10 points
You have access to a magical artifact of great power known as the Spellcrux. You use it through your Spellcrux Focus (a small item of any kind). The major benefit of this is that you may draw spells from it to use for your own purposes.

This advantage is only available as part of membership in the Arcane Order of Enchantment and Exposition, more commonly known as the Wizard's Guild. It is detailed here due to the complexity of this advantage.

Calling a spell forth requires 1 second for every ten points of the spell (round to the nearest whole number of seconds). For every point worth of spell you draw, you must replace them by casting any spell of equal or greater points into your focus. You may bank the points ahead of time if you wish, but anything above 34 points is ignored.

Spells higher than 34 points may not be stored or retrieved from the Spellcrux. Attempting to store a more powerful spell will fail and result in 1d damage to you as the energies feedback into you.

Combat-oriented spells are prohibited to be placed within it and will be bled away by the Regent that maintains the Spellcrux when she notices them.

You may draw no more than 34 points in a single day. Failure to replace what you take prevents you from using the Spellcrux once you exhaust your 34 point allotment. If you've banked points ahead, you could draw up to 68 points before having to recharge the Spellcrux.

You may determine which spells are currently available by concentrating for 10 seconds. Certain spells will always be available, except perhaps in times of dire emergency for the Arcane Order (this has never happened before, to your knowledge).

To use your focus, you must be in physical contact with it via skin. No one may use another's focus, since they are attuned specifically to their owner.

This functions slightly differently for some types of Magery:

Standard Magery: You may use your focus to prepare a spell very quickly. You need only have the appropriate number of points unprepared and know how to cast the spell you're retrieving. Retrieving a spell you don't personally know causes it to fizzle when you attempt to cast it.

All Others: You may cast spells directly from your focus instead of spending your own energy on it. This requires the time listed above to draw the spell out. Trying to draw a spell you don't personally know will cause it to fizzle.

Each Spellcrux focus is a magic item and may be neutralized as such. However, regardless of the method used, this merely causes it to become dormant for up to 1 minute. This is due to the fact that each focus is a small extension of a very powerful magical artifact that can't be dispelled so easily.
