You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can't discern color in darkness, only shades of gray.

When you damage a creature with an attack or a spell and the creature's size is larger than yours, you can cause the attack or spell to deal extra damage to the creature. The extra damage equals your level. Once you use this trait, you can't use it again until you finish a short or long rest.

You can take the Disengage or Hide action as a bonus action on each of your turns.

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

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.

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.

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.

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