This is a promo wonder board for use with 7 Wonders: Armada.
It was first available at SPIEL Essen 2018 at Repos Production's booth.
It was the first wonder board that came without a wonder card, for easy random selection as recommended in the base game rules.
Siracusa's wonder board resource is Glass. It has three wonder stages on both of its sides. It has the special rule that its stages can be built in any order.
The wonders stages grant the following (according to the official rulesheet from the publisher; see link section):
Side A:
Stage 1: The player freely moves one of their Ships one space upward on their Dockyard board. In addition, this step grants 1 Naval Shield.
Stage 2: The player freely moves one of their Ships one space upward on their Dockyard board. In addition, this step grants 3 Victory Points at the end of the game.
Stage 3: The player freely moves one of their Ships one space upward on their Dockyard board. In addition, this step grants 1 Ground Shield.
Side B:
Stage 1: The player immediately gains 6 Coins. All other players lose 1 Coin per Commercial Level reached by their Yellow fleet.
Stage 2: The player freely moves two of their different Ships one space upward each on their Dockyard board.
Stage 3: This step grants 1 Ground Shield and 1 Naval Shield.
