Preservation

Preservation is a legacy skill that was introduced during T5 that allows food cooked in a Kitchen to be bagged so that it may be carried in a players inventory.

The skill is available from any School of Worship and costs 50 Papyrus Paper to learn

A meal may be either be bagged (costing 1 Papyrus Paper per serving) or boxed (currently unknown, expected to be one Jug and one Bottle Stopper).

A bagged meal will remain fresh for 4 teppy-hours, a boxed meal will remain fresh for 24 teppy-hours.

Note that if you are pinned when consuming a preserved meal you may not automatically become unpinned. If this happens, drop 1 item and pick it back up.

From System at time of release:

The Preservation skill is now available at Schools of Worship, to those Level 14 or higher.
Preservation allows one to package a meal to go, either in Papyrus Paper (fresh for up to 4 hours), or a stoppered jug (up to 24 hours)
Box lunches return the packaging materials, Bag Lunches do not.
The tuition for Preservation has been modified - it's now just 50 Papyrus Paper.
