% cd! Lets just put it this way. Lux sits back & spams hero ulti! You need AP & CD! I believe ive gotn her ulti to 24(max stacks) second cd. And thats without CD runes. As far as Nashors tooth goes. Im actually surprised more ppl dont use this. 25% CD reduction + 55 AP! The attack speed aint bad either! Especially when after casting every spell you charge your enemy. If your good enough...Snare auto-attack, lucent singularity auto-attack. Your putn out some major dmg. You need the attack speed. Sounds crazy dont it? :D Well it is! And it wrecks! Try it b4 u bash it plz :] And obviously everyone has their own opinion haha :D Oh & btw dont forget to purchase brilliance elixirs! More AP + CD!
