The Expedition game mode is an alternative way to play King Arthur: Legends Rise in a player-versus-environment setting. Players will select a difficulty to do battle with Hero units for various Rewards. Each Hero unit will contain eight different Heroes, and depending on the Difficulty Level of the Expedition, players can create up to five different Hero units. Be sure to have a strong and diverse roster before taking on the most challenging Expeditions!
Each Expedition lasts for 48 hours and is completed when the final boss is defeated. To enter an Expedition, you must use a key. Expeditions involve large eight-versus-eight battles that can only be auto-battled. Damage persists, as your Heroes take damage within their units. However, players will be able to obtain consumable items to help heal and revive their fallen Heroes.
In order to navigate the map, players must select a node, which can contain a variety of situations including battles, resource-gathering events, Arcana events, dialogue events, ect. It does take time for your units to reach a node. Additionally, accessing the Rewards of some nodes takes time as well. Do not forget you can create multiple Hero units, and each one can be doing something that progresses your army forward!
When players achieve a victory, they will be awarded normal Rewards but will also be able to select from three random Arcana buffs that will affect their units for the remainder of the Expedition. These buffs can be incredibly powerful and can synergize effectively with your army, so choose wisely.
Players can also purchase and enhance Crests that can be equipped by their units for increased battle prowess. Players can equip Crests in the EDIT UNIT screen; however, they must be garrisoned in your Castle to do so.
Lastly, as players gain access to Lantern Fuel, they can use it in Expeditions to give their armies stackable buffs that can increase their army's Attack, Defense, and Speed. The more Lantern Fuel the player uses, the more powerful the effect. Make sure to enter Expeditions with enough Lantern Fuel for the fight.
