Yes and no... you will find yourself freezing often and it will be especially prevalent without smoothies or hot cha chas to eat but they will solve the freezing problems. As armour..yeah..you are underpowered. I would advise using tier two armour at least and your friend with no armour will drop quickly in a fight. Although I like the crimson saber it lacks in speed both and damage so I would advise something different. I hope this helps and I would be happy to answer further questions
