Just cleared floor 13 in Nero Tower. Woohoo!!
Those last two floors were definitely tough. Didn't think I was going to make it on both floors, but it actually happened! Definitely feel like I earned my brick!!
Dejnov.
Edit: Just spent the brick on LBing Michael's spear (to 75) and right after spent three gacha tickets from the Nandi event. What should also appear... another Michael spear. WOW!! Sometimes this game just gives you crazy luck (other times you spend money and get squat...).
