Soulstone

Soulstone is the crystallization of the ethereal element in the blood of all legendary monsters. Although all legendary monsters carry the essence of soulstone in their blood, it is not always guaranteed to obtain it after slaying the monster. Yet, to be extracted, the legendary monster must be killed. It is the source of all magical powers and all magic-users get their magical powers from a soulstone bound to their souls.

There are two types of soulstone; sliver and shard. And when ground, it turns into souldust.

One can consume a soulstone shard to either to increase HP, or to increase the number of spells accesible. (Roll a d6 and add the roll to your HP/available spells)

Consuming a soulstone carries the risk of corruption. After the consuming ritual of soulstone, which takes a whole day, and requires one full week of rest, roll a FORT and a WILL save. If both saves fail, roll d66 for the corruption effects.
