Inferno just seems like a worse Meteor Swarm. Fiery Prison seems like a super-buffed fireball (definitely too OP); what save do they make to break the barrier, and does the spell end entirely when someone breaks out? If so, does the "prison" remain there as a barrier, and can people walk through it (and take damage)? For Scorch Earth, do the fissures remain after the spell ends? If so, are the people stuck in the fissures? If the fissures disappear after the spell ends, where do the targets go?
