One of restricted gameplay variants that involves playing the game:
1. without equipment(usually inventory use is allowed). With magic users the variant is called "naked mage" which is actually much easier to play than physically-oriented classes.
Game which requires a mandatory weapon to use skills: this variant is transformed to "plain item run" using the lowest-tier items available to the player.

2.Without repairing items: letting items lose charges/durability.

3.No magic items run: restricted to normal/plain items.

4.Cursed Items run:items with negative modifiers(for games without such mods, items with non-class bonuses such as fighter modifiers for mage).

5.Living off the land: items must be found from loot. No economy participation.
