Towers in Soulkeep are the main weapons that you could use in the battle and when you choose the best towers so passing the level would be much easier and this is what we all want but remember there is not absolute powerful tower for all fiends as every tower has a great effect against some of fiends and less effect against others.
So your main task is to choose the good ones for the fiends that are in your level and also in your wave and in this case you would find that passing the level would be much easier and you would kill more fiends and also gain more mana Which making passing the remaining waves more efficient.
You can modify towers in soulkeep using spells which has also an attacking ability but most spells that are in the market or even with you in the deck would assist towers in their mission for attacking fiends and stopping them from reaching the gate and consume more hearts.
Gear Grease is one of those spells that assist towers and could make some modification in towers action and this by increasing its fire rate, As it could decrease fire interval of any tower by about 20% which making it faster and have better abilities.
Higher Ground is one of spells that are so useful and could change the direction of the battle by enhancing towers range so a tower with lower range could attack wider with Higher Ground and in this case you could benefit from its attack in a better way instead of attacking fiends for a short period of time.
