Inferno Grimlok Yggdor Guide

Quest Information
Upon completing chapter 20 you will unlock a series of high level quests accessible through the Grimworld Portal. This guide is a walkthrough for the battle against the Forest Grimlok, Yggdor.

Boss Mechanics
There are certain mechanics that will occur at specific times in the quest. This section will outline the major boss mechanics in order of occurrence.

Summon Yggl
Yggdor will summon a mini-Yggdor named Yggl at time 0:30 and 2:30. You will be alerted when this occurs with a message on the screen stating "Yggl has appeared.". It is important to deal with Yggl quickly as it has strong attacks that will deal a lot of damage to your units. To kill Yggl, change combat mode to Focused and switch targets to Yggl.

Fatal Blast
Yggdor will charge up a special attack called Fatal Blast at 0:45 and 2:45. You can see the skill charge to the right of his HP bar. This attack is a global attack that does a fixed amount of damage to each unit depending on their element. The following table outlines the damage values for each element :

To survive this mechanic, try and form a team with the best elemental advantage and optimise your weapon/accessory grid to provide your units with sufficient HP. If your units survive, they will most likely be brought to a very low health and so it is recommended to use a healing Brave Skill after this mechanic occurs to ensure that your units don't die.

Unconscious Fighter
This mechanic will occur multiple times throughout the fight from 1:00 onward. The first time that you face this mechanic there will be a message on the screen that states "Remove the Scorn from unconscious fighters!". Subsequent occurrences will not alert you.

Yggdor will stun the unit that he is targeting. He will then channel a powerful attack which will kill the stunned unit if he does not change targets. To deal with this mechanic, generate Scorn on any of your other units to take Yggdor's attention away from the stunned target. You can do this in multiple ways such as using a battle skill with high Scorn generation or using a powerful Brave Skill.

This stun effect is a recurring mechanic that is indicated by a status effect icon on the targeted unit. As you will not be alerted of this mechanic after the first occurrence, you will need to keep an eye out for it and deal with it accordingly.

Circle Stun
Yggdor will place a timed effect on your main unit. This effect is an AoE stun that will stun the main unit as well as all units within the effect's range. The effect's range is indicated by the pulsing orange circle surrounding the main unit. To deal with this mechanic, run.

All targets who are stunned will take large amounts of damage from Yggdor's attacks. It is important that you try and avoid stunning any of your sub-units as there is a high risk that they will die from being stunned. Your main unit cannot avoid being stunned.

Break
At around 3:00, there will be an alert stating "Could get dangerous if you don't BREAK!". If you do not BREAK Yggdor by 3:30, Yggdor will inflict weakness and seal on all your units. To deal with this mechanic, BREAK Yggdor.

True Power
At around 3:40, there will be an alert stating "The scales fly off and its true power is unleashed.". After this point, Yggdor will start to inflict seal on your units. You can remove this status effect with the seal removal item.

Fatal End
If you do not defeat Yggdor by 5:30, he will charge a special attack called "Fatal End" that will kill your units and end the battle.
