GW2 Chain Whip Sword and Mad Scientist Outfit are now available in the gemstore for 600 and 700 gems respectively.
Chain Whip Sword – 600 gems
The whip like animation is only present on some sword ability animations (see video). Sword skin is only in the gemstore for 7 days so might want to get it soon (it will return later probably).
Mad Scientist Outfit – 700 gems
The test tubes are animated (see video).
