Topic: Monsters' Den Chronicles / Team for Duo and Trio Achievements
I just got the Duo badge by using the shield Warrior and the Ranger Warden for healing. It helped that I happened to find a Dawnslice sword and the Spark of Legend to level it really quickly. The sword gives huge bonuses to Intellect, healing skills, being healed, and a 75% chance to remove one condition on healing. Going try the Trio pretty soon.
