Dexterity

From Wormhole Sci-Fi MUD Homepage

Dexterity is a player attribute, influencing your chance of success with a number of skills such as sneaking, hiding and dodging.

Dexterity also affects number of items that a player can hold, although gaining levels affects this as well. If you find you can't hold as many items as you want to, you'll need to increase your DEX, gain some levels, or obtain a bag.
