Excavation Duty

Walkthrough
Destroy all of the Brittle Rocks.
 * You start at (G-11).
 * The party will proceed to the wall at (G-10) and destroy it.
 * After the (G-10) wall is down, typically one party member will head to the northern wall at (G-6) to solo it. The rest of the party will destroy the wall at (H-8) and the two at (I-7).
 * For specific strategies about how to destroy the walls, refer to Assault Mission - Excavation Duty/Strategy
 * Qiqirn Mines will take out the wall in one shot.
 * Both kinds of Qiqirn drop Qiqirn Mine temporary items.
 * To use a mine, have the person engage the Brittle Rock, use the Qiqirn Mine on it, and stay engaged while it blows it up.
 * The mines appear immediately in a player's inventory, without going through the treasure pool.
 * The drop rate of these mines may be affected by Treasure Hunter and Moon Phase; you can get more or less than the 4 you need if every Qiqirn is killed.
 * Having a bomb Self-Destruct by a wall WILL destroy it completely.
 * The bomb must be extremely close to the wall when it blows up. If it is too far away, it will have no effect on the wall.  Getting the positioning correct is said to be difficult.
 * You may also need to engage the Brittle Rock for Self-Destruct to take it out.
 * The Rune of Release appears at (F-10).
 * It takes roughly 2:45 to run from the furthest Brittle Rock at I-7 to the Rune of Release with quickening active. This time will vary if the runner does not have invisible and needs to wait for bombs to move.
