Item effects being triggered

Ask your troupe whether this is possible in your saga. It is tmk nowhere stated, that it is.

In RPGs, you can always find loopholes breaking the story, if you allow everything not explicitly ruled out.

If you do not allow the result of an ArM5 p.99 Linked Trigger to trigger several effects, and make sure that an effect can provide a result and thus trigger another effect only after it was successfully cast and took effect, you can do away with the most dangerous kinds of pom-pom-wands, maxim wands and mitrailleuses in Mythic Europe.
