Gating
This is a unique Demonic ability which allows your troops to call for additional reinforcements right on the combat field. The amount of troops summoned directly depends on the numbers of the summoning stack. Any demonic creature led by a lord is able to gate a stack consisting of 20%+4%*[Demon skill level] creatures of the summoning stack. This ability is extremely useful against neutral creatures. You will be able to distract enemy troops with the summoned armies and destroy them with your main forces, use magic or simply run them over with everything you've got.
Gated stacks disappear after combat. Note that if only gated creatures are left, the Demon loses the fight immediately, as if he or she didn't have them at all.
in other words, it is just luck. but the chance is increased with a higher racial skill |
