Editing HorizonVirtual:Arcane Rewrites (section)

==Programmer Rewrites and Borrowed Datapads==
A programmer can use a borrowed datapad to prepare a rewrite she already knows and has recorded in her own datapad, but preparation success is not assured. First, the programmer must decipher the writing in the book (see Arcane Rewrite codes, above). Once a rewrite from another rewriter’s book is deciphered, the reader must make a Codecraft check (DC 15 + rewrite’s level) to prepare the rewrite. If the check succeeds, the programmer can prepare the rewrite. She must repeat the check to prepare the rewrite again, no matter how many times she has prepared it before. If the check fails, she cannot try to prepare the rewrite from the same source again until the next day. (However, as explained above, she does not need to repeat a check to decipher the writing.)

===Adding Rewrites to a Programmer’s Datapad===
Programmers can add new rewrites to their datapads through several methods. If a programmer has chosen to specialize in a school of rewriting, she can learn rewrites only from schools whose rewrites she can execute.

'''Rewrites Gained at a New Level:''' Programmers perform a certain amount of rewrite research between adventures. Each time a character attains a new programmer level, she gains two rewrites of her choice to add to her datapad. The two free rewrites must be of rewrite levels she can execute. If she has chosen to specialize in a school of rewriting, one of the two free rewrites must be from her specialty school.

'''Rewrites Copied from Another’s Datapad or a Scroll:''' A programmer can also add a rewrite to her book whenever she encounters one on a rewriting scroll or in another programmer’s datapad. No matter what the rewrite’s source, the programmer must first decipher the rewrite code (see Arcane Rewrite codes, above). Next, she must spend a day studying the rewrite. At the end of the day, she must make a Codecraft check (DC 15 + rewrite’s level). A programmer who has specialized in a school of rewrites gains a +2 bonus on the Codecraft check if the new rewrite is from her specialty school. She cannot, however, learn any rewrites from her prohibited schools. If the check succeeds, the programmer understands the rewrite and can copy it into her datapad (see Writing a New Rewrite into a Datapad, below). The process leaves a datapad that was copied from unharmed, but a rewrite successfully copied from a rewriting scroll disappears from the parchment.

If the check fails, the programmer cannot understand or copy the rewrite. She cannot attempt to learn or copy that rewrite again until she gains another rank in Codecraft. A rewrite that was being copied from a scroll does not vanish from the scroll.

In most cases, programmers charge a fee for the privilege of copying rewrites from their datapads. This fee is usually equal to the rewrite’s level x50 gp.
'''
Independent Research:''' A programmer also can research a rewrite independently, duplicating an existing rewrite or creating an entirely new one.

===Writing a New Rewrite into a Datapad===
Once a programmer understands a new rewrite, she can record it into her datapad.

'''Time:''' The process takes 24 hours, regardless of the rewrite’s level.

'''Space in the Datapad:''' A rewrite takes up one page of the datapad per rewrite level. Even a 0-level rewrite (cantrip) takes one page. A datapad has one hundred pages.

'''Materials and Costs:''' Materials for writing the rewrite cost 100 RU per page.

Note that a programmer does not have to pay these costs in time or gold for the rewrites she gains for free at each new level. 

===Replacing and Copying Datapads===
A programmer can use the procedure for learning a rewrite to reconstruct a lost datapad. If she already has a particular rewrite prepared, she can write it directly into a new book at a cost of 100 RU per page (as noted in Writing a New Rewrite into a Datapad, above). The process wipes the prepared rewrite from her mind, just as executing it would. If she does not have the rewrite prepared, she can prepare it from a borrowed datapad and then write it into a new book.

Duplicating an existing datapad uses the same procedure as replacing it, but the task is much easier. The time requirement and cost per page are halved.

===Selling a Datapad===
Captured datapads can be sold for an RU amount equal to one-half the cost of purchasing and inscribing the rewrites within (that is, one-half of 100 RU per page of rewrites). A datapad entirely filled with rewrites (that is, with one hundred pages of rewrites inscribed in it) is worth 5,000 RU.
