I think that Hafaada might not be necessary in this case.
Alternatively, we could try to rethink similar abilities to make them easier to implement. For example, instead of killing a percentage of units, we could reduce the health of all units by a percentage (I'm not sure if this specific idea would work, but it demonstrates the thought process).
Or, we could actually make summoned units attack the enemy army, but without calculating percentages of units to kill, and instead use different rules.

Here's an idea: have a creature attack enemies with a damage range of 1-1 with a guaranteed hit, to ignore the defense of units. In this case, we can calculate the damage quite accurately; the only variable we can't know in this case is the additional health from minions. On the other hand, this situation is relatively rare overall. Battles against enemies with minions are rare in themselves, and the additional health from minions doesn't create a significant error for all creatures of the Academy. In the case of Hafaada, it only applies to gremlins and mages, which is a truly rare case, and I think we can create a separate solution for it, even if it's not very visually appealing.

In any case, there will initially be compatibility with NHF without any changes; then I'll think about it and test different options.
