Garrison Invasions are challenges in your Garrison in Warlords of Draenor that allow you to defeat attacking enemies for rewards.When you kill level 100 mobs (in the areas for Apexis Crystal Quests), you have a chance that the enemies will prepare to attack your garrison in retaliation. The number of mobs appears to be random to trigger an invasion. At this point, your commander by the Town Hall will have a quest for you--this lasts until the next weekly reset, you do not need to complete the quest asap. To start an invasion, talk to Sergeant Crowler or Sergeant Grimjaw. They will have a prompt to prepare to battle a faction. You can have multiple invasions triggered at once.
These are the six types of invasions:
Ogre Invasion!
Shadow Council Invasion!
Shadowmoon Invasion!
Botani Invasion!
Goren Invasion!
Iron Horde Invasion!
These are the internal tracking quests and their associated factions, so you know what areas increase your aggro with these angry factions when you complete an Apexis Daily.
