No of attempts varies - but you can see that in the value of the BP discovery. The real question in my mind is if they're worth crafting at all ... I only see the ingredient reqs on the ones I got and frankly speaking at 40-60 crystals per attempt and 6 different crystals type required by a lvl I bp is hard to see those worth craftin at current crystalz MUs of 2-10K% :) ... I was out all day killin stuff to get crystalz and after a long killin spree I'm far from having enough for even 1 attempt :( Either make crystalz as mining loot, either increase the drop rate and qty or change the refining rate to 1:10 or 1:100 or - simplest - lessen the BP reqs (I'd recommend cutting the last zero in crystalz required :) ) ... you guys did a good job on NI with the last release but u need to make those new itemz craftable as no one will pay even 1k% for a L knife
The ingredients could make sense for a handgun with insane eco, so that it could be sold with high MU to cover the crafting costs and still be comparable to items from other planets. The way it is now, it's simply not worth to craft them. Pity.
