Crystal weapon themed build.
Other notes:
I didn't want to use the armour as I wanted it to look a bit more blue for the crystals.
I also didn't want to use the crystal shield as it can't be repaired and it isn't farmable.
You can also use a crystal infused buckler instead of the heater shield.
If you have a lighter equip load you can also use the wolf ring or leo ring instead of havels or ring of favor, if you don't care about fast rolling use heavier armour.
