Can Shock Therapy Stop Fiends?

Shock Therapy which I have got from the market is so amazing in dealing with fiends and imagine that Cauldron Dweller is being eliminated with it with just one or two hits as its physical damage is up to 1000 making Shock Therapy is so powerful one that made me pass 5 waves easily.

When you put it in a way it is completely closed and if some fiends escape I have prepared card sharp and also stew of doom to be able to deal with them as they passing from Shock Therapy with very low health and all they need is a smash from stew of doom or a hit by card sharp.

It is chain hit is amazing in facing Cauldron Dweller the most dangerous one in that level and I have put shock therapy on Cauldron Dweller way but in final waves they are coming from another way so I have lost some hearts as card sharp was not able to attack them all but I have found a very good card.

What I will do in the next playing that I will use Shock Therapy and also will upgrade it so it will be more dangerous that with one hit eliminate and get rid of Cauldron Dweller and any fiend in the way and also I will use Gear Grease so it will be faster and dangerous and this will be like a nuclear weapon in the battle.

Shock Therapy can be used with 180 Mana but with Cheapo you can add it with 120 Mana and this is very good comparing to its features and its chain attack type, So let me try another time and I feel that this level is about to be passed and then I am going to other league with new features to be unlocked.
