That Immortal is completely out of place in Bright Forest and makes no sense whatsoever. The artwork goes with Shentang, but the troop typing goes with Pridelands. But it’s not like the devs listen to any feedback like this, so who cares.
Maybe there are lots of mice to catch in Bright Forest and Khaomani wants them all to herself.
From a logical standpoint, yes. All the other Immortals have the same kingdom as their weapon. But here is a fun fact that we discovered when these troops were first introduced–We can’t use Terra’s Jewel in Southwild because we can never have a restriction there. That’s just…dumb. (And we would have to get people to vote for that restriction anyway).
There are a lot of things in this game that make no sense, and I have learned to accept it. They don’t care.
