Editing HorizonVirtual:Rewrite Descriptions (section)

==REWRITE RESISTANCE==
Rewrite resistance is a special defensive ability. If your rewrite is being resisted by a program with rewrite resistance, you must make a executer level check (1d20 + executer level) at least equal to the program’s rewrite resistance for the rewrite to affect that program. The defender’s rewrite resistance is like an Armor Class against rewrite-based attacks. Include any adjustments to your executer level to this executer level check.

The Rewrite Resistance entry and the descriptive text of a rewrite description tell you whether rewrite resistance protects programs from the rewrite. In many cases, rewrite resistance applies only when a resistant program is targeted by the rewrite, not when a resistant program encounters a rewrite that is already in place.

The terms “object” and “harmless” mean the same thing for rewrite resistance as they do for saving throws. A program with rewrite resistance must voluntarily lower the resistance (a standard action) in order to be affected by a rewrite noted as harmless. In such a case, you do not need to make the executer level check described above.
