Per Age 70 Final changes: Blood Lust will provide +10% Offensive Military Efficiency & +15% Higher Military Losses for the caster & +10% Military Losses for the enemy

I know that BL causes 10% additional deaths and additional 15% of own losses on attacks.

And I know that you have the added 15% own deaths on defense, but do you also kill an additional 10% of the attackers army when defending?

Thanks for any insight
