After a tough first day (was more focused on 3-starring maps and seeing which Map was farmable), I finally caught up to the pace after splurging Day 2. With Day 3 now over I'm at 336 Dragon Fangs, 13 Sacred Crystal used. I can pretty much keep my usage to 4 and under the rest of the way and I should stay ahead of the 107 per day pace to reach 1500 Dragon Fangs.
