Storm Shield

Storm Shield
The Storm Shield, or "Homebase", is a map where players can build their own personal, permanent base. Players can enter their Storm Shield to build or store items at any time, and building progress will be saved even if the player leaves the mission without starting the defense phase. Players have a separate Storm Shield in each map location.

Storm Shield Defense
Storm Shield Defense is one of the main quest series that players must complete in order to progress through the game. Each map location has 10 Storm Shield Defense missions, 6 of which are Main Quests. Completing Storm Shield Defense missions increases the range of mission power levels available to the player.

Amplifiers
Amplifiers are devices that amplify your Storm Shield’s power. There are A, B, C and D. You must defend them from Monsters.

Storm Shield Storage
In addition to the player's inventory, which is accessible during missions, players have a separate storage location in their Storm Shield that is only accessible while inside the Storm Shield map. While the Storm Shield base is unique to each map location, the player's storage inventory persists between locations. This storage starts with only 5 storage slots, but the number of slots can be increased through the Upgrades section of the Command Tab.

Defender Squads
Players can designate up to five Defenders per map location to be summonable in that location's Storm Shield. These defenders do not count towards the regular 4-player cap that Mission defenders are affected by, therefore up to five Homebase Defenders may be summoned in addition to a full team of players or Mission defenders. Therefore, it is possible to have up to eight defenders in a Storm Shield Defense mission if a solo player summons all five of their Homebase defenders in addition to their three available Mission defenders.
