Hello, dear DF-Fans!
There is something I've been asking myself since the book (can't remember the title) where Harry is at the Larry Fowler Show with Ortega and the Priest. He is using a spell that suppresses bis magic. He has to concentrate a lot to keep it going.
And we know, there are at least two kinds oft thorn manacles (fae made and those with iron, Nicodemus used in Skin Game).
So maybe a wizard could make a magical item without thorns to keep a magic suppressing spell going, like for example the shield bracelet helps keeping the shield going.
That way a wizard could use technology if he wanted to. He would just have to activate bis suppressing bracelet/amulet/chosen focus item. Without pain.
What do you think?
