Yes, it's L2J—specifically L2Lucera—but it can be adapted for L2jAcis and Lucera; I imagine it would work for High Five as well. For now, I've only implemented it in L2Lucera (Interlude), but it will be available for L2jAcis too.

As soon as you log in with your character, the window opens automatically so you can collect your reward. You can change the daily item ID and icon, and even set a waiting period—like 30 minutes—before collection is allowed. It includes IP protection, so players can't claim rewards using other accounts or create new ones to exploit the system; you can also adjust the number of days (e.g., 28, 1, or however many you prefer), and every feature can be enabled or disabled.
The player command is `.daily`, and there are also four GM commands.
I’ll be uploading a short video tomorrow to show everything more clearly. I also plan to improve the HTML window design and add MAC and HWID systems to prevent users from bypassing IP restrictions via VPNs or abusing the system with multi-accounting—basically, I’ll be continuously refining the system.
