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.

Effects
If wielding a stack of weapons, the scroll will affect all of them at once.
A noncursed scroll will attempt to enchant your weapon. An uncursed scroll will always try to enchant by one point.[1] 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[1]. If the current enchantment is +6 or more, the blessed scroll will behave the same as an uncursed scroll.[2] [3]
Weapons at +9 and above have only a 1-in-(current enchantment) chance of gaining another point of enchantment.[2]
| 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.[4]
If a weapon is successfully enchanted by at least one point, it will be made uncursed if it was previously cursed.[5]
A cursed scroll behaves mostly like an uncursed scroll, but tries to decrease the enchantment by one point instead.[6] Artifacts (except Sting and Orcrist) will resist.[7] A weapon already at -6 or below has a 2/3 chance of evaporating.[4] There is no special treatment of weapons at -9 or below.
Trying to enchant a worm tooth will instead turn it into an unfixed noncursed crysknife.[8] Trying to disenchant a crysknife will turn it into a worm tooth.[9]
Reading a noncursed scroll of enchant weapon while confused will erodeproof your weapon and fix any existing damage.[10][11] A cursed scroll will remove the erodeproofing instead.[10]
If you read a scroll of enchant weapon without wielding a weapon or weapon-tool, you will exercise your dexterity instead (or abuse it if the scroll is cursed).[12]
Standard Strategy
Since enchanting a weapon when it is already above +5 runs a 2/3 risk of it being destroyed, it's common to enchant weapons to +5 and then read a blessed scroll of enchant weapon to raise them to +6 or +7. Often players will lower a +6 weapon to +5 to attempt to raise it to +7 again.
Lowering of enchantment can be done in various ways. For edged weapons only, it can be done by engraving a single letter, artifacts don't resist this. Specifically for athames, they can be dulled by engraving only when they are cursed. Reading a cursed scroll of enchant weapon while wielding the weapon, artifacts will resist most of the time. Hitting a disenchanter, more reliable then the cursed scroll for artifacts. Drain life spell, artifacts will resist most of the time.
It's possible to safely over enchant to +8 a single/stack +7 weapon by wielding it when crowned. However, the penalty of crowning is an extended prayer time out, and can be done only once.
Take note, that enchanting Magicbane above +2, reduces some magical effects while still increasing total damage.
Over enchanting strategy
While possible, enchanting a weapon beyond +7 is generally time consuming and risky to consider. As there is a 2/3 risk of the weapon(s) being destroyed, this is a very, very bad idea to attempt with artifacts.
The right way to go about overenchantment is to use a huge stack of weapons. The most common targets are daggers for throwing, and lightweight, plentiful polyfodder such as darts, arrows, and crossbow bolts from monsters and traps. Projectile weapons benefit more from overenchantment than melee weapons since you can throw more than one per attack.
A single scroll of enchant weapon can enchant a large stack at once. This greatly reduces the number of scrolls that you need. You can collect a stack of (say) 200 daggers. 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. Then you split the stack up into four stacks of 50 +7 daggers each, and attempt to overenchant each stack. At least one stack will survive and become +8 with >80% chance. Now you have a stack of 50 +8 daggers. Divide it again into four stacks of 12-13 daggers each, and read another four scrolls on the four stacks to get (with high probability) 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 most of the time a stack of +9 daggers is good enough.
An even larger stack of darts can be overenchanted and then polypiled into silver daggers, katanas, or the future Excalibur, Sting, or Orcrist.
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 the odds of getting at least one +8/+9/+10 weapon and how many copies must be attempted for the given level of confidence. The table assumes the weapon is already at the +7 level, when starting the process, working to higher levels.
| Bonus | +7 | +8 | +8 | +8 | +8 | +8 | +9 | +9 | +9 | +9 | +9 | +10 | +10 | +10 | +10 | +10 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Confidence | — | 50% | 75% | 85% | 90% | 95% | 50% | 75% | 85% | 90% | 95% | 50% | 75% | 85% | 90% | 95% |
| Attempts | — | 1.71 | 3.42 | 4.68 | 5.68 | 7.39 | 5.88 | 11.77 | 16.11 | 19.55 | 25.43 | 35.08 | 74.16 | 101.49 | 123.18 | 160.27 |
Where the number of attempts is equal to copies of weapons expended. The confidence level, in the second row, how likely it is at the number of attempts (where 50% means half the time, and 95% means 19 in 20). It is mathematically impossible to be 100% confident.
If a player wishes to attempt this, take a given item and enchant it to +7. Drop it on the ground. This is the marker. Enchant various ones to +7, and attempt to get +8. Once one is +8, stop, and drop it on the ground. This is the new marker. This process can be repeated once more to +9, but shouldn't be attempted any further. The gist of this is to have a checkpoint or marker to fall back to in the case that they all vaporize.
In this way it becomes slightly more accessible than the table would otherwise indicate. One thing to consider, if one is not expecting to polypile nor blanking spare enchant weapon scrolls, is to attempt despite how little the odds are if the player has more than one of a given weapon, being quite careful never to vaporize the last copy. As these scrolls are otherwise only useful for polypiling or blanking, there's no real loss involved in this case.
Finaly, you can safelly add a single extra +1 on your over enchanted weapon with crowning, with the corresponding disadvantages.
