Revised for Season 17

This ingenious system of narrow concealed tunnels doesn't do much to freshen the air, but allows heroes to have their own private way around town!

Construction

• Requirements for the Construction:

• The Ventilation System must have been unlocked with a blueprint:

• Construction Blueprint (common)

• The Portal Lock must have been completed.
• The following resources must be in The Bank and will be used up after completion:

• 10×  Wrought Iron
•   2×  Metal Support
•   2×  Handful of nuts and bolts

• Citizens must spend 45 to complete the building.

• The costs can be reduced to 42 / 40 / 37 / 34 / 29 by Upgrading the Workshop.

Effects

• Completing the Ventilation System provides 20  Defence points for the Town.
• Allows Heroes to enter and leave Town even when the Town Gates are closed.

Notes

• Tamers' Three-legged Labradoodles cannot use the Ventilation System to return items to Town. The Town Gates must be open.
• The Observation platform's teleport still only brings the citizen to the town gates if the gates are closed, the Ventilation System has to be used manually afterwards.
• Using the Ventilation System will negate the 1 cost of entering the town with the Labyrinth built.
• Escorted citizens cannot use the Ventilation System, they have to use it themselves.

Changes

• In Season 16:
  • The rarity of the building decreased from Construction Blueprint (uncommon) to Construction Blueprint (common).
  • Resource costs changed from ×8 ×1 to ×10 ×2 ×2.
• In Season 6:
  • The rarity of the building decreased from Construction Blueprint (rare) to Construction Blueprint (uncommon).
