NHF – new heroes for Heroes V 3.1.

Agraal initially had the same aura, so it would be better to restore it to him. By the way, in your mod, the aura works differently. In the vanilla version, each level gives 1% to initiative, but in your mod, it's immediately 15%, which means it can be adjusted. So, you could give this aura to heroes who have the "Lord of Initiative" skill. An initiative bonus only for the hero himself is still better and not as overpowered as a bonus to initiative for the hero and a simultaneous reduction for the opponent.
