Hello, I was recently trying to attach multiple Rune of FO, copper "Charm Animal" to an item, in this case it was a mallet, and I got this message after failing multiple times
You start to use the rune on the mallet.
A small rune created from resources on Jackal and infused with the spirit of Fo. It is glowing from the heat. It will activate the charm animal effect one time.
You try to use the rune on the mallet but fail.
And after wasting in total 3 Rune of FO, Copper "Charm Animal". I finally managed to succeed but in fact it was in vain ...
You start to use the rune on the mallet.
You can't use the rune on that.
So basically it was impossible to attach it on from the first place and I lost my Runes of FO, I didn't know I had to use it directly on a pet.
