Anyone can do it. My Angel Bow is Electric +6 and its all static looking.
To do this to your weapon:
1.Grab some flame cards (6-10 There glitched)
2.Upgrade your weapon with the cards just like you would with a sunstone
From +1-3 the item wont break but after +3 you need spros in case of weapon breaking.
After +4 Its starts to glow and the higher the element, the higher is he glow and more damage against opposing elements.
