Get Battle Axe and Armor:
     Talk  to  Brenna  outside  the castle with an extra space in your
party,  tell  her  it  is  too  dangerous. She'll then give you a free
Battle Axe and Idem Scale.

Free Inferno Flask:
     In  the  town  outside  Gwernia  castle,  there is a house with a
lean-to  on top. Go inside and you'll see a bag with an Inferno Flask,
give this to anyone with Alchemy.

Chaos Sword:
     Go  over  the bridge out of town and turn left onto the beach and
then  make a right at the shrubbery. Here you'll find a path. You will
find  a  campsite, and a short intermission for your journal. Inside a
chest here is the Chaos Sword. Remember you'll need 25 strength to use
this.
