I used to get a full stamina count upon level up. Now that I have a higher stamina (100+) I never get a full refill of stamina on level up, especially when attacking a boss or doing battles
There's a limit to how much Stamina you gain when you level up. The maximum is 50, however you can use Daily Rewards and Boosts from your Mob to top it off. Make sure to keep an eye on the in-game news feed for Bonus Boosts as well!
