24jelmer: Back again with another question. I have just got the enchant item spell. I tried it on several items, all failed. Any of you know the chances of the spell working or how to increase the odds? Also, must of my characters have items which have an added bonus such as fire swords or voltage bows, are these items excluded from the spell? The manual isn't clear on this.
Enchant Item will actually work on any item (though some items may not benefit from enchantments). Similarly, Uncurse Item will work on any item (though it doesn't do what you would expect), and Recharge Item will work on any item with at least 1 charge. The only spell that is restricted is Duplication, which will only work on items that can be obtained as random drops; that spell won't work on quest items, for example.
You need to have enough spell points to cast the spell; the cost is 50 *times* the current bonus of the item. So, for example, if you have something like a Fire Sword +10, you will need 500 spell points (+ 50 gems) to cast the spell. Yes, that is a lot of spell points, and it's enough that you might not be able to cast the spell even just after resting. Note that, in some other versions (notably the classic Mac version and the Sega Genesis version), the cost formula is different (plus instead of times), so don't go by videos of those versions.
With the help of fountains, you can easily enchant any item up to +5; getting an item higher requires resting, as there's no fountain that will give you more than 200 SP.
Here's something fun: Get a Max HP Potion (which normally raises Max HP by 512 when used). Now, cast Enchant Item on it; each cast will increase the amount of max HP it gives by an extra 256, so at +5, you get 1792 max HP per use. (You might consider casting Recharge Item to give the item more charges.) Now use the item a few times to get ridiculously high max HP totals. Unfortunately, these potions don't give you current HP, and the max HP will go away when you rest, which is a bit of a problem. (Actually restoring those HP is, for now at least, left as an exercise to the reader.)
(One warning: Don't enchant an item to +63; doing so can trigger bugs, like the item being treated as cursed. Uncurse Item won't remove such a curse; that spell is bugged, and will instead set the number of charges on the targeted item to 1. Then again, I have a feeling that item curses were not properly implemented in the first place.)
24jelmer: Great, thanks for the pointers!
Edit: wow your tips helped me defeat the dreaded cuisinart. Well, defeat, survive their frenzy! Thanks.
Now, if you're ready for a new challenge:
Start a new game, and kill those cuisinarts without winning any other battles first. Yes, I have actually done thins; it takes some knowledge of the game mechanics (much of which has been provided in this thread) and knowing where certain useful things are, but it is, indeed possible.
(Note that the game only supports one save file, so if you want to do this, you might want to back up your save first.)
Edit: Forgot one thing: The Enchant Item spell always works if you have enough SP and Gems to cast it.
