Chen build & guide (7.41)

Penitence

Damages enemy unit, forces it to move slower and lets allies attack it more quickly.

Holy Persuasion

Chen takes control of an enemy or neutral creep and receives a percentage of its bounty. Its maximum health is set to 400. Converted creeps will have increased movement speed and bonus damage. Chen may globally target his own creep if it has not taken damage in the last 3 seconds to unsummon it.

Aghanim's Shard: Allows Holy Persuasion to target Ancient creeps. Can control up to 1/2/3 Ancient creeps based on Hand of God's level. Additionally levels up some abilities of creeps by 1 level.

Divine Favor

Passively provides an aura that grants increased health regeneration. Can be cast on allies to provide them with bonus armor and increasing the healing and health regeneration they receive. If cast on Chen, all units controlled by Chen receive the buff.

Zealot

Whenever Chen respawns, he is joined by a Zealot, a melee warrior creep with the ability to sacrifice itself to heal or deal damage to an enemy. The Zealot receives Holy Persuasion's benefits and scales up with other lane melee creeps as game time increases and gains extra base damage. The Zealot respawns next to Chen. Zealot may be activated to teleport a unit under your control to Chen after a 6 second delay. If Chen is targeted, it will teleport all units you control. Taking damage from enemy heroes or their units will cancel the teleport.

Hand of God

Heals all allied heroes on the map as well as all units under Chen's control. A large heal is applied at first and a slow heal over time is applied for 10 seconds afterwards.

Aghanim's Scepter: Decreases the cooldown of Hand of God to 40s and it becomes a channelled spell that lasts for up to 6 seconds. The initial heal happens at the start of the channel, and while channeling other nearby allied units become debuff immune with 60% magic resistance and the power of the heal over time is increased by 200%.
