Trial of Angels

Trial of Angels is another PvE mode in which the player, similar to the Main Story and Underground (Story) has to complete stages and chapters in a sequential order. The player can obtain the rare Magic Crystals and Talent Potions here. 
=Structure of the Trial of Angels=
==Floors==
* There are no arcs in Trial of Angels. 
* Each floor consists of 4 stages. You need to beat all stages in sequential order to pass the floor.
* At the end of each floor, you will be rewarded with a generous amount of Diamonds, Gold, but most importantly, Magic Crystals. This is a one-time only reward similar to the chapter chests in the Main Story.
* There is no level requirement for advancing in Trial of Angels, but it should be noted that the stages are much more difficult when compared to both Underground (Story) and Main Story.
==Stages==
===Trials===
* Every stage consists of two fights: a Trial of Light, and a Trial of Darkness.
* The player must beat both trials of a stage in order to get the rewards and pass that stage for the first time.
* Units used in one trial cannot be used in the other trial. This means eventually the player will require two separate teams consisting of 16 units lead by 2 heroes.
* The player may change formation before each trial for that particular trial. For the second trial, they will not be able to reuse the same units and hero in the first one though.
* If the player has won the first trial and loses the second, they can repeat the second battle only. However, if the player exits the stage, they will have to beat both trials again.
* At the beginning of each stage, the player may choose a particular bonus. This bonus will be granted for both trials, and will also decide the order of the Trials. Choosing the Light buff will result in the Light battle happening first, and the Darkness buff the other way around.
===Resources===
* After a stage has been passed, the player may sweep that stage to obtain quick rewards without having to go through the trials manually again.
* Beating a stage for the first time grants the player a one-time higher reward.
* Sweeping or beating a stage subsequent times, results in the player gaining Unit XP, (specific talent predefined for each stage) and Gold. It is the potions that you will primarily farm here.
===Machines===
Later stages start introducing machines, that are either meant to hinder one of the players or grant them relevant bonuses. They also make some of the heroes highly valuable in certain stages (e.g.: Yog is a powerful counter to enemy Recovery Tent).
* Pit - placed on predefined spots on player's starting area, prevents placing units on specific locations.
* First Aid Tent - periodically restores an average amount of HP to all friendly units in its vicinity.
* Recovery Tent - restores a large amount of HP to a friendly units. (functions at very large range)
* Lightning Crystal Tower - deals a larger amount of damage to an enemy unit.
* Thunderstorm Crystal Tower - periodically deals damage to all enemy units in its vicinity.
* Monolith - teleports units passing through it to a pair monolith, usually placed on the opposite side of the battlefield
* Crystal Barrier - prevents non-flying units from passing until they destroy the barrier
* Summoning Cabin - periodically summons creatures for its controller to fight against the opponent.
* Devil Sealing Tower - periodically siphons mana from the opposing hero.
