Copying such a complicated mess would be really difficult. From the size of the projection, Angor could tell that it was used on medium to small sized items.
Drawing a rune on a small item such as a golden bolt required Angor to shrink the rune according to equal proportion. A full-sized "Prelude to Elimination" already looked like an ink puddle. Any smaller, and no human eyes or pens would be useful to work on it.
However, that was not a problem for now. First, Angor needed to draw "Prelude to Elimination".
Instead of doing it right away, Angor picked up Enchantment Cyclopaedia: Advanced and kept reading.
Despite its complicated pattern, the outcome of the magic array was quite simple: when triggered, the enchantment would release a low-frequency sound wave which would then disrupt the already chaotic energy inside undead creatures to eliminate them.
