OK, I have NO IDEA who to listen to. I found this great orange leather armor that adds intelligence, but its a leather armor, NOT a robe... It seems to be affect my movement speed or am I just paranoid?
In this game the robes, cloth armor, and leather armor provide movement
bonuses, while mail and plate armor give movement
penalties. These movement bonuses are typically the same across all three of the above armor types, with larger bonuses being granted as the item level increases.
Mail and plate armor can give minor movement bonuses as well, but only when magically augmented. You'll know when that's the case by looking at the movement text in the item stats - it'll be blue (when enhanced) instead of white.
Likewise, the movement bonuses on robes, cloth armor, and leather armor can be enhanced beyond their default values as well. As above, the movement stat in the item details will be blue (when enhanced) instead of white.
Cloth and leather armor also provide a standard initiative bonus. Robes, mail, and plate armor do not (although it can come randomly as a magical enhancement).
