With the new update to the game, 4th cities can be runecrafted, and runecrafting up to level *11 is finally possible, although a pain in the ass. Just think about the number of Hobbit Runecrafters you need to to be able to train all Tier 4 units and then think about how available these things are to get your hands on. But I think it is a great time to go over the topic of forging runes, the runes you need to get to level *10 in the first place.
So where do you get these runes? What do you use them for, and how? Which trade from the Sage tower is most profitable? And how many do you need to upgrade your buildings. In this post, I will try to combine all available information on the topic.
Like mentioned in my post on update 9.1.0, it brought to the game the exciting new feature of Alliance Boss Battles.
At the time of writing that piece, the feature had not been fully implemented yet, but it has in the mean time, and it is such an addition it merits its own article. So here, I will lay out all the necessary information you need about this feature.
