Having an air and land attack is difficult, especially if you need to do it for the event challenges and do not have a strong land attack.
I main air attacks in COC, my favorite is the electro dragon at this current level. 2 things made this attack easy 3 stars.
- Inferno towers set to multi target
- Xbows on the sides set to land target only.
The xbows set to land only allowed me to clean up the sides and funnel my troops into the center. With the ghosts I then cleaned up the top section that had all those archer towers which do damage over time against electro dragons as they attack slow.
