Not sure if its ok to link to another site, but they just updated with some old and new(atleast to me) info on the front page.
Up next: BATTLE REGIMENS!
A regimen for strategy
When fighting a powerful opponent with your party, you can use a system called “battle regimen” to link your attacks with the attacks of other members in your party. This has a chance to add special effects. Here’s how it works:
1.Decide the order of attacks by discussing it with your party
2.When your turn in the regimen comes, press the button next to the action meny to change to regimen mode, and select your move.
3.When all members have entered their moves, someone presses the button to activate the regimen.
4.Depending on the actions and order selected, effects may be added.
Moves in battle regimens do not need any special properties. For example,
a gladiator’s slashing attack and a marauder’s axe attack gave the enemy a “physical defense down” status effect. The same effect was produced when the marauder changed to pugilist and used a regular punching attack. The effect changes depending on the order and the skills used, so I’m looking forward to finding the best combinations. In this experiment, we only used regular attacks, but it still lowered the enemy’s defense. Battle regimens using elemental attacks and magic will surely have even more powerful specialized effects.
This should be pretty cool. I'm interested in how it will work out.
