Weekly Raid Boss Thread

I have been making a lot of guides for weekly raid boss lately, so I decided to create a thread instead of posting multiple video guide posts. Here’s this week guide!

Weekly Raid Boss: Helgasercle Guide - The Burning Beauty

helg stats
This weekly raid boss is Helgasercle, Demon Lord whose mission is to take over the Mage Tower, and she used to be one of the strongest Demon Lords out there. She is a Devil-type and holy attribute with cloth armor. Holy attribute monsters/bosses are likely to take more damage from Dark skills/damages.

Helgasercle has 3,300 critical defense as default, and despite her type as a demon (0.7 CR Multiplier), but her XL size increased does factor in her critical resistance stats a bit. Based on my experiences, I don’t have any problems landing a critical attack against Helgasercle, so make sure to pick up Boruta card for additional boss damage.

Helgasercle has a lot of decrease defense debuff abilities, so expect some huge drop in your physical + magic defenses.

helga pattern

➤ Helgasercle’s first skill pattern is Flame Wall. She will summon a batch of a firewall that will move vertically or horizontally. The flame wall attacks are spawn in order from left, bottom, top, and right. There are several ways to deal with the pattern skill, which includes sitting the corner in the bottom left, or running through the gap between the firewall.

➤ Touching the Flame Wall ability will knockback, greatly reduce your character movement speed, and apply burn damage over time, so make sure to avoid the Flame Wall attacks as much as possible.

➤ Helgasercle’s second skill pattern is Sequoia Flame. She will summon a small fire minion, which grow over time, and eventually explode upon maximum growth. The minion explosion will apply damage and reduce block debuff.

➤Helgasercle’s third skill pattern is Meteor Shower. She will summon a giant meteor from the sky, dealing damage on impact, but also causing the ground to burn over time. The number of meteors will be multiple as you fight Helgasercle over time. Your best option is to stack the meteor in one specific location. Timing and practice are crucial to fight Helgasercle.

➤ Helgasercle’s fourth skill pattern is Rune of Magic. She will summons a red magic circle underneath her royal dress. Anyone who stands on top of the magic circle will increase their skill damage. The magic circle also applies for Helgasercle, so lure the boss away from the circle as much as possible.

Lastly, here’s the digital version + gameplay


This week’s boss is a nightmare. Many pattern combos will oneshot your character whatever that character is.

This is the most difficult pattern. Fire wall will inflict “slow”, which lasts long… and stacks. Longer than the interval between two walls, so it will stack fast and make your run over. Sitting in the corner doesn’t work, you will get two stacks immediately and if the boss is near she will rush you with her red aura and oneshot you. Trying to go through the gap is also RNG based, I’ve been hit by the debuff many times albeit being sure I crossed though the gap. Sometimes I just jump through the flames and nothing happens, so I guess it’s kinda bugged…

Is it me or Helga looks way hotter on this picture than in the game?


Everything about this boss is rigged in my opinion. You either sacrifice a few moves to deal damage and avoid the flame wall or completely bypass it with iframe skills (which only a few classes have it). The meteor is probably the worst part…

Also, Helga look pretty babe. I’m glad there is a NPC art version of her. I would like to see IMC adding Art version for other Demon Lord as well. :satisfaction:

Holy and cloth, this boss is like anti magic cleric dps, she make our damage so little /lemon

Thank you for the guide, it helped a new player like me

Watching your WBR video with a cup of coffee in the morning is my new habit, please continue your work for every week
