Death splinter quest done in six matches. During it I was able to reach the Diamond I league.
It was fairly easy. Luckily, most of the matches were with high mana which helped a lot.
Rewards
Let's buy the Quest potion and open the chests, 19 of them.
Nine cards, two of them rare. Quite decent loot.
Upgrades
Ant Miners to level 2
I don't see any use for these guys. Maybe in low mana reverse speed matches with Fire. Not many chances for that.
That was it.
End of the season approaches
One day and ten hours to go. Fire splinter is the next quest. Can I reach Champion league?
Better and better
