The Upgrade Voucher is a powerful item capable of instantly levelling up a random Island Upgrade category! However, use it carefully, as there is a chance of losing the Voucher incase the selected category is already at max level.
Island Upgrade categories include:
Hoppers Limit
Border Size
Members Limit
Crop Growth Rates
Spawner Rates
Mob Drop Rates
Generator Rates
Vault Slots
Purchasing this item grants you an Upgrade Voucher which can be right-clicked to level up a random Island Upgrade category. View details for each Island Upgrade Category through our Tutorial NPC ingame. All categories have equal chances of Upgrade!
Tip: Save this item for the last few Upgrades as these would be the most expensive ones!
