At 5th level, the conjurer’s summoned creatures become particulary tough to dispel. Add 2 to the DC of any caster level check made to dispel the conjurer’s summoned creatures. At 15th level, this addition to the DC increases to 4.
At 10th level, the conjurer’s summoned creatures gain an additional +2 bonus to Strength and Constitution. At 20th level, the bonuses increase to +4. These bonuses stack with those granted by the Augment Summoning feat.
