Rune essence (Runespan)

Rune essence is obtained in the Runespan through the floating essence that randomly appear in the plane, or by chipping or depleting a creature living in the Runespan.

You may only take essence from floating essence clouds if you have less than 25 pieces in your inventory, as clicking "Collect" would bring the number up to 25.

When you deplete an essence creature, you will receive 50-150 pieces of essence.

You can also chip an essence creature to obtain small amounts of essence. This is not recommended due to the fact you need to pay some runes to create essence this way. For example, chipping essence from a mind essling requires ten air runes. Also, depleting essence creatures gives more than enough essence to siphon with.

If you choose to destroy your rune essence, all of the rune essence will be destroyed when clicking yes, even though there is an all option.

If you try to bank any runes or essence from Runespan you get the message "A magical force prevents you from banking this item."

Trivia

 * Unlike normal rune essence, these are stackable.
 * The destroy option states that a player is able to "...get more by siphoning from floating essence and siphoning from runic creatures." however you collect from the floating essence, rather. It is unknown whether or not this a glitch.
