Please note that Challenge Event Heroes are amongst the lowest odds of any Hero in the game. Like all other Event Summon Portals, the Portal Cost is per below: The “peak (maximum) of the Rage” is 75%.The damage is increasing with 15% each time when you use a Battle item or Special skill,and it is also decreasing with 15% if you do not use them in a turn.This is not mentioned in the description, but here are my notes about these: The Rage will be reduced if you don’t us any Special Skills or Battle Items during your turn.all status ailments of the enemies are cleansed at the beginning of their turn.Enemies deal increased damage based on the amount of the Rage they have: The more Rage they have, the more damage they deal!.In the Slayers of Fell Shadows event your actions can enrage the enemies! The Rage of the enemies grows every time you use a Special skill or a Battle Item,.
This feature is NEW and UNIQUE to the Slayers of Fell Shadows.
The use of Slayers Heroes in a given stage of the Slayers of Fell Shadows Challenge Event will give a bonus to those heroes.
This feature is NEW… or rather different same as in League of Villains and Starfall Circus
