Like I said, I enjoy spending money on reasonable purchases (the magicite purchases are so, they give you a nice boost that is otherwise impossible to gain in such a short time). The amount of money you have to spend on lapis is, imo, unreasonable, but would be more reasonable if they had specials every now and then for more lapis or more evolving materials. As I said before, it was one piece of one awakening material, not an entire stock. I did eventually get it, but it took a couple days of just doing the awakening vortex, without doing anything else. I'm just worried that Bartz was the easiest and that when the others unlock the ability to get 5-stars (they haven't yet for some reason), I'll have to stop playing the game for a week or so to get them the last few materials they need. However I will say I am very happy with how fast energy recharges. At rank 20, two and a half hours later and you've got a full bar again. Energy is quite generous.
