Very familiar with abjuration magic in particular, you gain the following benefits.

• The gold and time you must spend to scribe a spell scroll of an abjuration spell, as well as to copy an enchantment spell into your spellbook, ritual book, or Book of Shadows, is halved if it isn't already.
• You have advantage on saving throws against abjuration spells and against spells cast through a glyph of warding, as well as on Intelligence (arcana) checks made to recognize an abjuration spell or its effect.
• When you cast an abjuration spell, such as dispel magic or counterspell, which requires you to make an ability check with your spellcasting ability, you can choose to make that ability check with advantage. Once you use this feature, you must finish a short or long rest before you can use it again.
