While official documentation keeps the exact timeframe vague, it typically follows standard industry practices for extended inactivity, such as a multi-week hiatus.### Is This Event Worth Your Time?For those who prefer a free-to-play approach or spend modestly, every bit of Oroberyl is precious. Because this initiative requires no grinding, it is a risk-free strategy to build up your currency stash for upcoming character banners. Even if you aren’t a social media influencer, reaching out to friends or participating in fan forums can pay off. Furthermore, returning players benefit by receiving a nice currency bonus upon linking a code, creating a win-win scenario.### Maximize Your Gains* **Reach Out Directly:** If you have friends returning to the game, coordinate with them to ensure they use your specific code.* **Leverage Communities:** Post your code in official Discord servers, subreddits, or guild chats where players are actively searching for connections.* **Act Quickly:** Since returning players can only use one code, reach out as soon as possible to ensure you are the one they link to.* **Don’t Forget Your Own Bonus:** If you are the one returning, remember that you can claim a bonus for using someone else’s code.### Closing Thoughts”Protocol Invitation: The Return” is a straightforward and rewarding way to farm Oroberyl, the most critical asset in Arknights Endfield. Given the lack of requirements, it is a no-brainer for any player looking to bolster their future summon plans. Secure your unique code and start sharing it before the “Homecoming” cycle concludes.
