Would be a bomb that creates a pulse wave similar to the Tortodrone Stun ground slam. The pulse would go out (doing knockback Comparable to the DBB)(and creating a very short "haze" effect similar to StaggerStorm) and after it fades 8 spikes (6 spikes for 3 and 4 star) pop out of the ground randomly within the bomb radius (think jelly cube spikes), these spikes would hinder movement and do damage like the Tortodrone gun spikes. These Spikes would take the same amount of time to fade as the Tortodrone gun spikes

There would (of course) be 4 versions for each damage type. Each of these bombs would be crafted up from their respective shard bomb (a reason to actually craft/buy one).
