As with all normal AD caster/caries, one must be attuned to the SPIRIT of the champion itself, so first, you must grab your closest unicorn horn replica and glue it to your forhead. This will attune you to the CRITRAKA frequency, and you will realize how much power she posseses.

For your Runes, you must first realize that you are a part of the peoples republic of China. You must become one with the chinese, because this way, the only things that can hurt you, are burst heavy champions and the government. Now.
For your Reds, take Greater Marks of Critical Chance,
for your yellows, take Greater Seals of Gold, along with Greater Glyphs of Cooldown Reduction and top off your runes with Greater Quintessence of Gold, for the optimal, gold gaining rush. With such runes, any pleb that defies Crit-Raka, will be demolished.

For your masteries, try going 30/0/0 as to maxamize your damage output potential. Crit-Raka has all the defensive sustain you will ever need, so dont bother putting points into the *****/Useless catagories.

Max Q, into E, and finish off with your W, so your annoying, toxic teammates dont complain. You are Crit-Raka. Not some ***** Sorraka.

Best build. I r8 8/8 m8, dont h8, don8.
