Mechanics

You will receive a demonic guardian when the following condition is met:

   (3/4)*tension > mutlevel*6 + 1d(2*mutlevel*mutlevel) - 1

Note that this check occurs every turn, until a guardian is summoned. Thus, the random factor simply makes summons take longer for 'middling' tensions.

After receiving a guardian you will not receive another one for another (1+mutlevel) to (20+mutlevel) turns. Guardians have a 2/3 chance of vanishing each turn if tension drops below the requisite amount required to summon them, although they are guaranteed to exist for 4-7 turns. The guardians always spawn friendly, but will be angered if you attack them. Hostile guardians will not unsummon.
