Lord of Mysteries Clown Boss Guide (2026): Antigonus Dungeon

The opening minute is a pure damage check with one rule. When you see lines drawn under your character, position so the resulting area attack does not overlap a teammate — the mechanic punishes clustering, not the player holding it. The four violet plates ringing the stage in this frame are the boss's own markers.

When the large orange circle appears, the whole party gathers inside it to share the damage. On Normal difficulty this attack does not hurt much yet — the creator stresses that it will on the harder difficulties, so build the habit now rather than learning it under pressure. The "snatching Sealed Artifact" line in this frame is the boss's own flavour text over the same cast.

When the boss spawns doubles, every DPS player prioritises them. The objective banner in this frame is the rule written by the game itself: defeat all the doubles to interrupt the research. If you fail to clear them in time, the run's failure risk rises sharply because the boss will not break out of the sequence.

Killing the full set pays off immediately: the banner flips to "Successfully defeated the doubles", and the boss is enclosed for a fixed window. That window is your burst phase — the party in this frame is already stacked on the boss with damage numbers running.

The Card Juggling cast is one of the boss's repeating attacks, announced by the "Juggling time! Dangerous stunts, please do not imitate." line. It does not add a new requirement — the party keeps its rotation and stays out of the falling cards, which is why the stacked formation in this frame is safe here and unsafe during the doubles wave.

Later waves bring shadow doubles and ground pools that keep ticking after they land. The same priority applies — the adds first, then the boss — and the party has to break the stacks to stay out of the pools, which is what the spread in this frame is doing.

The curtain is the transition the whole fight builds to. The stage goes dark, spotlights sweep in, and the announcement "The curtain rises, the show begins!" fires. Keep using your skill rotation during it — the creator emphasises that the abilities are still available, so the curtain is a positioning phase, not a downtime phase.

Each player gets a card symbol overhead. You have to move your character onto the matching suit plate — the on-screen instruction in this frame reads "Quickly enter the area corresponding to your card!". Positioning wrong is not a damage penalty; the creator states plainly that this attack can instantly kill you.

The check is not instant. The fire ring around each plate has to complete before the boss evaluates whether you are standing in the right place, which is the window you use to finish a rotation or cross the stage. Air Missile fires during this stretch, so the crossing is not free.

The stage itself is the map: hearts, spades, clubs and diamonds are engraved into the floor in fixed positions, and the golden gate arches mark the edges of the plates. Parties that memorise the geometry stop hunting for their symbol under pressure, which is the difference between passing the check and being erased by it.

After the mechanics, the fight is a damage race. The creator's figure is a minimum of 4,200 DPS per team member, and he notes that parties clearing the second boss already have a useful reference point for whether they are close. The numbers in this frame are what a passing party looks like mid-rotation.

The mechanic list never grows. What grows is the damage on each repeat — the creator points out that on most bosses in this game the second and third rotations hit harder, and the Clown follows that rule. Late-stage frames look identical to early ones except for how little room the party has for a mistake.

The results screen from this run: Brilliant Stars rating, 1,568,443 total damage, and the Abund Closure timing badge, followed by the group auction window listing the sealed-artifact materials and their starting bids. This is the frame to compare against your own attempt when you are deciding whether the party is ready to stop practising and start racing.
