I'll throw in my ranking for the top cursed techniques
1. Cursed Spirit Manipulation (I admit this feels like Pokemon with curses, but really like the possibilities with this one. Potentially the strongest technique I'd argue)
2. Limitless (An infinity barrier, shooting lasers, distorting space at will... nuff said)
3. Idle Transfiguration (another OP technique, the possibilities are almost endless, and most people are doomed after one touch)
4. Boogie Woogie (might also be because of Todo, but this technique is incredibly useful in a brawl. Love how it fucks with everyone's mind lol)
5. Ten Shadows Technique (relatively simple, but has a lot of variety. Can potentially be very OP, as seen with Mahoraga)
Special mentions to Cursed Speech and Projection Sorcery. Shouldn't forget Nobara's Resonance either. This manga really has a lot of very cool and fascinating techniques
How would you guys rank your top Cursed Techniques?
