Mass Production

is an Tradeskill Alternate Advancement ability that can be chosen as you advance in your skills.

About
is an "end line" ability in the Prestige tab of the Tradeskill AA tree. If you press L to open the AA tree while in-game and click on the Tradeskill Prestige tab, it is one of the three abilities at the very bottom, on the far right side.

After enough points are put into this tree, the tree bottom options will "unlock" and show in color. You can put 1-5 points in the ability, with each point allowing you to mass produce 20 items while crafting per point, with a maximum of 100 items. Put another way: for every point put into Mass Production, you can make 20 items at once with a multiplier of five.

This elective tradeskill ability is highly useful for anyone who:
 * spends a great deal of time making large quantities of items for guild members, friends, or broker sales
 * enjoys decorating player homes, when mass producing items like building blocks to build a unique structure.

Use
Once you have this ability a new element is added to the tradeskill window (see image to the right). After you select the item you want to mass produce, a drop-down arrow labeled Quantity appears in the bottom left side of the tradeskill window. Depending on the number of points added to the Mass Production AA ability, you can choose:
 * 1-20 items (one of five AA points)
 * 1-40 items (two of five AA points)
 * 1-60 items (three of five AA points)
 * 1-80 items (four of five AA points)
 * 1-100 items (five of five AA points)

Limitations
There are some items that can not be mass produced. These are typically lore items, which you can only ever have one of at a given time or items that are for quests. For example, you can not mass produce ten stones for a quest if it requires that many; instead, you must produce a single item at a time.
