Chen the Holy Knight has gameplay that is different than most other heroes. Holy Persuasion lets him convert creeps to his side, including powerful neutral creeps. As a result, Chen is usually found in the forest searching for creeps to convert. When he finds a strong creep or two, he descends on his unwary enemies, using both his own spells and the abilities of his persuaded creeps to take them out. When ambushing enemies, Chen generally uses his Penitence ability, which slows the target and causes them to take extra damage from Chen's flock. Test of Faith can be used to finish off enemies and also teleport any ally to the fountain after a short delay with a subability. Chen's support abilities are rounded out by Hand of God, a healing spell which instantly restores a set amount of HP to all allied Heroes and fully heals his controlled creeps across the battlefield.
 Recommended items
- You should try to end the game as soon as possible, because Chen's effectiveness diminishes as the game progresses.
- Chen is a good jungler and can take any camp at lvl1 if you skill Holy Persuasion.
- While jungling, don't be too selective about the creeps. Just persuade the higher lvl ones in the large creep camps and persuade others if they are on low HP.
- Try to keep your creeps group in a Hotkey of some sort (Command groups, tabbing, selecting all other units) and also have another hotkey for both creeps and Chen.
- Always try to send in your creeps while keeping Chen at a safe distance (dont send him in the middle of a battle with your creeps) and keep an eye on him and his hp while controlling the creeps.
- Always try to keep an eye on the minimap in case you have to use Hand of God to heal a teammate.
- Try always to have enough mana to use Hand of God when it isn't on cooldown, as it may be needed at any time.
- For jungling, it's useful to have a Satyr Tormentor(Satyr Hellcaller), as it makes your creeps regenerate HP faster and can use an AoE spell.
- For ganking, it's very useful to have at least a Centaur Conqueror(Centaur Khan) / Hellbear Smasher(Ursa Warrior) (for the stomp stun/slow) and a Dark Troll Summoner(Troll Warlord) (for the Ensnare so the centaur can get positioned)
- You can have guaranteed ganks at lvl 1 or 2 if you get either a Centaur Khan or an Ursa Warrior and your ally has some stun/slow
- For pushing, it's very useful to have either Satyr Tormentors(Satyr Hellcallers) (with their nuke they take down creep waves easily), an Wildwing Ripper(Enraged Wildkin) (its Tornado takes down creeps fast) or even Centaur Conquerors(Centaur Khans) (they are tanky)
- For team battles, Centaur Khans are the best option, as they can keep the enemies stunned for up to 6 seconds.
- In team battles, try to use your Mekansm (if you have it) before Hand of God as it gives an armor boost too.
- Try to use either Mekansm or Hand of God when all your allies are damaged to maximize the healing, rather than just healing a damaged ally while the rest are with full hp.
- Try to kill Roshan around level 6-7 since your creeps can tank it very well and you can instant heal them with your ultimate.
- If the game keeps going on until late game (which you should avoid and try to finish the game fast) you should persuade an Alpha Wolf, and make it follow your carry, as it will greatly increase his/her damage dealt.
- Be especially wary of Doom, Lifestealer, Enchantress and Clinkz as they can take away your creeps instantly and with the help of a Hand of Midas two of your creeps can be destroyed before they even get near the enemy. Clinkz is a special mention as due to the fact that the creeps Chen persuades have increased HP Clinkz not only gets a huge HP boost from consuming your creeps but also a large damage boost on top of it using his ultimate. The same can be said about Naix if he is not properly locked down as he can use the increased HP of your creeps to not only Infest your creeps to heal himself on the spot but also deal nuke damage back to you and all of your allies present. Doom and Enchantress on the other hand while incapable of healing themselves using your creep can instead use the abilities of your own creeps against you as Doom's Devour skill grants him the skills of the creep he consumes while Enchantress' enchant simply takes the creep from under your control.
- Also be wary if the enemy team has an Ancient Apparition as Ice Blast prevents your ultimate ability from healing the affected units, somewhat serving as a direct counter to your ultimate ability.
- Chen's fun names in DotA were Chechen and Jackie Chen, a pun on the name of the famed actor Jackie Chan.
- Chen is the only Intelligence hero who has 5 spells, along with Ogre Magi.
