Mech of Fury and Sorrow

The Mech of Fury is the second Trial of the Chamber of Arms in Final Fantasy Brave Exvius. Players face the robot Elnath for the Zeus Mace. It is to be released in the Global version in 1/25th.

Known details

 * In HARD, Elnath has 4,000,000 HP split amongst 3 phases.
 * Elnath is Human and Machine, so Man-Eater and Machine Killer are effective.
 * Elnath is weak to Lightning (-50%).
 * In the 1st Phase, Elnath starts a countdown. If it reaches 0 it unleashes a powerful attack. The counter can be reset using Lightning attacks on him, but it unleashes a retaliatory attack of increasing strength the closest he is to reaching his Phase 2 threshold.
 * In the 2nd Phase, Elnath becomes immune to all forms of damage, and spawns two arm bosses each with 1,700,000 HP. These arms are immune to physical damage or magic damage depending on the arm in question. The player needs to kill both arms to able to damage Elnath, but there is a catch, as Elnath will remain immune to one form of damage for the remainder of the battle. This depends on the arm that is felled first.
 * Upon entering the 3rd Phase, Elnath will buff himself and unleash powerful physical and magic AoE attacks (this will likely result in a wipe of the active party in the transition turn). In the subsequent turns Elnath will no longer buff its ATK/MAG but will keep spamming his nuke attacks which buff his DEF and SPR.
