Dota 2/Chen the Holy Knight

Chen is a ranged intelligence hero who is usually played as a jungler, a ganker and a support. He can use Holy Persuasion to convert even the strongest creeps to his side. His Penitence will fill his enemies with guilt, slowing them down and making them more vulnerable. His Test of Faith will do random damage to an enemy, while being able to warp allies back to the fountain. His ultimate, Hand of God, is a powerful spell that heals every ally on the map.

Penitence
Penitence slows the targeted enemy as well as causing the enemy to take more damage. It is a good disable good for focusing and chasing down foes.

Test of Faith
Test of Faith does random damage to the targeted unit. The damage dealt is pure damage, which ignores armor and magic resistance. It truly is a test of faith, since you can either do a ton of damage or too little damage to matter, but its nevertheless a powerful damage nuke for most of the game.

Test of Faith Teleport
Test of Faith also has a sub-ability that teleports an ally back to the fountain after a short delay, having no delay if used on your converted creeps. It doesn't share cooldowns with Test of Faith itself, though since it costs 200 mana, you must learn to use it judiciously. A teleport used at the right time, however, could save an important allied hero.
