Source

This item drops from Master Elemental Shaper Krixix in Blackwing Lair.

Teaches

• Smelt Elementium

Notes

• Although this item only drops once each time Krixix is killed, several players may acquire the book as Krixix has a 30 minute respawn-timer. If you didn't get the book last time it dropped, just return to the Blackwing Lair later before the entire instance is reset and kill Krixix again.
• This is one of the only two blueprints used in mining. The other one is [Study of Advanced Smelting].

Patch Changes

Patch 3.0.8 (2009-01-20): Added.
            This item was added so a priest would no longer have to mind control Krixix to teach the ability to other players.
