Scroll of enchant weapon
|Base price||60 zm|
|Ink to write||8-15|
|Monster use||Will not be used by monsters.|
The scroll of enchant weapon allows you to increase (if non-cursed) or decrease (if cursed) the enchantment of your currently-wielded weapon. This includes weapon-tools like dwarvish mattocks, pick-axes and unicorn horns. Using this scroll on a worm tooth will instead transform it into a crysknife. +5 or below is safe to enchant. +6 and above may evaporate.
There are only two scrolls with a base cost of 60, the scroll of enchant weapon and the scroll of blank paper. Therefore, any unrecognized scroll with a value of 60 is a scroll of enchant weapon.
If you are wielding a stack of weapons, the scroll will affect all of them at once.
An uncursed or blessed scroll will attempt to enchant your weapon. An uncursed scroll will always try to enchant by one point. A blessed scroll may enchant by more than one point, depending on the current enchantment. If the weapon's current enchantment is +8 or less, the scroll will add 1 to (3 – (current enchantment)/3) points. If the current enchantment is +6 or more, the blessed scroll will behave the same as an uncursed scroll. 
Weapons at +9 and above have only a 1-in-(current enchantment) chance of gaining another point of enchantment.
|Enchantment||Points added by blessed scroll|
|-5 to -3||up to 4|
|-2 to +2||up to 3|
|+3 to +5||up to 2|
|+6 to +8||1 (if weapon does not evaporate)|
A weapon already at +6 or above has a 2/3 chance of evaporating instead.
If a cursed weapon is successfully enchanted by at least one point, it will be made uncursed.
A cursed scroll behaves mostly like an uncursed scroll, but tries to decrease the enchantment by one point instead. Artifacts (except Sting and Orcrist) will resist. A weapon already at -6 or below has a 2/3 chance of evaporating. There is no special treatment of weapons at -9 or below.
+5 is the highest enchantment a weapon can have and not be destroyed when enchanting it further. Because of this, it's common to enchant weapons to +5 and then read a blessed scroll of enchant weapon to try to raise it to +7, although this may only raise it to +6. In this case, there are a few ways of reducing it back to +5 so that another blessed scroll can be read:
- Reading a cursed scroll of enchant weapon. Artifacts resist 90% of the time.
- Engraving one letter, if the weapon is edged. Artifacts don't resist this. Note that athames only dull when they are cursed.
- Hitting a disenchanter. Artifacts resist 90% of the time. Note that engaging a disenchanter risks disenchanting your armor.
- Zapping drain life at it on the ground. Artifacts resist 90% of the time.
While possible, enchanting a weapon beyond +7 is generally time consuming and risky to consider. The possibility of evaporation makes this a very bad idea to attempt with an artifact unless you really don't care about losing it.
The most common way to attempt overenchantment is to use a huge single stack of weapons. Usually this means daggers or lightweight, plentiful projectiles such as darts, arrows, and crossbow bolts from monsters and traps. Projectile weapons benefit more from overenchantment than melee weapons since you can multishot them at high skill levels.
A single scroll of enchant weapon can enchant a large stack at once. This greatly reduces the number of scrolls that you need to get a good amount of +8 or +9 weapons.
- Collect a large stack of daggers (say 200) or whatever stackable weapon you want.
- Rustproof and enchant them all up to +7 with the same number of scrolls as it takes to produce a single +7 non-stackable weapon.
- Split the stack up into four stacks of 50 +7 daggers each, and attempt to overenchant each stack. It is likely but not guaranteed that at least one stack will survive.
- Divide your stack of 50 +8 daggers again into four stacks of 12-13 daggers each, and read another four scrolls on the four stacks to attempt to get a stack of +9 daggers.
- If you want you can even continue enchanting the +9 daggers one by one until you get one to +10, but the amount of scrolls needed to get this far is probably not worth the extra enchantment at this point.
Polymorphing weapons does not change their enchantment. Thus a large stack of weapons can be overenchanted and then polypiled into silver daggers, silver sabers, katanas, or whatever other non-artifact weapon you want.
In certain cases (such as a Healer with a unicorn horn, an archeologist with a dwarvish mattock, a Knight preparing to be crowned with Excalibur, or those trying conducts) it may be worthwhile to overenchant non-stackable weapons. The table below shows how many copies of a given +7 weapon must be risked in order to have a certain degree of confidence that at least one +8/+9/+10 weapon will be successfully enchanted. It is impossible to guarantee, with 100% confidence, that this will succeed. The table assumes that the weapon is already +7 when starting the process.
If you are going to try this, make sure to save at least one of your most highly enchanted weapon. Don't accidentally vaporize all of the weapons you were trying to enchant.
If you do happen to find more than one of a certain weapon, and you don't expect to polypile or blank spare enchant weapon scrolls, it's probably worth trying to overenchant, despite how unlikely it is. Because these scrolls are otherwise only useful for polypiling or blanking, there's no real loss involved.

- In fact, because 3 – (6/3) = 1, the blessed scroll behaves like an uncursed scroll at +6, even though the code refers to enchantments above +9.
