Armor and Weapons are some of the equipment you can use.
Armor comes in three forms:
- Arcane (protects against magic damage, not very good against physical damage)
- Light (half and half)
- Heavy (protects against physical damage, not very good against magic damage)
There are a wide variety of weapons, you will probably alternate between two or three types over your career.
Since each type of armor and weapon has different requirements, see the class guides to see which to use: Archer, Assassin, Barbarian, Blademaster, Duskblade, Cleric, Mystic, Psychic, Seeker, Stormbringer, Venomancer, Wizard
