Some Tricks for Level 4 in Soulkeep

Shrimpify is a spell of choice to make fiends weaker and smaller to eliminate them one by one and to pass more waves as I am in Sharp Defense Map in Level 4 as this level is a little different from other levels as from wave 2 there are high number of fiends that came from two ways and this what make building a good defense is a little hard so Shrimpify is a good option to weaken fiends in that level.

In this level also there are so different types of fiends that came together and this means that you should have different types of towers also to be able to withstand against first two waves and as you have 12 Hearts you should save them to be with you for 6 waves in a row.

Tricks that may be useful in this level to help you and save you some towers in every wave as there are two gates and there are two ways for them and they are parallel to each others so if you put towers between them with good range they will cover the area in attack fiends that come from both ways and this will save you some mana and upgrading these towers will be a good option to be able to attack both sides.

Other Trick that there are in this map a short way with an opening that fiends came from and this connects to a way that are going to the gate and there are two angle for those ways so you can put towers there and this will cover a good area also and act like a double defense.

This is What Shrimpify can do and you can use stew of doom with it this will help in destroying as much as fiends they could:
Minimum HP of Fiend to Trigger Spell: 500
Uses: 3
Spell Radius: 80
