Armour, weapons and shields may have enchantments. For example, a +7 broad axe has an enchantment of +7. Each enchant, or "plus", adds +1 to a specific stat:
- A scroll of enchant armour enchants armour and shields.
- A scroll of enchant weapon enchants weapons.
Rings may also display an enchant value, though except for a unique shop vault, they will always be either +6 or +4 (depending on the stat of the ring). They can not be enchanted further. Artefacts come with a random enchantment value and can not be enchanted further.
All enchantable items have a maximum that they can be naturally enchanted:
|Maximum Enchantment Levels|
|Body armour|| +(Armour's base AC)|
0 for quicksilver dragon scales
|Shields|| +3 for Bucklers, +5 for Kite shields|
+8 for Tower shields
|All other armour||+2|
Artefacts are not bound to these limits and may be "overenchanted". Enchantment level can be negative, though items do not normally generate with a negative enchantment, being usually exclusive to artefacts and other very specific sources (such as the Cinder Acolyte background).
- Prior to 0.27's removal of curses, negative enchantments used to be a lot more common (on cursed items).
- Prior to 0.25, stat boosting rings could naturally spawn with an enchantment from 2 to 6, positive or negative. An amulet of reflection varied in the same way, though was always positive.
- Prior to 0.15, weapons had a seperate to-hit enchant and damage enchant (e.g. +8,+6 broad axe). A scroll of enchant weapon I increased the former, a scroll of enchant wepaon II for the latter, and a scroll of enchant weapon III increased both twice.
