This was very hard for me to choose which runes because I know crtical damage is important to shaco but crtical damage was based on attack damage. So this is how I deal with it
there are total 3 rooms for Quint rune and 9 rooms for Make rune
so lets do some math here. When you do 9(amount of Mark rune) divided by 3(amount of Quint rune). It equals = 3.
So I compared 3 mark rune with 1 Quint rune.
Greater Mark of Attack Damage = 0.95 AD and Greater Quintessence of Attack Damage = 2.25 AD
when you do 0.95 x 3, it = 2.85 which is little bit more than 2.25 AD
But here is the critical damage runes
Greater Mark of Critical Damage= 2.23% crit. and Greater Quintessence of Critical Damage = 4.46% crit.
When you do 2.23 x 3 which equals 6.69%, the Quint rune which = 4.46 is soo much less..!
There is hugee diffrence in crtical rune..! mark rune is so much worth than quint.
So I had Greater Mark of Critical Damage and to fulfill my AD (for faster jg) I had AD Quint and movement speed.

I don't think it's really good on shaco but it's about an average.
so here is the diffrence between Maw of Malmortius and Mercurial Scimitar
gives you movement speed, and IT REMOVES DEBUFF..! So I prefer to use this if you are used to using active items, and if there are some champions such as ahri, lissandra, xereth
gives you 400 magic shield when you are attacked at 30% hp or under. So it's really good against some of ap champions who gives a burst damage. ex. LeBlanc, fizz, kat, akali
get Hexdrinker if you will make Malmortius because there are strong ap champions, and if you think you have hard time even with this item. buy Spectre's Cowl -> Banshee's Veil

Hi ! Thanks for the guide, i'm getting really good results from it ! :)
A question tough : wouldn't it be better to take a crit damage quint instead of the AD one ?

Is Hexdrinker a good item on Shaco?

haha Thanks for your reply Im trying to find better way in shaco and so. thanks for noting!
in justice of clown shaco

I was gonna make a shaco guide but this is a good guide so now im not in the mood to make one :P I really like how we have pretty similar playstyles (like honestly why max w next) I guess I should start playing more games with shaco and get myself to diamond :P

Try maxing W before Q it is stronger.

The CD on Sword of the Divine is halved whenever you get a champion kill (with all the stats it grants you, you are bound to get a kill) while the item is active. That means that your 60 second CD can go to being 30, 15, 7.5, 3.25, or even 1.125 seconds. I personally get Sword of the Divine on high damage AoE champions that can get multi-kills.

Thanks bro but yeah I think critical > ap or attack speed. Thanks for reading :D

Definitely some different runes, but I'm open to new ideas. Good guide overall, and I could see why you would want to max Deceive before Jack In The Box with this setup (since you took some crit dmg marks). I don't know about Sword of the Divine though, it's a wasted item slot when on cooldown. I could see why you built it though. +1 :)

Having armor itself is really useless to shaco actually. Shaco is one of most squishy jungler but strongest jungler. I prefer ad than armor. Esp. after armor nerf
