I crafted my nightblade yesterday, and have only gotten to doing half a lvl with it so far(due to ENORMOUS lag -_-) but when i checked the heat lvl today, it said lvl 6. its not like im mad or anything; i just want an explanation for this odd appearance. i did rev quite a few times today, but im pretty sure that even if u revved someone with infinite heat 10 times, u would not pass lvl5.
It depends on where this half-level is. Half of D26 or D27 in FSC is more than enough to level a 3* to level 6 if the rest of your gear is fully heated. A person in my party a couple of days ago went into D24 with an unheated Gunslinger Sash, and went up at the elevator so they can craft it to a Sunset Duster. IIRC, the Duster was also level 6 by the time we got to Vana.
