Guardians make their fighting partner stronger, increasing their damage and defensive rating, which are key buffs needed to overcome the forces of Gargos.
In this video we look at the Snake’s Poison Bite which applies Potential Damage to your opponent.
Of course, there are other Guardians to use besides this one, and plenty of other techniques. Don’t be afraid to experiment with the Guardians and figure out which works best with your play-style. Last but not least, drop by the Shadow Lords section of the forums should you have any questions about Guardians or their uses.
