Choose any design of runic script to which you have already applied the Design Focus feat. Any scripts you cast of this design are very hard to resist.

Prerequisite: Design Focus

Benefit: Add +1 to the Difficulty Class for all saving throws against scripts from the design of runic script you select. This bonus stacks with the bonus from Design Focus.

Special: You can gain this feat multiple times. Its effects do not stack. Each time you take the feat, it applies to a new design to which you already have applied the Design Focus feat.
