This Fractured But Whole class is definitely the most unusual class in the game. Using weather-based status effects, the Elementalist can easily deal with multiple enemies at the same time. Sand Trap and Ice Prison are some of its best abilities that not only delay enemy attacks but also do some well-rounded damage.
But nothing comes close to the Elementalists ultimate ability -- the Elemental Onslaught. This ultimate gathers the powers of all elements and hits the enemies with Shock and Chill effects.
If you're looking for the best support class in The Fractured But Whole, then make sure to pick up the Elementalist.
