To my knowledge a piece of gear takes 2 hours to get at lv 20 and a weapon around 3 hours so, yes it's not a long grind, the grind was frontloaded on the levelling, as said in other threads they addressed the complaint of sebsequent relics requiring the same amount of grind to be acquired, whatever that was a good or bad move is up to ppl, I will say it's bad for eureka's health overall
