A unit with this ability has a chance of attracting a non-exploding 1d6 of Ko-Oni per month, dependent on the turmoil scales and unrest in the province, the value of the ability and whether the End of Culture global enchantment is active.
This ability does not function underwater. There are also some currently unknown criteria which can prevent the ability from successfully summoning oni.
Local value: turmoil * 10 + unrest, cap at 100.
If End of Culture is active, double this value and cap at 150.
Chance to summon a non-exploding 1d6 of Ko-Oni: local value * Oni Summoner value / 100
