Weapon and Armor Proficiency: Grand summoners are proficient with light armour. A grand summoner can cast spells for one base class of her choice while wearing light armour without incurring the normal arcane spell failure chance. Like any other arcane spellcaster, a grand summoner wearing medium or heavy armour, or using a shield, incurs a chance of arcane spell failure if the spell in question has a somatic component. A grand summoner still incurs the normal arcane spell failure chance for arcane spells granted by classes other than the base class she selected.

Spells Per Day/Spells Known: When a new grand summoner level is gained, the character gains new spells per day as if she had also gained a level in the spellcasting class she belonged to before adding the prestige class. She does not, however, gain other benefits a character of that class would have gained, except for additional spells per day, spells known (if she is a spontaneous spellcaster), and an increased effective level of spellcasting. If a character had more than one spellcasting class before becoming a grand summoner, she must decide which class gains the ability to cast spells while wearing light armour and adds the new levels for purposes of determining spells per day. Once this choice is made, it cannot be changed.

Summoning Ceremony: Once per day, the grand summoner may summon any creature available to her via spells of the conjuration (summoning) subschool. This creature remains out for the grand summoner to command for the remainder of the day, or until the summoner next rests or falls unconscious. The ceremony takes ten minutes and requires unbroken concentration.

Exchange: A number of times per day equal to the grand summoner's intelligence modifier, she may replace any of her summoned creatures with another that she is capable of summoning with an equal or lesser level spell. If this is a creature summoned via a spell and not the Summoning Ceremony, it inherits the remaining duration from the previous summon. Additionally, the new summoned creature will retain any damage that the previous summoned creature had taken.

Improved Summon: At 2nd level, the grand summoner gains the ability to modify creatures summoned with the Summoning Ceremony. Upon summoning, the summoned creature may select 4 points worth of evolutions available to a summoner's eidolon. Every two levels thereafter, this number of points increases by 4, to a maximum of 16 points at 8th level.
