Various Strategy Tips
Tip 1: Coins can be acquired by defeating enemies and searching pots. You can also obtain Weights and ammo by destroying pots, so be sure to break open any you find.
Tip 2: Before taking on the ruins, be sure to purchase a Hand Scanner. This item will absolutely be required for finding and solving the various mysteries and puzzles hidden within the ruins. Once you get the Hand Scanner, try inspecting not only stone tablets, but background objects, skeletons, and other things you come across. You may be able to find some crucial hints in some strange places.
Tip 3: Be sure to read the messages on Xelputter thoroughly. You'll get hints to help you on your adventure.
Tip 4: Pay close attention to your remaining health. When it starts getting low, either return aboveground to enter a hot spring and replenish your health, or collect the green Soul Stones that appear when defeating enemies till the meter fills up and replenishes all of your health.
Tip 5: Be sure to read any Holy Grail Tablets you find. Once you've read a Holy Grail Tablet, it will be registered as a warp point. So make sure to read them as they'll make your adventure a lot easier. Also, don't forget to save your progress.
Tip 6: Seek out and install Mobile Super X3 apps. Apps can't be used unless they're installed. Also, there are apparently some secret functions that can be unlocked and used by loading multiple apps simultaneously.
Tip 7: Take advantage of the recently tourism spot-ified La-Mulana ruins and brush up on your adventuring skills. If you can manage to explore the La-Mulana ruins, then you're already well on your way to becoming a top archaeologist. And don't forget: you are, first and foremost, an "archaeologist". Don't miss tiny, subtle changes and suspicious spots within the ruins - there's almost always something there!
