We all know the feeling when you're hunting fire crystals when every item you have is at the point where heat doesn't help and you open up a bunch of boxes and get nothing but heat.
I would like to propose that Fire crystal drop rates increase a small amount (somewhere around 3 to 5 percent increase) for every item equipped that needs to be forged. This rate would not be affected by weapons in the 3rd and 4th slot though. This rate would also not be affected by fully heated items that need to be alchemized.
The thread's about suggestion's for crystal srop rate's never go so good these day's as there are hundred's. Check out mine, I got no replies.
