A little more info on the Magic Circle system
- If one of the characters in your party stands in a magic circle, the character's weapon will temporarily gain the status element of the magic circle (i.e., sword becomes fire sword).
- Elza has a wind-based ability that allows him to spread the magic circle, which will have different effects. Anoop says the example given in the magazine is that it would cause enemies to sleep.
A
2ch summary post on known info on the game says that spreading an ice magic circle would cause enemies to
slip, which seems to make more sense to me.
The impression I get from the google translation of that 2ch post (always dangerous, lol), is that there are probably going to be normal weapons that aren't affected by the circles(neutral) and then "magic weapons" which will be affected by the circles.
