Just a quick gunslinger question

[Ngjoko]

ok, my example:
type : Shotgun
dex : 100
weapon: Black Rose +6[1]
ammo : Silver Bullet
attack : 395(200+180+15) +18(6x3)
skill : Full Buster(10), 1200%

so max damage estimation of this skill under normal circumstances: 4956
*do note that this skill has no cast time, just heavy aftercast delay.*

So, we try Hill Winds
HP : 4233
Def : 10 +31

Estimate max damage:
(4956 x (100-10)%) - 31 = 4429

This can OHKO Hill Winds, but not always since there's still minimum damage that i don't really know how to calculate. If you introduce earth in to the equasion.

Estimate max damage:
((4956 x 200%) x (100-10)%) - 31 = 8889

If you decide to slot in a Mandragora Card into that shotgun, max damage estimation:
(((4956 x 200%)+20%)x (100-10)%) - 31 = 11863

instant death with 2880% of attack power, but this move is just a 1 hit skill.

You're a slinger, you should know that Desperado do more that just 1 hit, even if it's only 1728% per hit(on a Windy Clamourous Garrison +6), you can deal up to 17280%, which you can destroy a huge mob of Hill winds instantly, heck even harpies will be destroyed by an earth elemental Desperado(just change the clamourous into Decussate).

I'm not a skilled calculator, but this is what i get. Any experienced calculators please verify this.
