The first quest was using LIFE summoner to win 5 ranked battles.
On the first quest, I got Goblin mech.
Its mana is 10, so I couldn't use this in most of battles. But I like it :)
It didn't spend much time to unlock Bronze league III.
Before I start to ranked battle, I practiced a lot :)
So, I recommend for beginners like me to use practice battles.
It will help you how to manage your team.
Have a good day. I'll come back soon with the post about Quest DAY 2.
