- Go to Fire Field Farmers Town (Orc Town) and look for Oth.
He will tell you about orcish magic and ask you to get for him four orcish tribe spellbooks.
- Head west of town and hunt tribal orcs until you have Spellbooks of Gandi, Atuba, Duda-Mara, and Neruga.
- Bring these books to Oth and he will reward you with your choice of either
Helm of Dexterity (-1 AC Base, +1 DEX), or Helm of Constitution (-1 AC Base, +1 CON).
These helms are safely enchantable to +6.
