Belo'ren, Child of Al'ar Mythic Boss Guide

Welcome to our Mythic Belo'ren, Child of Al'ar Boss Guide, the first boss in the March on Quel'Danas Raid. Learn about the Mythic specific fight mechanics and the strategy we recommend to defeat this boss on Mythic difficulty!

This guide focuses on a Mythic strategy, and won’t explain the basics of the fight, so make sure you read through the Heroic version of the guide for this boss if you are unfamiliar with the encounter.

Fight Style: Single Target in Egg Phase and Cleave in Regular Phases

Recommended Setup: 2x Tanks / 4x Healers / 14x DPS

Recommended Utilities: Warlock Gateway

Hero/Lust Usage: During 1st Egg Phase

Addons: Northern Sky Raid Tools

Mechanics-wise, this is honestly one of the easier penultimate bosses we’ve had in a while. Do not get baited by that. You can still rack up 100 pulls on this boss fast if people don’t understand the plan, because the Mythic changes punish “random soaking” or a “whatever, someone will handle it” attitude.

The biggest Mythic differences you actually feel are:

• Infused Quills now splashes around the person hit, so you cannot have multiple people accidentally intervening the same Quill.
• Radiant Echoes are now a wipe condition if an orb touches Belo’ren, so “we’ll just let that one go” is no longer a thing.
• Missing a kick or having a Phoenix Egg respawn usually leads to wipes.

Cooldowns and Push Timing

First thing you need to plan is your DPS cooldown usage, because pushing at the wrong time ruins your egg phase.

On pull, you can use anything that is 2 minutes or less. One minute cooldowns can be used on cooldown, because you’re aiming to push the boss at around 1:50, right after Belo’ren finishes Voidlight Convergence.

That being said, it’s often better to hold a bit, because you may need to stop damage to hit the correct push timing. Pushing too fast is the easiest way to grief your egg burn, and the first egg phase is where you do the real damage. If egg one is good, egg two is basically a formality.

Having two Hunters makes this boss considerably easier, but you can replicate the idea with other mobile immunities.

Markers and Starting Position

Start by pulling the boss to Green and face it toward the pillar. Nobody should stand there, that area is reserved for tank frontals.

Each Phase 1 plays the same, with one element of RNG: the orientation of Radiant Echoes spawns. You can get Horizontal or Vertical, and you are guaranteed to see both during Phase 1, just in a different order each pull.

Radiant Echoes Handling

Horizontal

The tank with the matching color creates a gap toward Yellow so the soakers can plant there.

Hunter Job: Run toward the entrance, clear the first few orbs in the line, then run toward the middle and take the gate toward the wall once the orbs stack up, using Turtle.

Vertical

The tank with the matching color creates a gap toward Red so the soakers can plant there.

Hunter Job: Clear the first few on the side, then run toward the middle and Disengage or gate through the middle once the orbs stack up, using Turtle.

Soaking

You want the raid soaks to be consistent and low risk. Sending 6 people per soak makes it basically free:

• 2 targeted players
• 2 healers
• 2 ranged, ideally mobile ranged like Evoker or Mage

This should negate the damage, but people should still press personals, because someone will eventually decide not to soak and you’ll be glad you did.

After the soaks, pull the phoenix adds as close to the boss as possible and rotate kicks on them. Missing kicks is one of the biggest wipe reasons on this boss.

Also, some orbs will bounce back toward the boss. Anyone can pop those as long as they match the color, but stop soaking a couple seconds before the next Voidlight Convergence because the color swap timing will one-shot people who keep soaking through the swap.

Infused Quills on Mythic

This is the main Mythic mechanic.

Infused Quills now does splash damage around the person hit. So you need to be vocal about who is soaking and everyone else dodges the circle, even if they are the same color, because there’s no reason to take extra damage. It is always best to soak at the Source of the quill.

Push Timing Into Egg Phase

Do both sets of Radiant Echoes, then push the boss at around 1:50, right after the Voidlight Convergence cast finishes. Pushing too early ruins your egg phase.

Use the gate right as the boss crashes into the ground.

Plays like Heroic, just more punishing if you get clipped by the wrong color. Dodge and pump the egg.

Your goal is to get the boss to 32% or lower here.

As soon as the egg phase ends, the boss casts Voidlight Convergence again and you’ll have a bunch of orbs around the boss that must be popped before they touch him.

Rule is simple:

• Immune players go pop the orbs around Belo’ren, especially the ones coming from the entrance side, because you will be moving the boss there next.
• Everyone else waits for the color swap, and once your color updates, you can help pop safely.
• Boss damage is spiky here, so dropping an AMZ in the middle is a nice safety blanket.

The second time you’re back in Phase 1, the fight gets a bit more hectic. The good news is the RNG simplifies.

Radiant Echoes will spawn at the start, and whatever you get first will repeat for the entire phase.

Horizontal

• The Tank with the matching color makes a gap from the entrance toward the wall, then runs back fast to soak frontals.
• Raid soaks on Blue, and you keep soaking there for the rest of the phase, basically in front of the previous puddle.
• Hunter clears first few on the opposite side, then goes middle and Disengage or gate with Turtle once the orbs stack up.

Both the Tank and the Hunter repeat this every time.

Vertical

• The Tank with matching color makes a gap from Blue toward entrance, then runs back fast to soak frontals.
• Raid soaks on Skull, and you keep soaking there for the rest of the phase, again in front of the previous puddle.
• Hunter clears first few near Skull to create the first gap, then goes middle and Disengage or gate with Turtle once the orbs stack.

Both the Tank and the Hunter repeat this every time.

Quills

During this phase, Quills are everywhere. The key is staying calm and calling Quills soaks clearly.

Also after each raid soak, you’ll get orbs forming a circle around the boss and closing in. Tanks move the boss out of the center of the circle while soaking orbs on the way, everyone else cleans up the rest, then you reposition the boss back.

Kill Timing Goal

It’s recommended to use some DPS cooldowns in this phase. The damage requirement is very light if you reach the second egg burn with everyone alive.

The goal is to skip the third Embers Of Belo'ren cast by pushing the boss to 0% right as he finishes the third Voidlight Convergence.

If you push just after and Radiant Echoes spawn, you need several players clearing both sides and you need a massive gap in the middle, because when the boss dives his hitbox is bigger and touching an orb there will wipe you.

You want to kill the boss during this phase. Play the mechanics cleanly and you should have enough damage to finish the boss.
