I think I know what to put in Fiona's talisman the same season that she's installing the Accio Talisman. Basically, Repel the Wooden Shafts (p.138). However, it's a Voice Range. I seem to recall something in the enchantment rules that if an item has an effect that's Voice range, it has to be able to make noise, but I can't find it. If it's measured from the wielder's voice, saying the command word, then I can install the effect with 24 uses a day and use up all the remaining levels. If not, I'm going to have to come up with something. Anybody else remember this and can point out where it is, or am I daft?
