Secondly, in Heroes II, djinns have a 10% chance to halve any unit during an attack. This is related to:
1. A ban on djinns being present among a hero's troops in so-called "arena" type tournaments;
2. An offline gameplay tactic that utilizes this ability. In particular, when the djinn's ability triggers against a unit consisting of 1 creature, that creature dies. This is the basis for a tactic that I call the "Catch's method for taking Dragonspire."
