An item's Base Type refers to the specific variety of item it is, and grants it inherent properties such as damage on Martial Weapons, defensive bonuses on Armour, or Life recovery on Life Flasks. It is also often responsible for the Level and/or Attribute Requirements to equip an item.

For example:
• Wrapped Quarterstaff and Long Quarterstaff are both Quarterstaff Base Types
• Stocky Mitts and Linen Wraps are both Gloves Base Types
• Lesser Mana Flask and Greater Mana Flask are both Mana Flask Base Types
