Today I have reached the most wanted cave: Diamond Vault XV. But now I´m so angry because I failed 3 times!!! Can someone help me with this? Don´t tell me to use scrolls because I´m a free player .
My stats and my combo:
Spells: Blizzard level 10, Shield level 8, Sonic Blast level 6 (I´m upgrading to level 7)
Troops: Cannons level 6, Frosters level 7
