Energy, cooldowns and streaks
How often you can fish and how to keep the pace up.
Spending energy
Every cast costs energy. The base maximum is a flat 100. It does NOT grow with player level. The only way to raise your cap is the Museum Shop's Ancient Energy Reserve buff (+10 max energy per purchase, up to 20 times for +200 total). Energy regenerates passively at 1 point per minute whether or not you're online.
Refills
There's no refill item that drops from chests or quests. Instead, /energy refill tops your bar all the way to full instantly for a flat 25 gems. Useful when you want to keep casting into a good weather window without waiting out the regen timer. /energy on its own just shows your current energy and cap.
Streaks
Claiming /daily builds a streak that makes the reward grow over time. You have a 48-hour grace window to claim again and keep the streak alive. Wait longer than that and it resets to zero.
