Stamina ​

When your tamer goes out to collect the MUT from the mining site, he/she expends stamina because of all the energy required. Similarly, stealing also consumes stamina of your tamer.

For every collect action you perform, 10 Stamina is deducted from your tamer. Similarly, for every steal action you perform, 10 Stamina is deducted from your tamer.
