I am wondering if this interpretation of the interaction between the Pact of the Chain feature and Flock of Familiars is correct.
Pact of the Chain (emphasis mine) states:
You learn the Find Familiar spell and can cast it as a ritual. The spell doesn’t count against your number of Spells known.
When you cast the spell, you can choose one of the normal forms for your familiar or one of the following Special forms: Imp, Pseudodragon, Quasit, or Sprite.
Additionally, when you take the Attack action, you can forgo one of your own attacks to allow your familiar to make one Attack of its own with its Reaction.
Flock of Familiars (again, emphasis mine) states:
You temporarily summon three familiars – spirits that take animal forms of your choice. Each familiar uses the same rules and options for a familiar conjured by the Find Familiar spell. All the familiars conjured by this spell must be the same type of creature (celestials, fey, or fiends; your choice). If you already have a familiar conjured by the Find Familiar spell or similar means, then one fewer familiars are conjured by this spell.
To put it more precisely:
Does this mean that you can summon additional (although temporary) Imps/Sprites/etc?
Note: This is not a balance question, this is RAW only please.
Best Answer
The Imp, Pseudodragon, Quasit, or Sprite are conjured by the Find Familiar spell.
The Pact of the Chain feature says:
Obviously, it is the casting of find familiar that conjures one of these special forms.
So a Pact of the Chain warlock casts flock of familiars, which states:
Imp, Pseudodragon, Quasit, and Sprite are "options for a familiar conjured by the Find Familiar spell", since the caster has Pact of the Chain.
So we conclude:
A Pact of the Chain warlock can use one of these special options for flock of familiars.
