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.

Strategy Tips
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 in order to attempt to raise it to +7 again. Usually this is done by engraving a single letter with the weapon.
If a non-cursed scroll of enchant weapon is read while confused, your weapon will be repaired of any erosion it has suffered and will also be erode-proofed.
There are only two scrolls with a base cost of 60, scroll of enchant weapon and Scroll of blank paper. Therefore, any unrecognized scroll with a value of 60 is a scroll of enchant weapon.
Enchanting Beyond +7
- a.k.a., Overenchantment
While possible, it is generally time consuming and risky to consider, but in certain cases (such as a Healer with a unicorn horn, an archeologist with Dwarvish mattock, a Knight preparing to be crowned with Excalibur, or those trying conducts) it may be worthwhile. As there is a 2/3 risk of it being destroyed, this is a very, very bad idea to attempt with artifacts. However, as the weapons listed, some may be found in greater numbers, and so vaporizing will not permanently remove the chance.
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.
