What would be the most powerful Curse? I think it would be Reducto. Not including unforgivables and Transmogrification Torture.


Reducto's definitely one of the more powerful spells, but I'm leaning towards Fiendfyre considering it can destroy even horcruxes. That said, its status as a curse could be argued since it appears to be aimed in general directions, not applied on specific targets.

It'd be interesting to see someone who can actually properly control Fiendfyre (Crabbe wasn't skilled enough) to use it properly.
