Pet Tiers has a mathematical error in the Rammy section. It should be 16, not 15. If you do see this, please edit Rammy to be #11 with 16, and Bitey Bat with #12. I would do it myself, but it's protected from editing.
It was on my open face gray knight when I was testing my combos in cyclops cave and I got like 4 shocks well before hitting the conheads/slimes 80-100 times. Do you mind testing it? I think the Fishing Rod may have a shock chance as high as the cattle prod or something now.
