Pact Magic Warlock spell slots (also known as "pact slots") are not like those of other spellcasters. Warlock spell slots are equal to the highest level of Spells the Warlock has access to.

Warlock spell slots Recharge: short rest (spell levels 1-5) Expended by warlocks to cast any spells they know. Warlock spell slots are all the same level, and any spells casted by expending them are upcast accordingly.
