Was questioned in Beta Testing & Developers said it was “Working as intended”
Because the hero has “revived” s/he hasn’t truely DIED… thus because they are not “Dead” they do not trigger the realm bonus.
The same happens for Tyr who has an “on death” realm bonus but can revive both from Fighter Talent & Special Skill… The Realm Bonus for Tyr will ONLY trigger when he is dead dead dead.
