Activity: Managing your Library | …

The spells that you add by Spell List Collection as you gain levels reflect what you've learned or gained during your adventures, as well as breakthroughs as you understand the multiverse. You could discover a spell recorded on a scroll in an evil wizard's chest, or in a dusty tome in an ancient temple devoted to a god of knowledge. When you find such, you may be able to copy the spell into your Collection.

Copying a Spell into your Library

Suitable spells to add to your Collection must be of a Spell Rank you can prepare or use (via the Spell Library or Spell Repertoire common features), Once you find them all you need is the time and resources to decipher and copy them.

For each numbered rank of the spell, the process takes 1 hour and costs 10 gp per spell level (Cantrips take 10 minutes or a Swift Rest). The cost representing the material components, inks (for spellbooks), time mimicking or teaching the spell (to entities and familiars), and whatever else may go into your Spell Collection. Once done, however, can prepare these spells just like any other you have.

Replacing your Collection

You can copy a spell from your own Collection into another form of your Collection (one spelbook to another, for example, if you want to make a backup of such), This is just like copying a new spell into your Collection, but faster and easier, since you understand your own notation and already know how to cast the spell. You need spend only half the time and cost to do so.

If you lose your connection to your Collection (like losing your spellbook, having your connection severed from your familiar, etc), you can use the same procedure to transcribe the spells that you have already prepared into a new form of Collection. Filling out the remainder requires you to find new spells to do so, as normal. For this reason, many wizards keep backup spellbooks in a safe place, with those who rely on familiars need only to find a new Familiar and teach them anew.

Adding Spells to your Spell Library / Prepared Spells goes along with the this feature common feature, which you will get along with the Spell Library feature unless under different circumstances.
