Spells To Be Used For Fiends Attack
Spell to be used in Soulkeep may save you lots of mana and may help you using less towers than those who were used in a battle without these specific spells wo choosing the right spell and choosing how to deal with fiends that are coming in groups from the first wave till the last one.
From Spells that are good and can be used in any battle Venus Fiendtrap which I considered the best spells from common spells in the battle as it has a very high damage that could eliminate 5 Fiends whatever their HP is and then you could use it to defend the gate and to save your hearts and if you are facing even epic fiends in the last wave it could do a good job.
Other Towers that could be used with a spell as it could not be used alone and this spell is Gear Grease and its mission is to enhance the damage and the ability of the fiends and to have a good fire interval so we use it for towers that have fire interval above 4.
Raining Cats is acting like Venus Fiendtrap but it is less effective than it and so its use would be for only those weak fiends with low HP and those that are in a group so you could get the best from raining cards and in this case you could use it well.
Kansas Twist is one of Spells that make what is like a hurricane to stop fiends and slow them down so if you have a slow tower or strong one in this area so using kansas would be a good choice to eliminate these fiends and to have such ability to attack and defend the gate and save some of your hearts.
