It is worth noting that Mara's Wrath only affects hostile targets, and will not deal damage to friendly NPCs. Except for NPCs who have the   keyword attached and a level that is low enough to be affected by the Turn Undead Fear effect of Mara's Wrath, such as Sybille Stentor, which if true will initiate combat and may result in a bounty for assault.
Mara's Wrath has both the   and   keywords attached. This means that the   and   hidden quests will trigger when the spell is being cast and when it is active, respectively. This results in nearby bystanders making comments on the magical antics.
The Skeletal Dragon cannot be affected by the Turn Undead Fear effect of Mara's Wrath.
Unlike Flame Cloak, having Mara's Wrath ready to cast does not ignite flammable gas.
Mara's Wrath first appeared in the Spell Tomes official add-on for The Elder Scrolls IV: Oblivion.
