Subschool of Summoning

Your specialty is summoning, a subschool of conjuration.  You are excellent at calling creatures from other planes and places to fight for you and defend you.  As you gain more power and knowledge, you are able to enhance these creatures beyond what they are normally capable of, and use them to protect yourself well in combat.

Learned Summoner

Beginning at 2nd level, you have studied all you can about the subschool of summoning.  All conjuration spells that summon one or more creatures are added to your wizard spell list and can be scribed into your spellbook.

Durable Summons

Beginning when you select this subschool at 2nd level, anytime you cast a spell that summons creatures, they appear with additional maximum hit points equal to twice your level.

Powerful Summons

Starting at 6th level, you've learned how to augment the combat abilities of creatures you summon.  When you cast a summoning spell you can choose to give the creatures summoned either a bonus to hit rolls or to damage rolls equal to your intelligence modifier.  If the spell summons multiple creatures the same bonus applies to all of them.

Soul Link

Beginning at 10th level, you form a link between yourself and your summons.  While you maintain concentration on a summon spell, you have resistance to all damage types other than psychic.  However, when you take damage from any source you are resistant to, a creature from the spell you are concentrating on takes an equal amount of damage.

Dual Concentration

Starting at 14th level, because concentrating on summoning spells is as easy as breathing for you now, you can maintain concentration on another spell while concentrating on a summoning spell.  If you are concentrating on a summoning spell and cast another concentration spell, you can maintain concentration on both.  Likewise, if you are concentrating on any spell and cast a concentration summoning spell, you can maintain concentration on both.  You can also concentrate on two summoning spells at once.  If you were to cast a third concentration spell while maintaining concentration on two spells already, you get to choose which of those two spells you stop concentrating on, however one or both of the new spells you are concentrating on must be a summoning spell.
