I love the Idea but what exactly do they do?

Soulshards are used to create clones in the Clone Garden. They can also be sold on the market and you can give them to your coven, just like donating money. You can still receive them by hunting humans and through PvP.

okies thanks sin!

Soulshards

1. Get from attacking PVP, or Hunting, NOT clones.
2. You can use them to make gear (crafting), make Clones (Clone Garden), sell on the market, or donate to a coven.
