Order of the Sinking Star's Hardest Chokepoints: Heroes Together, the Water-Walking Rule, Mirror Part 3 and Stones Level 2

This is the wall that defines the mid-game, and it sits in Heroes and Water, the crossover area behind the HxM gold room. After Screen #2, you push the crystal in the top-right corner of the overworld up to open the path to Screen #3 (Top) — and there the area simply ends. Open water on every side. Platforms that do not connect. Every hero refuses the edge, because ordinary heroes cannot step into open water at all. It looks exactly like a missing item.

The missing thing is a rule, and here it is in full: equip the gold cloak, and while a fire monster's flame is actively hitting your character, the water tiles under them are walkable. Step out of the flame's line and the crossing ends.

Why it works is the Priest. In the crossover areas you borrow each hero's power through cloaks worn at area entrances: red pushes, green pulls, purple swaps — and gold is the Priest's cloak. The Priest is protected from monster attacks, dragon breath included. Fire that would kill any other character is survivable for gold, and the game turns that protection into footing: flame contact is the bridge. That is why the monster has to be a fire monster — a ranged breather with a continuous flame stream. Melee contact does nothing.

The technique has a name in the walkthroughs: follow the flame. You do not dash across between breaths. You step into the stream and move with it, staying inside the fire as it sweeps, letting it carry your crossing over the water. Once you see it, you will spot the same manoeuvre elsewhere — it appears in Heroes and Mirrors as well, and later puzzles on this same screen send even the Bard travelling inside a monster's fire.

The game does teach the rule, deliberately: the top-left cluster's Puzzle #1 on Screen #3 (Top) is a pure tutorial whose entire solution is to walk to the teleporter — it exists only to show you that gold walks on water while being hit. Most stuck players brute-forced that puzzle some other way, or solved it without registering why it worked, and then hit the remaining clusters with the lesson unlearned. All four clusters on the half-screen — top-left, top-right, middle and bottom-right, 11 puzzles by the community guides' count — are built on this one rule. Learn it once, and a whole screen opens.

Heroes Together stops players for the opposite reason: every rule at once. First, a precision most guides get wrong — it is not the Heroes campaign finale. The campaign achievement actually pops earlier, at the top-right single puzzle of Heroes 3: Bard, Druid. Heroes Together is what sits directly above Heroes 3: exactly one screen containing one puzzle, a post-campaign bridge. And it matters beyond pride: the puzzle's final button clears a barrier inside the HxS gold room, dropping the gold stone into position. Skip it, and your HxS progress stalls later for reasons that look unrelated.

The exam format is this. The screen has two alcoves, and you work through them — left, then right — wearing a different hero's robe on each pass: green for the Thief's pull, red for the Warrior's push, purple for the Wizard's swap, then the Bard's aura, gold, and the Druid's transformation. Every pass reconfigures the same crystals and monsters, across roughly fifteen staged sub-objectives chained into a single screen.

The set-pieces are worth knowing by name. You park a crystal on a button using Wizard swaps; the Bard's aura drags a melee monster into its twin so the two destroy each other; gold reaches a button that destroys a ranged monster. Then the hardest sequence: the Bard re-aims the second ranged monster, the Druid turns it into a crystal, and the finale has the Bard haul that crystal across the alcove in an aura-drag of roughly thirty inputs onto a second button.

The technique is about temperament: treat every pass as leaving a message for the next one. The late aura-haul only works if every earlier stage was left in its exact intended state — a crystal one tile off, placed two robes ago, fails the finale silently. When the haul breaks down, do not patch forward. Rewind deep, to the stage that placed the offending piece, and redo from there. And if you are truly walled, this is the one chokepoint where a complete verified answer exists in the open: the community-run wikitactics map carries the puzzle as solved, move by move.

The Mirror Isles campaign is usually played in three parts, and the structure is the trap. Parts 1 and 2 are a gentle school: the Trader swaps places with his reflection, one idea at a time, and 72.3% of players finish the campaign — the second-highest completion of the four worlds. Then Part 3, the final six puzzles, arrives, and GameRant's walkthrough flags them as far harder than everything before them. They are right, and the reason is combination. The early parts let each reflection trick take its turn; the final six stack them — multi-islet courses where your reflection's position on a far island was decided by where you stood several moves earlier, and an error in facing or placement compounds quietly until the endgame of the puzzle is already unreachable.

Because no honest shortcut exists for these six, this section gives you technique instead of steps — anyone selling you a Part 3 "solution" in three bullet points is inventing it.

Skipping Stones to Lonely Homes is already the hardest ruleset in the game — 33.1% campaign completion against the Heroes' 86.6% — because its water, currents and drifting lily pads run in real time. Level 2 then adds the multiplier: a second character, and the pair must pass stones to each other across the water. Screens 3 and 4 are where that peaks, and where written guides abandon prose for long numbered step lists — the signature of a real chokepoint.

What stops people here is coordination. A pass is only possible in a window: the receiver has to be positioned, the stone has to travel, and the current is moving the whole time. Most failed attempts share one cause — the player keeps adjusting both characters between passes, so every window arrives with one of them out of place, and a missed pass leaves the stone drifting into the next attempt's way.

The technique that fixes it:

Every wall in this guide has the same emergency exit, and it is the one the game teaches in its first hour: walk away. You are never locked into a world, and a puzzle you abandon keeps its exact state and full move history, across sessions if you like. The completion gap between the worlds — 86.6% down to 33.1% — is mostly four or five missing ideas on a very large map. Ideas arrive while you are solving other puzzles: the flame-following trick clicks while you are doing something with mirrors; the Heroes Together finale makes sense after a night's sleep. Bang on a wall for twenty minutes, then go finish something in another world and let the stuck one sit. In a game with no hint system, the world-switch is the hint system — it is just spelled "later."

Is Heroes Together required to finish the Heroes campaign? No. The initial-Heroes campaign achievement pops at the top-right single puzzle of Heroes 3: Bard, Druid. Heroes Together is the one-screen bridge above it — but do it anyway, because its final button clears a barrier inside the HxS gold room.

Why can't I walk on water with the other cloaks? Because the rule runs on protection. Gold is the Priest's cloak, and the Priest is protected from monster flame and dragon breath — gold is the only character who can be inside a flame stream and survive it. The other heroes cannot step into open water at all, with or without a monster nearby.

Does the monster rule work with any monster? No — it needs a fire monster: a ranged breather with a continuous flame. The water holds only while that flame is actively hitting the gold-cloaked character. Melee monsters, and the gaps between breaths, do not count.

Mirror Part 3 feels impossible. Is it just me? No. GameRant's walkthrough singles out the final six puzzles as far harder than Parts 1–2, and the campaign's otherwise healthy 72.3% completion rate hides how much of the drop-off is concentrated in those six. Work backwards from the teleporter and audit the reflection's placement before your own.

If I leave a chokepoint puzzle, do I lose my progress in it? No. The puzzle keeps its state and its full move history, even if you close the game. Switch worlds, solve something else, and come back — the wall will be exactly where you left it, and you will usually be better at it.
