Overall Rating: Green. This means that
Soul Cage is a good spell.
Overall Notes: The best option here is definitely healing 2d8 as a bonus action 6 times, but the other options can be useful (depending on whose soul you suck up).
Class Specific Ratings for Soul Cage
Warlock: As you can only cast this 6th-level spell slot once per long rest, this burns your 6th-level slot but lasts for the entire day. The best option here is definitely healing 2d8 as a bonus action 6 times, but the other options can be useful (depending on whose soul you suck up).
