A tower route that separates damage growth, poison delivery and the time needed to attack.

Working attacker and protection → tower damage → connected Cauldron → control as required.

B3 Cauldron is adjacent to B2 Trebuchet, not C2 Ballista. Poison on Ballista requires moving Cauldron to C3 or another cardinal neighbor. Current Cauldron grants three poison stacks per level.

Best for

A tower route that separates damage growth, poison delivery and the time needed to attack.

Avoid if

Adding poison where no attack delivers it, or spending too much on supports while the army lacks immediate contact time.

How it works

Trebuchet has area-damage projectiles under the deck rework. Quarry grows tower damage; Cauldron grants adjacent recipients poison. Control or screening makes those attacks useful before enemies reach the base.

Equipment priority

PriorityEquipmentInstruction
1 · StabilizeTrebuchet with a poison-capable attackerPut an attacker that contributes now onto the board. Trebuchet is the tower commitment, while Ballista can supply a useful troop role if the tower route is incomplete. Wallmaker is conditional protection/control; verify whether it delays the threat actually causing the loss.
2 · ConnectQuarry, Cauldron, WallmakerConnect Cauldron at B3 to Trebuchet at B2, then check that attacks deliver poison to useful targets. Quarry supplies tower damage under its own card text. Do not infer that every support follows Cauldron adjacency, or that a tower-growth effect also develops Ballista.
3 · DevelopPoison Vial only on a valid troop alternativeTrebuchet has area projectiles under the rework. The Cauldron connection adds a separate poison route, while Quarry develops tower damage. Their value depends on attacks happening before the enemy reaches the base. If Ballista becomes the poison recipient instead, re-plan Cauldron adjacency rather than retaining the tower diagram.

Build order

How to play

If poison is not delivered before the army collapses, stop buying more poison support and repair useful attacks or contact time. If hits are delivered but too weak, develop tower damage. This higher-pressure framework has no measured difficulty-clear claim, so an old King IX screenshot is not a stop-loss rule.

What can break the build

Cauldron at B3 is diagonal to Ballista at C2. That arrangement can support B2 Trebuchet but does not establish the intended Ballista link. Move Cauldron to C3 if Ballista needs it, checking the remaining tower relationships before the move.

Trebuchet, Quarry, Cauldron, Ballista and Wallmaker belong to Stone. Nothing or other kings can supply a replacement screen when offered.

Opening: A1: Stronghold; B2: Trebuchet; C2: Ballista

Put an attacker that contributes now onto the board. Trebuchet is the tower commitment, while Ballista can supply a useful troop role if the tower route is incomplete. Wallmaker is conditional protection/control; verify whether it delays the threat actually causing the loss.

Working attacker and protection → tower damage → connected Cauldron → control as required. Treat the order as a reward decision, not a promise that those cards arrive together.

Mid-run connections

Connect Cauldron at B3 to Trebuchet at B2, then check that attacks deliver poison to useful targets. Quarry supplies tower damage under its own card text. Do not infer that every support follows Cauldron adjacency, or that a tower-growth effect also develops Ballista.

A–C are rows; 1–3 are columns. Plot cards only; unlocked land required.

A mistake worth avoiding

Cauldron at B3 is diagonal to Ballista at C2. That arrangement can support B2 Trebuchet but does not establish the intended Ballista link. Move Cauldron to C3 if Ballista needs it, checking the remaining tower relationships before the move.

When to stop investing

If poison is not delivered before the army collapses, stop buying more poison support and repair useful attacks or contact time. If hits are delivered but too weak, develop tower damage. This higher-pressure framework has no measured difficulty-clear claim, so an old King IX screenshot is not a stop-loss rule.

Substitutions and a supported pivot

Use Ballista as an available attacker while the tower plan develops, or borrow an ordinary screen when the current protection fails. Poison Vial applies to a valid troop alternative rather than a permanent tile. Do not force a second incomplete damage engine when a duplicate on the active attacker solves the next fight.

If hits are too weak, Quarry can serve the tower; if targeting is the issue, another multiplier alone may not fix it.
