The Grand Catch DLC introduces an automated fishing system to Spire Horizon Online. Fishing is a popular activity within the game, allowing players to gain experience and collect valuable items for crafting or trading. Normally, fishing requires players to manually cast and reel in their catches, but with The Grand Catch, players can automate the process. This feature lets the system handle fishing for you, giving players the freedom to relax, engage in other activities, or simply enjoy the game without needing to focus on fishing. It's a perfect solution for those who want to maximize their time and efficiency.
