There is a pretty cool thunder effect you guys can use for the fang gem. You get this effect sometimes when you land a critical hit. Here is a link to see this effect:

Reasons to use this effect over another bracelet:
1) This animation effect already exists in game so it would be easy for you guys to make it the effect for fang gem
2) Full effects look better
3) We have too many bracelets and not enough full effects

And one more thing. Please make the real black street outfit. Use the romancer outfit/green street outfit as the design and just change the colour to black.
