Charlga will Root all nearby enemy ground Troops, immobilizing them. Tending a Briarthorn garden is so much easier with geomancy.
Huntress or Harpies work well to defend against the 6 Quilboar spawns. Flying Minis can ignore the root mechanic of the boss so Quilboar can be used to distract with Whelp Eggs behind them. (Root damage will break Whelp Eggs).
For every PvE mission, there is a campaign version and a Heroic version. When you first begin the game, you can only participate in campaign missions. Upon collecting 50 sigils, you will then unlock Heroic missions.
Campaign missions will grant rewards after the first successful clear with ANY family. Heroic missions must be completed with EACH of the 5 different families in order to receive the mission rewards.
