Glass Cannon

Made of hardened volcanic glass, this rune arm fires conjured stones which will explode violently upon impact.

Update 39 (2018) Rune Arm Upgrade
You may convert your pre-U39 Glass Cannon to the U39 version by talking to Euphonia Teles and telling her I have some old gear I'd like to freshen up. This conversion is free using the Conversions of Crystal Cove barter box.

Legacy Version

 * Note: The pre-Update 39 (tiered) versions are available from the Dusty Old Treasure of Crystal Cove.
