Hall of Call

The Hall of Call is a special building in Ardheim. In order to build it, you need to acquire 100 small occult scrolls from the Ancient Secrets event. (However, in the reward for building it, you also receive 100 small occult scrolls back, which you then can use for other constructions.) Once built, it can be used to hire new occult troops using Ardheim technology. The Hall of Call requires player level 20 to construct. More details about the Hall of Call can also be found in this official Facebook post.

The gallery below shows the Hall of Call at all different levels.

At level 1, the Hall of Call can build Crimson Blade units. At higher levels, the Gun Crew "Inferno", Troop "Triple blow", and battle star become available. The cost to hire troops is as follows:

Like other production buildings, the Hall of Call can also be used to train the units it produces. For details on the effects and costs of training, please see the individual unit pages. You can also use the Hall of Call to produce upgraded occult scrolls, at the cost of 10 small occult scrolls for 1 occult scroll, and 10 occult scrolls for 1 big occult scroll. These are necessary for higher-level upgrades and production.

The costs and benefits of upgrading the Hall of Call are as follows:
