The monster is considered a member of that class when attuning to or using a magic item that requires membership in the class or access to its spell list.\n\nA monster can cast a spell from its list at a higher level if it has the spell slot to do so. For example, a drow mage with the 3rd-level *lightning bolt* spell can cast it as a 5th-level spell by using one of its 5th-level greater or lesser threat than suggested by its challenge rating.\n\n### Psionics\n\nA monster that casts spells using only the power of its mind has the psionics tag added to its Spellcasting or Innate Spellcasting special trait. This tag carries no special rules of its own, but other parts of the game might refer to it. A monster that has this tag typically doesn't require any components to cast its spells.\n\n",

You can recover either a 2nd-level spell slot or two 1st-level spell slots.\n\n### Arcane Tradition\n\nWhen you reach 2nd level, you choose an arcane tradition, shaping your practice of magic through one of eight schools: Abjuration, Conjuration, Divination, Enchantment, Evocation, Illusion, Necromancy, or Transmutation, all detailed at the end of the class description.\n\nYour choice grants you features at 2nd level and again at 6th, 10th, and 14th level.\n\n### Ability Score Improvement\n\nWhen you reach 4th level, and again at 8th, 12th, 16th, and 19th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can't increase an ability score above 20 using this feature.\n\n### Spell Mastery\n\nAt 18th level, you have achieved such mastery over certain spells that you can cast them at will.
