About The Dread Cellar Dungeon
The Dread Cellar dungeon contains three main bosses and three secret bosses. Each main boss has a hard mode that you can activate which you’ll need to complete each subsequent hard mode if your goal is to finish all the hard modes in the dungeons.
This dungeon is also compromised of three secret bosses each granting a special buff that remains with you throughout the instance. You can use a synergy after you’ve obtained the secret bosses and summon them to your aid for one minute during the fight. It’s highly recommended you do all three secret bosses if your goal is to complete all hard modes, as they are extremely challenging without the buffs.
Accessing the Trap Doors
Step 1: access the trap door via acquiring two-four braziers with the synergy key. Deposit each brazier and gain access to the secret boss.
Step 2: you’ll need to simultaneously activate crystals in order for a portal to spawn allowing you entrance in the secret boss area.
Step 3: grab two more braziers and place at each crystal in order to unlock the boss fight. Kill the boss in order to given their buff along with the ability to summon them in subsequent boss fights.

Boss 1 Scorion Broodlord
Main Boss #1
This is the first boss boss in Dread Cellar
- Health: Veteran 2,525,979 and Hardmode 8,571,372
- Basics: this is the first boss and very hard for melee DPS. It also has hard hitting heavy attacks and damage over time attacks. It’s highly recommended to bring some type of purge or cleanse for negative status effects if possible. Additionally, you can hit the pylon (crystal) in the corner of the room assuming you’ve completed the first secret boss. This will resurrect fallen comrades and give you a boost in DPS.
- Additional Enemies: Every few percentage of health, the boss will continue to spawn additional enemies. Up to four at a time which can be burned down on top of the boss or on top of the ranged enemy.
Basic Mechanics
- Agonymium Stone: boss will shoot up into the sky, summon this at random throughout the area. This is priority target as it will consume and heal the boss.
- Excruciating Expectoration: a hard hitting damage over time effect and will be a problem for the tank to deal with. Prepare for this and reduce bosses damage and save an defensive ultimate if needed.
- Turmoil: AoE conal, make sure the tank points boss away and DPS/Healer are behind.
- Torrent of Turmoil: AoE circles that do decent damage which will go out in 360 degrees. Do you best to avoid them.
- Crush: a hard hitting heavy attack that the tank should be the one to block and tank.
- Pull & Explode: If you leave the area where the boss is, this mechanic will suck everyone in and do damage.
Hardmode Mechanics
- This gives the boss more HP and more frequent additional enemy spawns. You can stack up the boss along with the adds on top of the Agonymium stone to make it easier, but be prepared for constant enemies and damage.
Boss 2 Cyronin Artellian
Main Boss #2
This is the second boss in Dread Cellar
- Health: Veteran 2,873,301 and Hardmode 9,324,750
- Basics: this boss has a lot of mechanics some of which require mobility and can be very difficult if you are not able to dodge roll frequently. Additionally, you can hit the pylon (crystal) in the corner of the room assuming you’ve completed the first and or the second secret boss. This will resurrect fallen comrades and give you a boost in DPS.
Basic Mechanics
- Storm Atronachs: these hard hitting, anti-melee mobs cause a ton of area damage and have a small window to bash and intreeupt. You can destroy them but they will return so clump together on top of the boss whenever possible to kill multiple.
- Boltwyrm: these will tether to a specific player at random and need to be damage be whoever is tethered (even tank) as they will take more damage. Destroy them quickly otherwise you’ll most not likely survive.
- Staff Strike: simple heavy attack that leaves down a AoE damage effect. Be careful where to park this.
- Soulstorm: this will be a one shot via a massive red skull from the center of the boss. You must dodge this and I suggest going further back to help with detection.
- Dread Surge: red waves that flow throughout the room. I would not suggest dodging them as sometimes you die and sometimes you do not. Simply look for the NPC to put up a shield wall and park the boss on there.
Hardmode Mechanics
- This gives the boss more HP and another mechanic which is a debuff that places a negative ground effect on you and will kill if you remain inside.
Boss 3 Magma Incarnate
Main Boss #3
This is the third and final boss boss in Dread Cellar
- Health: Veteran 4,125,765 and Hardmode 15,567,056
- Basics: this boss is one of the most difficult in the game and a nightmare on Hardmode. It’s highly recommended to specialize in “tanky” sets, skills and playstyle until you learn the fight. You will need mobility, survivability, and with 15 million HP, a lot of concentration
Basic Mechanics
- Unstable Blitz: a hard hitting attack that should be avoided.
- Dancing Flames: simple AoE fire tornado that moves about. Simply avoid it best you can.
- Catastrophe: targeting multiple players will shot out and hit you with a hard hitting DoT. Try to dodge roll this after roughly 3 seconds though it’ll take some practice. Also don’t stand onto of each other!
- Frenzy: simple heavy attack that needs to be blocked or dodge pending stamina.
- Portal: around 70%/35% health, the boss will become immune to damage and you’ll need to run into the back of the room. Here, you’ll need to use a synergy in kill a crystal inside. Otherwise it’ll empower the boss and be very difficult to deal with.
- Path of Fire: hard mode will leave a pool of fire, because why not?
Hardmode Mechanics
- This gives the boss a lot more HP and two mechanics. One, outburst is a yellowish circle that the tank needs to stand in and block otherwise you will die. Tornado wall which will swirl around the room and you can huge the center to avoid it.
