Re: How to pass all the maps of Yuidora Mine ?
Sealed ground may take a few attempts to work out the best strategy.
If it's early on in your character development and you don't have double-move skills, try to pick the low movement characters when you only need to move a few squares to reveal more terrain.
Then you can use the high movement characters to go past them and reveal more of the map.
When you capture a point, it helps if you remove the character so you can bring in a fresh character and start moving again in that turn.
FYI. It can be completed in 2 turns if you use the right characters. (possibly even 1 turn)
If I remember correctly, Dark Road is the one with only Wil and the Heroines on the first entry at different corners of the map?
Because of that, you need to be at a high enough level to have your characters defeat the monsters they come across on their paths towards the center.
Since each character is isolated on their path, you should also choose the appropriate weapon for defeating the copies.
It may take a few attempts to get through and if you can't do it then you may just have to wait until you've leveled your characters more.
This one is just a straight fight.
