Heh, I think it's the only attack-all ring that actually hits her. At the level you're at without grinding (and assuming you have been finding most of the Magirocks), you can literally take her out with nine Elec Rings. She won't even get a chance to move. Just make sure to wait until she's actually vulnerable. I think I was like Level 22 and each of my Elec Ring uses did 50-60 damage. I think she's only got like 400 HP. Even if you're doing a little less (I was initially at Level 20), the Elec Rings will make the fight significantly easier even if they don't kill.Tell me more
Also, if you're underleveled, swap out to the Light Rod. It will at least do 2-3 damage, as opposed to the 1 of everything else.
