Use of the skill attack uses ALL of the Morale (check out monsters next time, no morale left even when bar is red ie 200+ morale). Wearing all 6 pieces of Hope Bringers set lets you retain 35 Morale not 35%. I thought it was 35% at first then I looked at what it really said and that is "Retain 35 Morale after skill attacks". I personally do not want the monsters to be able to fire of skill after skill attack, though I see an advantage for me being able to do so
. Best suggestion find another hero with the same skill and stagger their initial Morale.
