'Sacrifice of Loyalty' Undying Hate keystone grants increased damage instead of more.

I reverse-engineered the power of reviving skeletal minions as being 0.5 power each. With no tree or gear damage increases, 20 skeletons grants 10% extra damage for all player skills.

As soon as you add player increase scaling however, the relative boost from Sacrifice of Loyalty goes down rapidly, which leads me to believe the boost is an increase instead of the listed 'more damage'.

Furthermore, temporary minions such as Zombies and Unearth crawlers do not provide any damage boost toward the effect of the keystone, despite being undead minions. If the effect was designed to only work on persistent/reviving minions, it should state as such on the keystone's description.
