Let's Play Genius of Sappheiros (Weekend) Part 19
I spend most of the video going over what I got through grinding. I was lucky enough to have enough elemental shards to make into elemental crystals and make two suits of 140 Defense armors which is extremely high for this point in the game. Plus they give near immunity to their given element (decided by the crystal you use to craft).
It definitely pays to look through what you can synthesize. With just two Pretty Mirrors, I made a shield that blocks anything with rather high stats.
Now onto Eientei...
The first half of this dungeon requires two separate groups going at the same time. You swap between the parties by hitting select and you cannot access your Equipment unless you have a group at the save room before the boss.
I made a mistake when I got the A and B groups mixed up. I was looking at the wrong letter in the menu. In any dungeon, the screens are assigned a letter as well. This can help if you are searching for specific spawns in a dungeon. So the Alice group is infact group A but the screen they start in is room B while Group B starts in screen A. Confused yet? Good.
Just know that the first party you form needs to be focused on magic damage and your second party needs to be focused on physical. You can mix it up some but majority of the enemies you will face will be more vulnerable to either magic or physical.
