Description

An IPC "Senior Staff" work permit. Can be used for the Ascension of Physical characters.

Lore

In the IPC, only project team leaders will have a work permit in this style. For workaholics like these experienced staff, they'd sooner forget to wear clothes than this name card. "This is more than just a pass into Pier Point. It is a status symbol!"

Farm it smart

A BOSS material. The biggest pain: weekly bosses cap rewards per week, so this is often the BOTTLENECK that traps a character at the 70→80 ascension. Only fight the boss dropping mats for the character you are ACTUALLY building — do not spread thin.
