Absk, Adef, Amdf, ANms, AEim, AHds (Berserk, Defend, Magical Defense, Mana Shield, Immolation, Divine Shield): These abilities don't stop the current order of the caster when used. The last five can be activated and deactivated (if that is enabled in the gameplay constants). The mentioned abilities can easily be customized by setting their effect to zero and catching their order and unorder string. You'll eventually have to remove the buff with the 'UnitRemoveAbility' native after catching an order, if you don't want buffs to show up on the unit. However the unorder is issued twice when these abilities are removed from a unit. Therefore you need a simple workaround to not catch these unorders.
