The dodge is for jungling, you could get armor runes, but the madreds obviously gives you armor and i feel that with the dodge yellows, you can easily jungle without and worry or need for armor, and ill actually explain the catalyst, shaco is very squishy early game, even with Hp per level runes or flat hp he will always be squishy, so, what I do is seperate the final part of madreds and get a catalyst so that after I have boots, madreds razor, and catalyst, im not so squishy that I can get nuked, I have necessary damage and armor, and I already have the boots, and getting the madreds and banshees afterwards are both quicker altogether

Short guide, easy to understand, abit unclear on the jungle route part, but still i got the picture =) the dodge runes ? since where is no added dodge chance in masteries or items( i have read patch notes and know phantom dancer dosnt give dodge anymore) why not try armor runes ? but dodge probly works well to, ill give it a shot. the fast catalyst, iam abit unserten about, shaco rly needs a strong early game to shine with madreads build. dosnt this gimp damage ? but ill give it a shot. looks cool.

thnx for commenting on my guide +1
