Gray Demon Guide

Last Updated February 22 2023

Unlocked after completing Chapter 6 of the main story, a Gray Demon can be summoned by filling up the Death Match meter in Boss Battles. It is the main source of Gray Demon’s Wing, a material used to Limit Break heroes to Level 70 and above.

Gray Demons can fly and are invulnerable against melee attacks on the duration of the flight buff. Unlike the Red Demon, it cleanses all debuffs at the start of its turn which renders all crowd-control effects such as Freeze and Petrify to be useless.

## Gray Demon: Basic Info

* Attribute:  Speed
	+ Weak to  HP-type and strong against  Strength-type heroes
* Weak to  Fairies and strong against  Giants
* King’s “Bad Blood” with the Gray Demon decreases the boss’ damage by 30%.
* Immune to Debuff and Dissolve. Crowd-control and Ultimate Move Gauge depletion don’t affect the Gray Demon.
* Melee attacks are ineffective while the Flight Buff is active (only ranged attacks work). Melee attacks are effective when the enemy is stunned from falling.

### Flight Buff Pattern

 **Extreme** | * Phase 1: Starts the battle in a flying state and lands on the ground alternatively after 3 turns.
 **Hell** | * Phase 1: Starts the battle in a flying state and lands on the ground alternatively after 3 turns.
* Phase 2: Starts the battle in a flying state with a green flight gauge. When depleted, causes the Gray Demon to fall on the ground and get stunned for 1 turn.

## Strategy and Team Composition

The Gray Demon is a relatively simple boss to defeat. However, it does have a specific gimmick to deal with that can cause some issues for newer players who lack certain units.

This boss has a “flight” ability that allows it to dodge all melee-based skills (excluding Ultimate Moves). The only time it can be attacked with normal melee attacks is when it is dazed after falling, which can be achieved by attacking it enough to where its flight gauge is depleted. Still, in general you will want to kill it quick enough that dazing it will not be necessary.

Unfortunately, there are only a few specific units that can effectively speed through the boss, the two most prevalent being Green Festival Merlin and Green King. Merlin herself is the ideal damage dealing unit for the team, but can be hard for newer players to acquire given her status as a festival unit. Therefore, Green King is a relatively easy hero to get in comparison and he can fill for her role if necessary, though he is not as effective given he is a much older unit.

Regardless, the general team build for the team will usually have either Green Festival Merlin or Green King filling the DPS role, with two support units either providing rank-ups or an Attack-based Buff of some kind. For rank-ups, you will have to have Green Liz and Green Halloween Gowther together to eliminate RNG, as Liz will rank up the entire team’s hand so long as her Unique Ability’s conditions are fulfilled. In addition, Gowther will then be able to rank up the entire team’s hand again (including your allied player’s team), allowing you to start the boss battle with a full hand of rank 3 skills for yourself. Following this, you or your teammate would then use support Buffs (depending on who is running the Buffers vs the rank-up units). Finally, the DPS units can clear both phases quickly due to their increased Attack stats. This is by far the most reliable and consistent method to clearing the boss quickly.

If you lack Green Liz or Green Festival Gowther, you can try to find an AI teammate who does use them, meaning you will only need to have the support units. In the case that you can't find what you need in an ally team, you will have to go through the stage slower.

#### Team 1

Green Escanor and Red Gowther are only recommended for easier difficulties or if you are lacking better units for Green Escanor’s case.

Green Derieri and Green Zaneri can be used in the sub slot for increased rewards on Hell difficulty with the appropriate costumes.

## Rewards

Various rewards are given after clearing the Death Match which is necessary for Hero Limit Break, Hero Awakening, and Equipment Awakening.

### Reward Rules

* Increased chance to acquire better rewards for winning while alive.
* Increases Village Friendship upon clearing a Death Match.
* Gives buff to apply discounts to all items purchased with gold in the village shop.
