Local Enemy Bestiary
Once in the mine, head northward, but pay attention on the left to find a blue sparkle. This is a Save Point. Here, you are able to use Sleeping Bags and Tents, and are able to save the game from the menu. I have an idea: use it.
Afterwards, continue north for a while. Eventually, you’ll reach a barrier. Examine it and Biggs will knock it aside, letting your first boss, of sorts, have a nice shot at you.
Ymir can use a basic and weak physical attack, as well as Slime , which can damage and induce Slow. Its shell is a separate entity; in other words, it has its own attacks and stats. However, all it does is use Megavolt , which can easily take out about 30% of your party’s HP (rough estimate; no definite percentages are dealt with).
I will also note that you can kill the shell. Megavolt can only be used six times with 120 MP, so it costs 17 ~ 20 MP. After that, you’ll be safe in attacking the shell. If you want an Ether that bad (it takes more time than you’d think), go right ahead you crazy person, you.
If you opt for that strategy, go ahead, but don’t use a Thunder-based attack unless you want to undo some work.
There is another way to go about this. Simply attack the head, instead. It will take much less time. All you need to worry about is when, every now and then, the head retreats into the shell. Just let everyone’s ATB gauge fill up until the head comes back out. Then continue attacking. By the by, consider using Magitek Missile when it is ???'s turn.
Continue northward after the battle to come across a large crystal … the Esper, frozen for a thousand years. As you approach, your ??? character starts to act freaky and her companions vanish. Then the Esper does something to the ??? character, making her Magitek Armor explode and her black out…
