[MENTION=59848]Hawk Diesel[/MENTION] you're right, I completely misread Bestow Curse. That makes Bestow Curse fairly weak for a 3rd level spell, IMHO. I'm not sure I agree that my changes would make RoE better than Heat Metal. While Heat Metal has the limitation of someone wearing metal armor (or holding a metal weapon), at the cost of a bonus action, the caster can do 2d8 fire damage every round and cause disadvantage on attacks and all ability checks. That's a bit better, imho. Like I said, I just don't rate a bonus/penalty to ability checks that high compared to other types of rolls made in combat.
