Chen

Chen the Holy Knight's standard gameplay is different than most other Heroes. Holy Persuasion lets him teleport threatened friendly units to his fountain, and also allows him to 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. 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 across the battlefield.

Tips

 * 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 (select your creeps and press Ctrl+1, so everytime you press 1 you select your creeps) 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.
 * For jungling, it's useful to have a 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 Khan / Ursa Warrior (for the stomp stun/slow) and a 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 Hellcallers (with their nuke they take down creep waves easily), an Enraged Wildkin (its Tornado takes down creeps fast) or even 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.

Trivia

 * Chen's fun names in DotA Allstars were Chechen and Jackie Chen.
