Okay so I was chatting with ca25 to try and get to the bottom of hailstorm. Here's what I have

[11:32:26 AM] ca25nada: +13 from regular upgrade
[11:32:39 AM] ca25nada: lizard / deadly for enchants (which are just crits)
[11:32:47 AM] ca25nada: +59 int from artisan
[11:32:54 AM] ca25nada: +68 matk from special
[11:33:01 AM] ca25nada: +36 matk from reforge
[11:33:07 AM] ca25nada: 7.5 int from reforge
[11:33:13 AM] ca25nada: +8 hailstorm min from reforge
ice elemental on staff
380 Magic Attack is what she said she had in her stat window.
r1 Ice Mastery, r1 Hailstorm, no rosemary gloves
27,000 crit on 1/0 enemy, 10,904 on 1/0 enemy
10,910 normal on 0/0 enemy
Trying to work with that
[300 + (380 * 3.2)] * 6.25 * 1.15 = 10,896
Which is fairly close. I was kind of hoping for a more generous formula, I don't see this one having a significant boost for magic at all. It's quite similar for your second post.
[300 + (192 * 3.2)] * 6.25 * 1.15 = 6572
Edit: 6572 / 6.25 (1 charge) is 1051. They're all fairly close.
