To summon a yoggar-shuaba, a demonologist must sacrifice thirteen innocents in a complex ritual, using intricate demonic spells in the most ancient forms of the demonic language, including one of the Forbidden Words. The summoning circle must be fashioned with a pen dipped in demon's blood, burned into solid stone (preferably a stone like granite). The circle will not hold the yoggar-shuaba's physical form, but open a gate to the demon to allow communication. The standard contract with a yoggar-shuaba is for strength, intimidating presence, eternal life, and/or power over the meek. The standard cost is a steady supply of mortals to be eaten. Special contracts are possible but rare, and the cost is always the same.

To bind a yoggar-shuaba, one must have incredible esoteric power, usually imperium. A blackiron chain wrapped around the finger of a yoggar-shuaba (it is unlikely one would have enough blackiron for more) can, if powerful enough, bind one. Enslavement is risky but possible. Drawing power is possible if the chain is properly designed. Binding into an object is very, very difficult, as it requires converting so much mass into infernal energy. To do so, one must chain a yoggar-shuaba with a blackiron chain designed to drain their power, then wrap the chain around the target object (or person). The object or person must then have the strength or will to survive the process. This will give the object or person immense infernal power, but it will likely eventually destroy them.

No one but an infernal Divine can create a yoggar-shuaba.
