There are supernatural phenomena in the Index world which are sufficiently large/powerful enough that they surpass the negation speed of Imagine Breaker and apply a physical force onto it. These include but are not limited to:
 * Index's Dragon Breath and various other grimoire spells of hers.
 * Accelerator's Wings
 * Fiamma of the Right's Holy Right

Misaka's death ball falls into the same category. Sticking Imagine Breaker into the death ball was not the best way tackling it.
