Zhong Qui is an excellent mage who can put out an absolute ton of damage, but he is quite short range. His lane clear is great and he can gank pretty well so be sure to check him out.
(By the way, this is my first guide :3)
The Shoes of Focus are a great item to get for several reasons; not only does it give you movement speed which is crucial on a god with no escapes, but it also gives you cooldown reduction which is always good on mages. The reason we choose these instead of Shoes of the Magi is that you deal enough damage to not need the penetration that item offers.
Doom Orb is a great item for this build because of Zhong Qui's fantastic lane clear, meaning that you can get lots of stacks quickly! It's also great because it gives you some mana and MP5 which is great for Zhong Qui as he is very mana hungry, particularly in early to mid game.
This item really is crucial for Zhong Qui because of the fact that he has no proper escapes. The protections are really good but the best thing about this item is the CC reduction which gives you a much better chance to get out of a fight alive. The reason you would choose this item over let's say voidstone is that it gives you more protections and the CC reduction really is good, also you deal enough damage to not need the magical power from voidstone but if you are against alot of magical enemies then you can take voidstone instead.
The Gem of Isolation is a great item for Zhong Qui for multiple reasons. The first reason is that it gives you magical power, meaning that you deal more damage. The second reason is the health and mana which give you more sustain. The third reason is of course the 25% slow, which is superb on him because of the lack of jumps and chasing abilities on the god.
Polynomicon is really nice for Zhong Qui beacause it gives you damage, lifesteal and mana; these three thing are great but the item also gives you a buffed basic attack after you use an ability which can really help secure kills when an enemy is on low health.
The Rod of Tahuti is great on pretty much every mage. It give so much damage because it gives you 125 magical power and 25% extra from all of your items together meaning that with a finished build you will have 512.5 magical power.
Passive: Demon Bag
The demons that Zhong Kui captures from Exorcism are stored in his demon bag, giving him additional protections for each demon captured. When Recall Demons is activated, Zhong Kui gains double the protections from his Demon Bag, but eventually losing all stacks when the bag is empty.
This is a really fantastic passive, particularly early game, because it gives you SO MANY PROTECTIONS. I mean seriously, you get 3 magical AND physical protection for each stack and the limit is 20 stacks, giving you a whopping 60 protections; that's the same as a bulwark of hope that is physical as well!
1. Expose Evil
Zhong Kui pastes a card on all enemies in front of him, marking them as a demon, slowing and damaging them each second while they are marked. If the card is removed, 50% of the remaining damage is done instantly.
Damage Per Tick: 20/30/40/50/60 (+15% of your magical power).
Slow: 20%. Card Lifetime: 6s.
This ability is pretty damn good but is mostly used as a setup for his other abilities because it makes them more powerful.
Zhong Kui drives out the demons of his enemies, dealing damage as they leave the body. Demons marked by Expose Evil are captured by Zhong Kui, healing him per demon captured (up to 3), and have the card removed.
Damage: 75/125/175/225/275 (+50% of your magical power).
Heal: 30/45/60/75/90 (+20% of your magical power).
Zhong Qui's 2 is really what this guy is about, it really does do ALOT of damage and if you use it in conjunction with his 1, you can heal back most of your health.
3.When fired, the Book of Demons deals damage and stuns nearby enemies, with marked enemies getting stunned for 2x the duration and removing the card. When this ability is not on cooldown, the Book of Demons flies nearby Zhong Kui, firing for 50% of Zhong Kui's basic damage.
Damage: 60/115/170/225/280 (+70% of your magical power).
Stun: .5/.6/.8/.9s (2x for marked targets).
This ability is really the only way that you are going to get out of a sticky situation, the stun is good but it only has a short range.
4. Recall Demons
Key Bind: 4
When Zhong Kui activates this ability, demons pulse out from his bag at nearby players every second for 5s. They chase and accelerate over time, doing damage to enemies and healing to allies as they enter the body. Zhong Kui is immunte to crowd control for the duration.
Damage: 80/95/110/125/140 (+20% of your magical power).
Healing: 25/40/55/70/85 (+20% of your magical power).
Zhong Qui's ultimate is really quite strong, shooting unstoppable demons at everyone in the area of effect around him. This ability is really great for teamfights and can be used as a somewhat decent escape because of the CC immunity.
As this is a solo lane guide I shall be talking about solo lane playstyle.
