You hurl an undulating, warbling mass of chaotic energy at one creature in range. Make a ranged spell attack against the target.[...] If you roll the same number on both d8s, the chaotic energy leaps from the target to a different creature of your choice within 30 feet of it. Make a new attack roll against the new target, and make a new damage roll, which could cause the chaotic energy to leap again.

Varje varelse som träffas av bulten anses vara ett nytt mål.

Stavningen säger dock i slutet:

A creature can be targeted only once by each casting of this spell.

Det betyder att en varelse som tidigare träffats (riktad) av samma gjutning av kaosbult inte kan väljas som ett mål igen.
