Guide for the Sanctuary: Corroded Decontamination dungeon — three bosses with diverse mechanics: orbs, color phases, positioning assignments, and a final fragment collection phase.
Boss 1 — Devouring Klawfly
An insectoid boss with mechanics involving orbs, marks, and poison. Requires constant positioning control and poison cleansing.
📍Positioning
- Ranged players must constantly monitor their position and move away from the boss in time
- At certain moments, you need to be closer to the stones
- If someone takes lethal damage — priority: safe resurrection, not continuing the attack
- Always keep a large supply of yellow debuff cleansing potions (Healing Potion) and your healers must have a build for removing debuffs and should monitor the team for poison.
🔮Orbs

The boss’s most crucial mechanic — collecting orbs
- Pick up (“eat”) orbs only when they are PURPLE
- It is recommended to determine the order in advance so that without commands, each person takes an orb in their turn.
💡 Tip: If many of your party members have died, you CAN collect more than one orb per person. For this, it’s important to wait until the purple orb above the character’s head DISAPPEARS, and then you can pick up a SECOND one, but NOT BEFORE! In the worst case, it’s possible to collect more than one orb (this will cause an explosion) carefully with a full heal after the explosion!
Boss 2 — Black Blood Blatt
A boss with line and cone attacks, hooks, a strong bleeding DoT, a color phase, and a slime mechanic. Ends with a mass attack that must be dodged.
- Linear Attacks and Pull – watch the floor markers and dodge in time. The boss throws his hook, pulls himself to it, and strikes in a cross pattern.

- Circular Attack with Pull – the boss starts spinning his hook overhead and pulls players towards him. The rings deal damage from the outer circle inward, so it’s crucial to block in time or dodge with a dash!

Slime Mechanic
At a certain point, the boss summons 4 slimes.
Take your positions near the slimes, 2 players per slime.
Either kill the slimes immediately – to avoid them exploding or keep their health around 20-40%! Do not let the boss’s spit hit a slime (this will kill or heal it) and only finish them off quickly when the global red field appears – the precursor to the wipe AoE – as the boss begins casting “Fierce Toxic Aura Wave”.

The boss will also shoot healing (a green bar will warn you about this) which you must collect yourselves, as you will take constant damage near the slimes, and if slime gets fully healed it will EXPLODE and deal dmg to everyone.

⚠️ Warning: Killing the slimes prematurely will lead to your death 100%. But if Clerics survive they can resurrect everyone.
Final Boss — Terminator Bargott
The most difficult opponent with mechanics involving positioning, poison, collecting fragments, and bombs. Requires precise coordination and attention until the very last percent of HP.
Basic Attacks
This boss has extremely powerful abilities that can easily wipe the entire party, so proper dodging or blocking is critical.
- Triple Strike – The boss strikes 3 times with a powerful AoE, in the form of expanding circles.
Can be dodged with a dash, a block, or by staying outside the attack range. - Acid Rain – The boss jumps to the center of the platform, and a red damage circle spreads from the jump (must be jumped over). After that, a purple rain will start falling on EVERY character, which not only deals damage but also leaves a poisonous puddle.
After jumping over the expanding circle, EVERYONE gathers together at the edge of the platform and runs along it so the poison doesn’t interfere with further mechanics. - Split the Damage – The boss summons 3 red fields with arrows pointing inward, one after another. Your task is to split the damage on each one, in the order they appear.
