Is the Protocol Pass worth buying in Arknights: Endfield?

The Originium Supply track is highly recommended even for F2P players because it refunds the full Origeometry cost upon completion. The Protocol Customized track is only worth it for cosmetic collectors.

How do I earn Pass EXP in Arknights: Endfield?

You earn Pass EXP by completing 100 Daily Activity Points (2,000 EXP), weekly missions (larger EXP rewards), and using Vacation Tags to double your Pass EXP on catch-up days.

What are Vacation Tags in the Protocol Pass?

Vacation Tags are a catch-up mechanic. If you miss reaching 100 Activity Points one day, a tag activates (max 3). When you next reach 100 points, an activated tag doubles the Pass EXP earned.
