I have talked to the reps of each PG with a Headquarters, and the following have been approved for Monthly Perk Bonuses.

Ixian Knights

The IK will receive a 20% increase to either GP or Exp per member for threads completed in Corone. This is up to each individual member which option they wish to take. This will last so long as the IK has their HQ.

The Tarot Hierarchy

The Hierarchy will receive a monthly magical item to be approved by the features staff. This will last so long as the Hierarchy maintains a HQ.

The Trading Company

The Trading Company has opted for materials as their perk, as such The Trading Company will receive 3 copper ores, 3 stacks of leather, and 3 logs of oak wood every month so long as they maintain a HQ.

Misery Business Incorporated

Misery Business chooses to embrace the battle nature of the Three Stock Pagoda and has wished to receive a 50% increase to GP for every battle completed until they no longer hold a HQ.

This is a compilation of perks given to the current HQ owners, and more will be provided as HQs are taken over and/or lost. Thank you.
