How to defeat Cookie?

Build in the video(Blackrock Week) – Rend Blackhand, Blackrock Pyromancer, Defias Bandits, Whelp Eggs, Blizzard, Dark Iron Miner, Harpies

Tips for the boss fight of Cookie :

1. Just attack the middle lane and grab the two treasure chests at the start.
2. Use Blizzard and Whelp Eggs/S.A.F.E. Pilot to clear the first wave of enemies on the left.
3. There’s a mining point at the bottom right of the map. Send a Dark Iron Miner to mine there.
4. After taking over the middle path, there’s another mining point. Send a small miner to dig there, but remember not to place it too far to the left, or it will be shot by the tower on the left path.
5. Continue to send troops from the middle path. Remember to head right to fight the boss. At this time, the second wave of group enemies refreshes in the upper right. Use Blizzard to deal with them.
6. A big group of enemies refreshes on the left-top. Since our main attack is on the right side where the Boss is, we won’t encounter them. Wait until you have Blizzard and then use Whelp Eggs/S.A.F.E. Pilot to clear them.
