I have some ideas form hulls and its overs First its "spikes", and like its name says, it will have spike, but only in its front, also its size will be like hunter and also its hp. And if you touch the spikes, you will get damage per second, not so big, but enough to be a threat, maybe will be 10/s. And its over will be that when you activated it, the hull will have spikes in all the sides and have a little boost of speed and a little protection from damage. And my last idea from a hull, "Arrow" and its shape is like an arrow in its front, also the size will be like viking and the hp like the dictator. And its over will be a big and fast boost that if it hits you, you will be stun for some seconds. the speed of both will be fast. (all values and names can be changed, I only puts those values from an example)
