Getting a little further into the magic system here in this one.  I concluded that Ishar’d need a specialized weapon if she wanted to effectively channel her affinity – so while her short stave doesn’t look like much, it’s actually steel wound with wire and coated with an outer shell; i.e. that’s an electromagnet she’s carrying around.  She can do all sorts of fancy tricks with it beyond just turning it into an electric polearm, though that’s obviously what she uses it for most of the time.
