Spellcasting is a key part of the Warlock class and it plays a big role in their abilities. Warlocks have a total of eight spell slots which they can use to cast their spells. Each spell slot can be used to cast one spell of the warlock’s chosen school. So a warlock with eight spell slots could cast eight different spells using those slots.
Warlocks also have the ability to convert their remaining spell slots into Wild Magic Points, which can then be used to cast any spell in their spellbook. So a warlock with four spell slots and two Wild Magic Points could cast any of the spells in their spellbook, including ones they haven’t learned yet.
