Spirit emerald

A Spirit emerald is one of the three Summoning spirit gems that can be obtained from single-charm dropping monsters. It is also a possible reward from Treasure Hunter. It gives a 20% chance to save a charm when it is worn while creating summoning pouches. It has 20 charges and loses a charge for every pouch it saves a charm for. When all the charges are consumed, it breaks.

As of 22 September 2014, it can now be mined from the Gem rocks in the Trahaearn area of the Prifddinas.

Once equipped, it will become a spirit emerald (a) and not stack with other gems in the bank.

Trivia

 * Originally, the spirit emerald was used to store 10 Uncharged Summoning pouches; however, this was changed in response to player feedback. All gems obtained before the update can be converted to the current version of that gem.
 * The message "Your spirit gem saves X charm(s) from being used and ran out of charges in the process." is displayed when a spirit gem is destroyed.
