When you cast the spell, you choose one of the normal forms for your familiar or one of the following special forms: [Imp](Mechanics/CLI/bestiary/fiend/imp-xmm.md), [Pseudodragon](Mechanics/CLI/bestiary/dragon/pseudodragon-xmm.md), [Quasit](Mechanics/CLI/bestiary/fiend/quasit-xmm.md), [Skeleton](Mechanics/CLI/bestiary/undead/skeleton-xmm.md), [Slaad Tadpole](Mechanics/CLI/bestiary/aberration/slaad-tadpole-xmm.md), [Sphinx of Wonder](Mechanics/CLI/bestiary/celestial/sphinx-of-wonder-xmm.md), [Sprite](Mechanics/CLI/bestiary/fey/sprite-xmm.md), or [Venomous Snake](Mechanics/CLI/bestiary/beast/venomous-snake-xmm.md) (see appendix B for the familiar's stat block). Additionally, when you take the [Attack](Mechanics/CLI/rules/actions.md#Attack) action, you can forgo one of your own attacks to allow your familiar to make one attack of its own with its [Reaction](Mechanics/CLI/rules/variant-rules/reaction-xphb.md).
