Create Giant Insect

You perform an ancient rite of molt and metamorphosis over a living, Tiny, nonmagical insect you touch (your DM may allow a similar small arthropod, such as a spider). When the casting is complete, the target transforms into the giant version of that creature. For example, a beetle might become a giant fire beetle, a wasp might become a giant wasp, and a spider might become a giant spider. The transformed creature uses an appropriate stat block chosen by the DM. (Feel free to get creative with species and homebrew with you DM or players.)

The transformed creature is friendly to you and your companions. It rolls initiative and acts on your turn (immediately after you). It obeys your verbal commands (no action required). If you issue no command, it takes the Dodge action and uses its movement only to avoid danger.

The creature’s Intelligence increases by 3, and it understands the languages you speak, though it can’t speak.

Brood Capacity

You can control a limited number of giant insects created by this spell. Your brood capacity equals twice your proficiency bonus. Each giant insect created by this spell costs a number of brood points equal to the larger of 1 and twice its Challenge Rating (minimum 1). For example, a CR 1/2 creature costs 1 brood point, a CR 1 creature costs 2 brood points, a CR 2 creature costs 4 brood points, and a CR 3 creature costs 6 brood points.

If you cast this spell when doing so would cause you to exceed your brood capacity the spell either fails or you must choose one giant insect you currently control with this spell. That creature immediately reverts to its normal form (unharmed), and your bond with it ends. If you don’t have enough points spare, the spell fails.

Ending the Bond

A giant insect created by this spell remains transformed until it drops to 0 hit points or you end the bond as an action while within 5 feet of it, causing it to revert to its normal form, unharmed.
