I know Spy def is what prevents spy actions, but if you have adt do you lose less troops by assn aswell as Atk? Or no effect?
No, adt doesnt affect assass. Spy defense level / static determines troop loss, i tested this on my alts. I can tell you the figures later on.
Your total troop number would be lower so in pure numbers yes, however in real terms the loss from an assass remains the same. Same percentage of troops killed regardless of ADT.
