Permanently unlocks the Poison island theme on your account. Once it is yours, you can choose Poison whenever you create a new HomeWorld island, or re-theme an island you already own — any island can be re-themed once every 24 hours. The unlock itself never expires, and clanmates building on your world can pick it too.

What it changes: the island is rebuilt as a sunken swamp of murky water and creeping growth, centred on a bubbling Cauldron, with a Crobat statue spread above it. Terrain, plant life, water, weather and ambience all change with the theme. Re-theming keeps your builds and everything stored on the island — they are lifted clear and set back down on the new ground.

This is a one-time unlock. You only ever need one — a second copy of the same theme adds nothing, so please don't buy it twice. Delivered in-game within moments of purchase.
