Ooo, this is a good idea, trading all those bills and stuff to help stock up on the type you need.
People can
check here on Mysterytour to find out which kinda stuff they will need.
For Relic Sword > Dynamis Sword you need:
4x M. Silverpieces
14x 100 Byne Bills
That's gonna take like forever, lol. In gil, that is about 18,000,000 gil worth of stuff alone, not including the extra few materials you need. Assuming you want to do this PURELY by winning lots on the 100 bills in dynamis alone:
Usually I see 2 of these drop per raid, but sometimes 1. Assuming 2 will always drop, that 50% of the raid intend to lot on AF, and there are 60 people on the raid, you have a 1/15 chance of winning one per raid. Goto both raids and this is about 1/8 (rounded up) per week. That is 2 months per 100 bill, and as shown above, you will need about 18 of them, so it will take about
3 years of non-stop Dynamis Runs to collect that many bills.
So, in conclusion, don't expect to just stock up on bills and get anywhere, lol. Been a long time since i did some hardcore farming, last was when i first discovered ZiTah (man, that place was bliss when i started there, nobody else knew about it but the odd JP you might see... I was able to make 3-4 stacks of cuttings a day, lol...)
I was thinking of joining the Cap fishers in Rabao, Cyntari makes a huge amount of gil there a day. My smithing skill is high enough for it, I just need to get my fishing skill up from 18 to something decent like 50.
