Scrolls of enchant weapon

Version 0.13: This article may not be up to date for the latest stable release of Crawl.

Type	Scroll
Name	Scroll of enchant weapon I, II, III

This scroll places an enchantment upon the wielded weapon, making it more accurate in combat. It becomes increasingly less likely to succeed when used on highly enchanted weapons, and can only ever enchant them up to +9. Magical artefacts cannot be enchanted at all. "To drift with every passion till my soul Is a stringed lute on which all winds can play, Is it for this that I have given away Mine ancient wisdom, and austere control? Methinks my life is a twice-written scroll Scrawled over on some boyish holiday." -Oscar Wilde, Helas. 1881.

Reading any of the scrolls of enchant weapon will attempt to permanently enchant your currently wielded weapon to be more effective in combat, and will uncurse it if it is cursed. The enchantment effect of these scrolls will sometimes fail if the wielded weapon is already enchanted above +3, and will always fail if the weapon is enchanted to +9 or if you're currently wielding an artefact weapon, a magical staff, a rod, a deck, a non-combat item, or nothing (you can't enchant your fists). Successful enchantment will be reported as the weapon glowing, with different effects and colors for each of the three varieties:

• Enchant Weapon I: Glows green, increases accuracy by up to +1.
• Enchant Weapon II: Glows red, increases damage by up to +1.
• Enchant Weapon III: Glows yellow, increases damage and accuracy by up to +1d2

The message you receive upon reading depends upon the following:

On Success: Your [weapon] glows [color] for a moment.
On Failure: Your [weapon] very briefly gains a [color] sheen.
Used to uncurse an artefact: Your [weapon] glows silver for a moment.

The chance of any given scroll successfully enchanting your weapon can be seen below:

Current Enchantment	-5 to +3	+4	+5	+6	+7	+8	+9
EW I or II: Chance of +1	100%	56%	44%	33%	22%	11%	0%
EW III: Chance of +1	50%	52%	46%	38%	28%	15%	0%
EW III: Chance of +2	50%	15%	10%	5%	2%	0%	0%

Raising your weapon's damage enchantment level also improves its ability to resist corrosion - the higher the enchantment, the better its ability to resist, reaching 100% immunity at +5. Bear in mind that your weapon's accuracy enchantment level has no effect on corrosion.

Regardless of success or failure, reading a scroll of enchant weapon will identify it, though each of the three types must be identified individually.

Strategy

• Although it's tempting to save these scrolls up until you find the perfect weapon, you shouldn't be too stingy with them. A general good practice is to enchant whatever weapon you're currently using up to +4, only going past that for the weapon you intend to use for the rest of the game. This avoids wasting too many scrolls on weapons you'll eventually toss without crippling your ability to survive early on.
• Some treasure troves require you give them a weapon with a certain enchantment level to gain access. While these weapons may occur naturally, it's often easier to find an appropriate weapon and enchant it yourself. Usually, if you save the majority of your scrolls for an endgame-quality weapon, you'll know whether or not you're dealing with a weapon-demanding trove by the time you want to use your scrolls. The contents of a trove are usually worth the investment, though this is by no means guaranteed.
• Using these scrolls to uncurse your weapon is extremely wasteful, as scrolls of remove curse are common and can uncurse multiple items at once. Do so only as a last resort.
