Burning Soul Instinct
Level 10 Effect When in Defense Mode, raise the Damage and Evasion of Units behind Self. When not in Defense Mode, raise Damage and Evasion of Friendly Melee units in a radius of 3. Firepower is increased by 15% and evasion is increased by 40%, with a max of 3 stacks per unit.


The laughingstock of SF units since the start of the game, Prowlers are not saved by Protocol Assimilation. Classed as a Melee unit with limited Evasion and HP, and a support Skill, Prowlers are more than likely going to do nothing but increase your repair bills.

Yet another multi-function Skill, the Prowler can either buff the units positioned in the rows behind. These buffs are relatively potent, up to 36% Damage and 90% Evasion when at max stack. However, the positional requirement limits their value, and leaves Prowlers as an easy scrap once again.

Skill Priority

Burning Soul Instinct
Low Priority Skill levels do not improve the performance of Prowlers enough to make them worthwhile, and they have enough other flaws as units that the cost of leveling their Skills is difficult to justify.
