A Fei summoned from Fei Beasts god power decays over time; its hit points reduce till they reach 0 and the Fei dies. This decay can be temporarily arrested or reversed with healing, such as by Sages or Qilins, but the Feis will ultimately die after the duration of the god power. The Fei spawned from the Relic Tail of Fei does not decay and does not leave a poisonous trail behind. For the purposes of bounty or refund effects, its internal cost is 60 food, 8 favor.
Venom Trail (Passive): Causes 0.5divine (0.25divine for Feis spawned by Relic) damage (2ร vs myth units) per second to nearby enemies (land military, economic units, wild huntables, and itself) in radius 4. Chance to infect enemy units in range of 4 for 10 seconds with a dice roll every second with 50% chance, dealing the same damage per second as the poison aura.
Fei from Fei Beasts spawns 4 poison trail objects per second while it is moving, each lingering for 4 seconds, and having a range of 2 to infect and deals poison aura damage. Same chance to infect as the poison aura.
Bite attacks carry another 10% chance to infect enemy unit, with other attributes the same as the Venom Trail infection. As noted in the infobox, bite attack also causes 0.5divine damage (0.25divine for Feis spawned by Relic) per second for 5 seconds.
Attacks[]
The Fei deals damage through various means. All mentioned apply for both Fei from Fei Beasts and Relic Tail of Fei unless specified:
Its bite attack deals flat hack damage to enemy units and buildings, always.
Its bite attack also deals lingering divine damage to enemy land military units, economic units, and huntables, always.
A poison aura surrounds the Fei, dealing divine damage to enemy units nearby, always.
Divine damage dealt to enemy units in range of the poison trail left behind only by Feis from Fei Beasts, always.
Infection can be transferred through three ways to enemy units to deal divine damage:
Bite attack (10% chance)
Being in range of poison aura (50% chance)
Being in range of poison trail left behind only by Feis from Fei Beasts (50% chance)
Once infected, target cannot be infected again until the current infection expires; it neither stacks the damage nor resets the timer.
Note:Heroes are immune to all of these effects except the flat hack damage.

Feis are a powerful tool against both the enemy economy and their armies. As the damage from the Fei's aura is passive, it is applied even if Ceasefire is in effect, making it even more dangerous, as the Fei cannot be killed by units or buildings during the Ceasefire.
