Soldak Entertainment - Dungeon Crawl Item System
Soldak's Steven Peeler has blogged about the item system in their upcoming "hardcore" dungeon crawler. Starting with the Depths of Peril system as a base, they've expanded from there, such as cursed items:
Cursed items are going to make things interesting. No they are NOT like D&D cursed items that bind to you if you equip them. A cursed item has at least one negative attribute, like a strength penalty. I think the cursed items are going to be amusing in many cases and add a lot of variety. Is that cool rare sword with the curse better than your merely common magic sword?
The positive side of cursed items is that they have lower level and attribute requirements to use them. So thanks to the curse, you might be able to use an item that is well above your level. Many times a curse will be bad, but sometimes it will be a blessing in disguise. It also lowers the item price which will be good or bad depending on if you're buying or selling. Some possible pure cursed items: axe of flabbiness (less vitality), staff of lameness (less spirit), mace of impotence (less strength), long sword of the Idiot (less intelligence), and dagger of clumsiness (less dexterity). Ego weapons with a monster friend type are also cursed items.
