The Lore-master's Staff Legacy Staff Strike Damage increases the damage of this skill.
Staff-strike is one of the few damaging skills that doesn't have an induction. The damage type it deals is dependent on the damage type of your staff. On a side note: fighting in melee range greatly increases the DPS of any player because of auto-attacks taking place. This is also advisable for Lore-masters, as long as the goal is to take the enemy down as soon as possible and the Lore-master doesn't take too much damage.
