Time for Poison with Plague Scarab in Soulkeep

I want to rent a new card that has a different abilities to be able to face fiends and get rid of them in that level that I am in so I went to the market and chose a good card that I have not used before and it is Plague Scarab which is a strong tower and can clear a wave of fiends with some hits,

Its attack type is area and this is what took my attention and this is a great ability if you use it well as you can slow down enemy even with slime lord or with a spell and make them burn with this tower poison as it has a blast range of 95 and fire interval of 4 is slow so I said using slowing tower or spell to be able to defend your gate.

Its poison damage is 82 and its duration is up to 7 and this is what I am seeking for a good ability and a better attack that lasts for a good duration also and also it can be used two times and this is also good if you use some tactics, when you use two tower with a distance between them about 2 seconds this will make you decrease the duration to 2 seconds.

Using a tower is not the aim only there is many things you can do to make this tower efficiency from 0% to 100% as its position increase its efficiency and also the spell you use with it like Gear Grease and also the time you use tower and against a specific wave and last thing the towers that close to it, as when you use a slime lord for example near a tower it increase its efficiency as it slow down fiends that pass near it.
