Your base is your main operation center. You will find access points to your alliance (access at level 5), your battle center (access at level 7), and away missions (access at level 10), as well as other features like your daily free crystals.
Relic nodes can be used to place relics in your base. These items apply global boosts that benefit your account. For example, the Covenant of Primus relic provides a relic XP boost that increases Commander experience gains.
Note: Relics cannot be upgraded or leveled up, but they can be sold for Gold.
Due to the importance and the vulnerability of your resources, defending your base from raids is a big priority. Place your bots in defense positions to fight off enemy attackers.
Mods can be applied directly to a base node, and when placed, will benefit the individual bots placed on the same node. All mods have abilities that can be improved by ranking up.
Each mod has a tier, rank, and level. You can see this information by going to your BOTS tab on your home screen, then tapping on the MODS tab, and opening the information panel by tapping on specific mods.
Raid shields temporarily protect your base from enemy raids for a set amount of time. Once you have applied a raid shield, opponents will not be able to raid your base until the shield has expired. However, keep in mind that raiding another player will remove your raid shield early.
You can find these in your store, under the SHIELDS tab.
