School of Abjuration

The School of Abjuration emphasizes magic that blocks, banishes, or protects. Detractors of this school say that its tradition is about denial, negation rather than positive assertion. You understand, however, that ending harmful effects, protecting the weak, and banishing evil influences is anything but a philosophical void. It is a proud and respected vocation. Called abjurers, members of this school are sought when baleful spirits require exorcism, when important locations must be guarded against magical spying, and when portals to other planes of existence must be closed.

Features

Abjuration Savant

Beginning when you select this school at 2nd level, the gold and time you must spend to copy an abjuration spell into your spellbook is halved.  

Arcane Ward

Starting at 2nd level, you can weave magic around yourself for protection. When you cast an abjuration spell of 1st level or higher, you can simultaneously use a strand of the spell's magic to create a magical ward on yourself that lasts until you finish a long rest. The ward has a hit point maximum equal to twice your wizard level + your Intelligence modifier. Whenever you take damage, the ward takes the damage instead. If this damage reduces the ward to 0 hit points, you take any remaining damage.   While the ward has 0 hit points, it can't absorb damage, but its magic remains. Whenever you cast an abjuration spell of 1st level or higher, the ward regains a number of hit points equal to twice the level of the spell.   Once you create the ward, you can't create it again until you finish a long rest.  

Projected Ward

Starting at 6th level, when a creature that you can see within 30 feet of you takes damage, you can use your reaction to cause your Arcane Ward to absorb that damage. If this damage reduces the ward to 0 hit points, the warded creature takes any remaining damage.  

Improved Abjuration

Beginning at 10th level, when you cast an abjuration spell that requires you to make an ability check as a part of casting that spell (as in counterspell and dispel magic), you add your proficiency bonus to that ability check.  

Spell Resistance

Starting at 14th level, you have advantage on saving throws against spells.   Furthermore, you have resistance against the damage of spells.
