"Adventurers such as yourself oft stand upon the front lines of battle. Owing to this, you are like to find yourself in many situations wherein a capacity for healing would be advantageous. Mind you, there is more to conjury than that.
By harnessing the power of earth, wind, and water, conjurers are also capable of weaving spells that wreak havoc.
In terms of sheer destructive power, conjury may pale in comparison to thaumaturgy, but its capacity to defend one against aggression more than compensates for this relative shortcoming.
More than simple healers, yet not true dealers of destruction, conjurers realize their full potential when they employ their powers in support of others. This, my dear adventurer, is what it means to be one of us."
