Yes. Talismans are useful regardless of what you do (well, maybe not regardless, but for spiritual powers like Lucians or just magic, Talismans carry a variety of uses and are different wherever you use them). 

Like for spiritual powers, think the sutras that Miroku from Inuyasha throws (that depend upon the spiritual powers you have. Lucian would find usefulness with them, but he already has alot to focus on. 

For magic, its more like creating symbolic items that contain special magical powers (that are usually one shot affects that vary upon what type of magic you use). Still useful nonetheless.
