Every time you rescue, there is a chance at getting an item or a pair. Additionally, it lowers the cooldown for watering and fusing.
Suppose the following:
| Go to sleep | Rescue cooldown finishes | Wake up | |
|---|---|---|---|
| Time | 00:00 | 01:00 | 07:00 |
If you don’t do anything, you’ll rescue once at 07:00. That is 1 roll only, and you will end up with 1 animal.
If you release an animal, you can rescue right away. Then at 07:00, you can rescue again. That is 2 rolls, and you will still end up with 1 animal. However, that additional roll gives you a chance at getting an item or a pair, and also lowering your cooldown for watering and fusing.
