Demonic Beast Belgius

## Intro

There is one super important thing to keep in mind during this boss, it is unkillable while its allies are still alive. Therefore, it is important to kill the swords before attempting to damage the main boss. It is recommended to kill the left sword first as it is more annoying to deal with with its effects.

Another thing is that each swords does more damage to and takes less damage from certain races. Moreover, the main boss deals heavily increased damage to a particular race. The sword on the left counters Goddess race units, the sword on the right counters Demon race units, and the main boss deals increased damage to Human race units. Because of this, you want to avoid using these three races. Ideally, you will use Fairy race or Unknown race characters as they are not affected.

Thirdly, the main boss will freeze any unit that uses a Buff skill and that unit will take many times more damage than normal when they are attacked until they are unfrozen. To make matters worse, Belgius (main boss) will also deal increased damage to Buffed allies. As such, you can’t just sacrifice one unit to support as you are effectively getting the entire team killed.

## Building Your Team

As mentioned before, you’ll want a team made up of Fairies and Unknown characters. This is actually a good thing so it is much more free-to-play friendly than other Guild bosses may be for you.

Regardless, you’ll want the team to be majority Fairy race as they tend to work well together in terms of Unique Abilities. Units such as Blue Fairy King Harlequin, Red Helbram, and Green Elaine all make a good pairing. The Fairy race is a very small group of characters and the options are quite limited as it is, so these three would be ideal picks as the rest of them are either not good for this specific event, use Buffs, or are just plainly too outdated. The Holy Relics for Helbram and Harlequin are not required, but will of course make the battles much easier.

For the fourth and final unit on the team, a good pick is Green Festival Gowther. His Unique Ability buffs allies but not through a skill, so he will not be frozen. Not to mention, his own damage can be quite good when he has more Ultimate Move Gauge orbs. Again, his Holy Relic is not required but can make things easier. Alternatively, you can use Green Festival Merlin to serve as a secondary DPS option, but do not use her Ultimate as it will give the team a Buff and it does not protect you from the Over-rupture (10x damage to Buffed enemies) effect Belgius has. Merlin and Gowther serve two different kinds of roles, so they are not specifically substitutes for one another, but more like alternate ways to build the team.

Remember, associations do matter when building a team. As such, remember the power of the Graces the Archangel characters have and use them if you have them at a respectable Ultimate Move level (around 3/6 or above). Sometimes, it may be worth using them even if their Ultimate Move level is low, so use them at your own discretion. If you do use them, give Red Sariel's Grace to Blue Fairy King Harlequin as he will be a strong DPS unit during the fight. None of the other units on the team need any Graces in particular, but feel free to give them some if you wish. Red Tarmiel can be a good link for whoever you feel is taking most of the damage or isn't a DPS unit on the team (such as Green Elaine). Light Mael of Sunshine's Grace can work for your second-most damaging unit on the team (like Red Helbram as he won't Crit often so a base damage boost is fruitful).

If you are only planning to take on an easier difficulty such as Normal or Hard, you can still get away with using Demons, Goddesses, or Humans. At that point, you can pretty much build the team however you want, barring the exceptions like units with Buff skills, of course. The boss is weak enough to where you can just brute force it, but it will still take longer than the team using Fairies and Unknowns.

This team can work for all difficulty levels.

## Gearing up your Units

With this team, the gear to use is pretty straightforward. Blue Fairy King Harlequin will prefer Attack/Crit Damage gear, Red Helbram will prefer Attack/Defense, Green Elaine can work with either HP/Defense or Attack/Defense, and Green Festival Gowther can work with HP/Defense or Attack/Crit Damage. You will want Attack, Defense, and HP sub stats on everyone's gear. UR gear is naturally the best gear to use, but you can certainly get by with just SSR gear.

This team can beat all levels without food, but using it can help you if you are struggling.

## Strategy

At all difficulties, the strategy for beating Belgius does not change. You want to start with one of Fairy King Harlequin’s AOE attacks, followed by two attacks from Helbram on whichever sword you want to kill first, and then an attack from Elaine to put in a bit more damage. Using her AOE attack is recommended, as her single-target attack can actually help you against Belgius itself by lowering the rank of its skills. Gowther can help with his own single-target attack along the way if need be. You can also use his Debuff skill on the right sword to block it from using its Buff skill if it gets to that point.

You want to basically repeat this for the entire fight. Always attack with Harlequin first to grant you a shield to protect your team along with increased damage, and attack with other units until they are dead.

Note that Belgius has a Stance it will use that will allow it to take decreased damage. This is where you would use an Ultimate from either Green Elaine or Red Helbram as both of their Ultimates remove Stances. This is why you need to attack with them: not only for damage purposes, but to build their Ultimates. The boss should only get to use the Stance skill once, so you will only need one of the aforementioned Ultimates. Belgius is not very tanky, so it should go down quickly.

## Main factors of getting high points

1. **Number of turns passed** - Additional points are granted if the battle is finished within eight turns.
2. **Remaining HP** - Additional points are granted if all allies have more than 40% HP when clearing the stage.
3. **Attack with a hero that has attribute advantage** - Additional points are granted by attacking with an attribute advantage hero ten times.
4. **Last hit with a certain race** - Additional points are granted if the last attack is with a Fairy race ally.

There are also additional missions that can be accomplished to get more points, which change each week.
