@Wizards_DnD @mikemearlsI noticed most spellcasting NPCs follow the multiclass spell slots(PHB) but not all.Is that on purpose or in error? For example:Mummy Lord(10th-lvl) uses the slots for 11th-lvl. Acolyte(1st-lvl) uses 3 1st-level slots, not 2.

@PeanutButterDM @Wizards_DnD we generally follow progressions, but sometimes swap them up to fit monster design as needed.
