400mil?
seriously? y is that?
15m for one ice pick.
Success chance for +10: (60%, 50%, 50%, 30%, 30%, 20%) -> 0.27%
Attempts needed: 1/0.0027 = 370.
... wait, I think there's something wrong with my maths, it should cost way more >.<
Yeah the math is a bit wrong as is the success chances.
Success chance would look like this from +1 - +10 being that an IP is a lvl 4 weapon.
(100%, 100%, 100%, 100%, 60%, 40%, 40%, 20%, 20%, 10%)
Attempts needed would be :1/0.000384
So the average amount of IPs that you would need to go through to get one to +10 would be 2604.1667. So it should should be worth quite a bit.
