Ao Kuang-The Midding Shenron

This build is a pretty basic Ao Kuang build. It focuses on his mana-MP passive while diving deep into MP, and if needed the added defense that comes in handy. Starting with the Warlocks Sash allows you to get stacks very early from farming mid making you somewhat fed early game. The stacks on it stay for the entire game and give you good MP and mana, for more MP. I usually get 1 level of boots because it's easy to get outran and die early game if you don't have any boots at all, but if this isn't a problem for you, don't buy them until you get the Warlocks level 3. The Gem Of Isolation is essential for the slow and MP it provides, making your Squall more dangerous and your tornado easier to get stuck in. The Rod of Tahuti is self explanatory, it just gives you a ton of MP. The Obsidian Shard has the same purpose, giving good MP and magic Pen. The Doom Orb is a great way to get a strong end and add the extra MP that will make you do unbelievable damage.

If you follow the second build, the Armor is meant to keep you safe from AD's, while also giving you MP from the mana it provides with your passive.

The Skill order is also pretty basic, getting the tornado mostly early for the farming, and the squall later when its damage is needed with the advanced slow thanks to the Gem of Iso. Your slither acts as a great escape but is not necessary past level one in most situations. Your ultimate, when hit, will destroy nearly everything in its path, so definitely get it as soon as possible.
