Dark gate

The dark gate is the fourth clan support unit available from the Special Arms Factory. Once the Special Arms Factory has been built by a clan, all clan members can use it to build dark gates in the same way as you produce normal supports (although they come in batches of 3). If you leave the clan, any clan supports you have produced will remain in your inventory, but they cannot be used until you join a clan again. (Upgrades also depend on your clan.) To produce a batch of three dark gates, you need 200 ammunition, 1 book of runic spells, and 6 items for rituals, and it will take 3m. These resources can be obtained by completing the Operation "Hope" clan expedition.

At base, the dark gate works similarly to a dark ritual, doing either 200 or 300 damage in an area of radius 5. At start, there is only one pulse, but this can be significantly upgraded.

The upgrades available at the Special Arms Factory are as follows. As with other clan purchases, all clan members can contribute towards the cost of an upgrade. Unlike most support upgrades (but like most ordinary research), each upgrade has multiple stages that contribute. Note: The description for upgrades often does not match the actual effect of the upgrade. The values shown in the table below are the actual benefits of the upgrade.
