Scroll of Enchant Weapon
From The Unofficial POWDER Wiki
Enchants (or disenchants) the weapon in your main hand by providing a +x to its attributes. If the scroll is cursed, the weapon will get a -1 malus. If the scroll is normal, the weapon will get a +1 bonus. If the scroll is blessed, the target item will receive +1 or +2 (50/50 chance).
"[a weapon] glows dull brown" is a -1 malus.
"[a weapon] glows silver" is a +1 bonus.
"[a weapon] glows bright silver" is a +2 bonus.
Weapons can be enchanted up to +5, after which point you receive the message "[weapon] shudders!". Trying to enchant it further may cause it to break (if it goes above +7). However, deities may still enchant the weapon further without breaking it.
