I have like 347 power, 34 skill, and 1 corruption
You got to train every chance you can get and get the horn, the crab pincher, the monster spine, go directly to the west in your nyx mission and she'll give you a serum, fight in close combat against Lauren, and choose the why not I can take it option when going against the one girl with light powers. Also, go to the gym and gymnastics it'll give you skill and some power and remember to wear your helmet. When fighting against Valravn choose in order keep your distance, go all out, and I don't need to evolve. In the hero base you also have to train against Alice and Michael
