The runes in this build are geared toward getting you through the jungle with the least amount of trouble, amd getting you the items that you need to be able to gank effectively. Glyph of Magic Resist gives you MR allowing you to gank an AP lane, or bot with a AP heavy support, without taking to much damage.

These Masteries will make clearing the jungle very easy, giving you armor, damage reduction, health regen, attack speed, bonus damage, and lifesteal.

Starting Cloth Armor and 5x Health Potion gives you a far easier jungle than getting a Vampiric Scepter or boots.

Madred's Razors will allow even faster jungle clearing.

Berserker's Greaves increase the amount of procs you get from Madred's and allows for faster double strikes.

Wriggle's Lantern gives lifesteal allowing you to build health in the jungle when used with Meditate rather than going back to the base.

Building Pickaxe into Guinsoo's Rageblade gives your first AP boost and gives attack damage and speed that you need.

Sheen increases your AP and gives you a nice smack for your first activated Wuju Style and the attack right after Alpha Strike.

Bilgewater Cutlass gives more lifesteal and a slow to help you catch up to your target.

Hextech Gunblade gives a larger range on your slow and some spell vamp, which will cause your Alpha Strike to heal you.

Lich Bane gives more AP, some Magic Resist (Defenses!) and a stronger Sheen proc, it also gives a small amount of move speed.

Zeke's Herald will incease your very small health pool, and give you CDR for your skills, as well as attack speed and life steal.

Smite is required when jungling, it lets you clear so much faster. The bonus gold might seem small, but if you use smite at every opportunity it will build into a large bonus.

Cleanse will remove all CC from you, so when you get locked down by Lux you can cleanse and keep up the chase.

Counter Jungling can be done easily on wraiths and wolves, with an Alpha Strike. However golems may take a few extra hits and they're fairly far into enemy territory so they are not a good idea for counter jungling unless you know you'll have the time to kill the big golem. Always make sure to kill the biggest creep at the camp to get the most gold and take their small amount of health. this will also make them wait longer if they are waiting for the max gold buff.
