-When a Priestess, Mage Builder, Beast Tamer or any of the other builders approach your base, kill them then take your monarch out to resurrect them. You will be able to have the other team's technology.
-Select Taros as a clan/race and build a Temple. Then, build a Mindmage and use it to attack another clan/race's building unit. You will be able to use it as desired. Note: This also works on attacking units.
