Upgrade

Overall logic of upgrades:

1. When the pet reaches the maximum level, it needs to be merged in order to continue upgrading.

2. When the pet reaches certain level, it needs to rise rank to continue upgrading.

3. When the pet reaches S-⭐️⭐️⭐️⭐️⭐️, it needs breakthroughs to continue upgrading.

📈 Level:

The level up feature will be unlocked after passing storyline level 40. After leveling up, the pet's attack power and HP will be increased, and more powerful skills will be unlocked.

When the pet reaches the level, it needs to be merged to improve its star rating in order to continue upgrading.
