There is some mechanism by which scrolls of consecration can be used to “ordain” (transform) certain types of monsters into aligned priests.

Assuming a scroll of consecration exists: confused scroll of consecration consecrates your weapon, which blesses and fooproofs it and maxes/increases its enchantment with no possibility of evaporating. Possibly, turn it into an artifact as well.

For variants with scrolls of consecration, the confused effect will remove the graveyard flag from a level if non-cursed, and add it if cursed.
