Gloom Owl and Charnel Pit for Defense

I have used many towers as first line of defense as a first tower to be used and this is like Gloom Owl and other towers also I have used it in the first position close to the opening of those where fiends came from and this is was very cool.

Gloom Owl is chosen to be the tower of defense and adding this one to be first tower to face fiends is a risk but I have to take this risk and to try hard to see what I can do with this tower and what if I upgraded it.

I have used Gloom Owl and then charnel pit and this is because charnel pit proven its ability to be a second tower of defense in attacking fiends and to have such a good ability for killing fiends that have low HP and low health after GLoom Owl attack.

Having Tower after tower would eliminate the remaining fiends that would come from the battle and pass to have your hearts being lost so you have to consider that in your plan and you have to consider to be a good soulkeeper just with any plan available.
