Frog Boiler is one of spells that are for heavy fiends and this is like Anvil of Awe so you have to use it well when you need it in a battle there are epic or legendary fiends or whatever that has a HP above that of level of Frog Boiler that you would use.
Frog Boiler has a minimum HP of fiend to be triggered is 1111 and this is good as if you are waiting fiend that is heavy even at the end of the level or wave it will be waited and not activated until this fiend pass so as I have said it is for heavy fiends and hard times.
It can be used 3 times in the battle and with a radius of 100 and duration of 8 which means it will last for less than the half of the level and with damage multiplier of 1.1 and a physical damage that is good also could reach 500 or 800.
For level 10 you could see that its damage may be above 249k and this is amazing but remember that HP of fiend to trigger this damage will be up to 43k and it can be used then 12 times with radius up to 150.
