Agony

Any suggestions for improvements are more than welcome.

I think you may want to increase the damage on this spell. The fireball spell, for example, does 8d6 damage and has are of effect damage, but is a lower level. I think you should either lower the spell level or increase the damage by a lot. Other than that, however, I really like your spell.

The damage was not increased because of the powerful debuff that tags on to it.  I usually use Fireball to scale my spells, and this one seemed to hold up alright.  Disadvantage on all attacks and saving throws is incredibly powerful, especially since they can't save each turn to end it.  Thanks for your feedback, though!

Here's the funny thing:

It's supposed to say "each slot level above 4th."  That was my bad.  My thoughts were, this debuff is basically a reverse slightly weaker version of foresight, with a saving throw.

Thanks for your feedback!

Thanks for the suggestions!  I'll definitely take them into account.

I find this to be a very interesting spell.  That said I would consider making it a constitution saving throw.  I say this because other pain based spells like both Symbol and Power Word Pain both use Con as their save of choice.  I understand the thought that the damage is psychic in nature and your willpower is enabling you to act through it for consistency across the system I would consider constitution.

I also agree that a slight damage bump may be in order say to like 6d8 plus 2d8 for each level over 4th.  

The proof though, as always, will be how it plays in your game and if you and the others enjoy it.  Hope the feedback helps.

Thank you for all the feedback, everyone.  I'm working on a new version of this that should be released shortly.
