To participate, members of the League must take a Slot in the League Attack itself. The first Slot will always be taken by the League initiator, with two more Slots open automatically. Additional Slots can be opened individually with Sapphires, or all Slots for one Attack can be opened at the same time with the Slot Unlocker (All Slots, 1 League Attack) Item.
Once a player has taken a Slot, they must select the Units they want to take part in the Attack. These Units will need to travel to the initiator’s Castle in order to be ready for dispatch. Any Units that do not arrive in time before the dispatch timer runs out will be returned to their home Castle and will not contribute to the final Attack result.
Note: Certain Stoneheart Abilities - when activated - will benefit every League Member’s army in the Attack. Stoneheart Abilities from League Members joining another player’s League Attack will not be activated unless the initiator has unlocked their Stoneheart Castle. Information about Stoneheart Unit Abilities will be only available to League Attack initiator.
