Elemental soulstone

Uses

Gleaming Multicolored Soulstones are used to enter Elemental Confluence. It takes 10 'souls' within the soulstone to enter.

Charging

You must WEAR the Gleaming Multicolored Soulstone to charge it. From that point on, it's simply a matter of killing elemental creature types.

Only the individual who gets the final hit on the elemental can charge his/her soulstone. There is no advantage to grouping when farming elemental souls.

Each kill is equal to the creature's level. 100 creature levels = 1 soul within the soulstone. 10 souls are required to enter the Confluence. A soulstone can hold 100 elemental souls, or 10,000 creature levels of kills.
