Summoner

 A character with this feat has grown incredibly adept at summoning powerful entities from beyond their plane to do their bidding, and enhancing the potency of such creatures in their employ. Any creature summoned by a character with this feat gains the following benefits:

• +2 to the creature's Natural Armor Class.
• Creatures summoned gain a +2 bonus to hit rolls, damage rolls, and saving throw DCs of actions they use, and their attacks count as magical if they did not already.
• All hit die the creature possesses are treated as their maximum results for the sake of determining the creature's hit points, and the creature receives 5 bonus temporary hit points per level of spell used to summon it. These temporary hit points last a number of hours equal to the level of spell used to summon the creature.
• If a spell would summon a random number of creatures, roll the number of summoned creatures twice and take the higher result.
