OCP and Kachua
Kachua
The active official Kachua's Secret Box NPC is at sec_in02 126,178. It consumes K_Secret_Key and opens Main_Lucky_Box, with single/ten-opening options and inventory checks.
The custom Rotation 2 staging ZIP is not evidence of the live rotation. Its activation/probabilities have not been certified by this wiki import. Existing Kachua configuration was not changed.
Overseas Care Package
Custom OCP work exists in development, but the exported live import/loader snapshot does not establish that its staged custom reward system is active. Check the live beta announcements; do not buy/expect a specific rotation from a development handoff. Current item definitions are available for reference and beta @item testing.
