Trying Knife Trosser and Slime Lord in Soulkeep

In this battle I have to try new towers to gain more experience about this game and which tower is powerful against fiends and what it will be when upgraded this is what I need to know in this wave as fiends is coming I will put these new towers.

The towers that I have chosen are 3 and one of them is so regular and it is Gloom Owl as this is the first choice and can not be replaced whatever you have others but it proved that it is a good tower against fiends with low health and also fast ones and the other two are Knife Trosser and Slime Lord which I want to try.

This battle is not so hard but fiends that came in high waves is so dangerous and these what made the difference from this level than the level 1 as there is blood queen which gives more bloodlings that are so fast and cause me losing many hearts if they are close to the gate.

I have passed two waves with three towers which are the towers that I started with but I have discovered two things that Slime Lord is not so effective against fast fiends as it has high fire interval so I need to replace it with other tower.

From the wave 3 because of Slime Lord I was playing with only 1 heart but I have succeeded to pass 3 waves while discovering the second thing that was upgraded tower better than one tower from the same type as I used my mana to upgrade Gloom Owl and King Trosser and this make me passed three waves without losing a heart.

At final wave there was a new fiend detected that I do not count for it and it was slaying mantis which was so strong with these tower and with the low power of Slime so I now get the basics for this level.
