A question that came up in the blog that never got a reply (that I will quote at the end): when can a redeemer paladin, practically, use their mighty aura feature?
As it is right now you can activate Glimpse of Redemption when an enemy attacks one of your allies to reduce the damage of that one attack. With Mighty Aura you can instead expand that protection to all allies within 15 feet at the cost of a lower reduction.
But under what circumstance does a single attack currently have multiple targets?
I would imagine alchemists fire splash damage would count, (unless they miss?, or target a square instead?).
The other mighty aura effects seem quite powerful, and generally easy to apply, but I can't think of a single instance where mighty aura would be actually do something (other than reduce the potency of glimpse of redemption) at any time throughout doomsday dawn.
Looking at the Paladin changes I want to clarify how Mighty Aura for Redeemer Paladins works.The Glimpse of Redemption reaction's trigger states: An enemy attacks one of your allies or a creature that’s friendly to you. Both the enemy and ally or friendly creature must be within 15 feet of you.
In addition, the Mighty Aura feature states: You can use Glimpse of Redemption to protect multiple allies from an effect that damages several of them. Reduce the resistance granted from Glimpse of Redemption by 2 and apply it to yourself and all allies within 15 feet of you, in addition to the triggering ally.
The intention of this combination seems to be intended for providing allies within 15ft some resistance against area attacks like spells. This seems further reinforced by the Weight of Guilt feat for Glimpse of Redemption that imposes the stupefied condition instead of enfeebled. However because of the way this is worded Glimpse of Redemption should only trigger when the Attack trait is invoked, but most spells aren't attacks, instead relying on spell saves. This feature appears rather limited as a result of his wording. The only times I can see this being useful are for the Barbarian feat Swipe or a splash weapon like Alchemist's Fire. Additionally multi-attacks like the Fighter's Double Shot feat wouldn't benefit from Mighty Aura either since it is composed of two separate strikes.
