I have found that the zoni blaster helps some but I am unable to make it through entire area without getting damage,The cold hearted I am unsure what is going wrong I break all the breakable ice except the slide. Has anyone gotten these skill points?
You have to get through the entire level of the polar sea without dying at all, there are also icicles next to the final endpoint right after you fight the grungoths. You have to use a long range weapon to get them or you will trigger the cutscene. Hope this helps.
