The most powerful mages are able to focus their powers and store them in
artifacts for later use. Using the skill repeatedly allows the mage to
reinforce the stored spell and make it stronger. 'Store consider' allows
the mage to estimate the potential of an object for storing magic. 'Tap'
is used to invoke the stored spell. 'Store cost' shows how much mana it
would cost to store the given spell in an object.

Note that the stored magic will gradually diminish and eventually vanish.
