Suggestion for a new bomb

I was thinking about a new bomb (suggestion name is earth storm) with a large range and NO status effect. The bomb should deal only elemental or elemental and normal damage and when used cause an easth shockwave on the ground (it must look cool ofcourse too). This bomb's wave is simular to thos of the status effect boms like shilvermist buster, ash of agni, venom veiler etc. , but with a brouwn quake in a wave like water, but then no water but ground. Or this bomb shoul have a own alchemy path or we just make the bomb a ne invention on another's bomb alchemy path (suggestion it would be on the haze bomb's alchemy path). it would'nt realy look the same form as the elemental bombs. I would say somthing dark brouwn, and round with thick spikes.
You see what u do with this tip!
