A team of mages dedicated to researching "complex magical emanations that grant special properties and abilities to a hero equipped with a complete set of artifacts with increased affinity for each other," colloquially known as "set auras," has recorded the appearance in our world of a new type of such emanation, provisionally named "auto-spell."
The first successful experiment in the practical application of this new knowledge made it possible to revive the "Cursed Armor" set, consisting of a Dead Knight's Sabre, a "Dead Maw" Shield, a Bone Helmet, and a Rib Cage. Henceforth, a hero possessing such a set will automatically cast "Slow," "Curse," "Weakness," and "Bad Luck" on the enemy at the expert level during the first turn of their unit at the beginning of the battle.
However, even such interesting news could not distract attentive heroes from rumors that parts of another ancient set – the "Angel Alliance" – are sometimes found in the Great Hoard: a Wonderful Armor, Sandals of the Saint, Divine Necklace of Bliss, Shield of Lion's Courage, Sword of Justice, and even the Helmet of Heavenly Enlightenment itself. The chronicles that have reached us assure that the aura of this unique set increases the hero's attack, defense, magic power, and knowledge by 4; any physical and magical damage dealt by 20%; reduces any physical and magical damage received by 20%; and allows the hero to automatically cast "Prayer" at the expert level during the first turn of their unit at the beginning of the battle.
The same source reports that now, quite different armies await unlucky treasure hunters, but has that ever stopped anyone?
