Mastery of Conjuration & Summoning
Class proficiency — see Proficiencies for the rules and the Proficiency Index for the full list.
When the character casts summoning spells, the spell effects are calculated as if he were two caster levels higher than his actual level of experience. (This makes them harder to dispel.) If the character would lose his concentration due to taking damage while controlling a conjured creature, he must make a Spells saving throw. If the save succeeds, he maintains his concentration. His eligibility to conduct research on summoning magic is determined as if he were two caster levels higher than actual. He gains a +2 bonus on magic research throws and increases his research rate by 10% when researching summoning magic.
