Update for combat system. In short, grid based. You and the enemy have 2 rows of 4 squares each in which to position your dudes. Attacks and abilities from a PC/NPC in your party affect one or more of the enemy squares at a certain range, depending upon lots of things.
This attack pattern is something you'd find on a sword thrust attack, and indicates it will attack forward, striking the closest enemy directly in front of it, up to two grid squares away. Other abilities may be able to pierce multiple targets, may strike from different directions, or be able to directly target an opponent regardless of their position (this is especially true of magical attacks). In game, you'd see a helpful targeting indicator show you the range of your attack, along with who'll ultimately be affected.

Which characters should I use to tank damage from each enemy? If an enemy is charging up a powerful attack, should I try to move someone into position to interrupt him or should I move everyone out of the way? Should I move my character into position to attack a critical target next turn, or should I just stay put and attack whoever is in front of me this turn? Should I cluster my team together to share short range buffs, or should I spread them out to avoid AOE damage?
This applies to magic and special offensive abilities. They also have a way to try and keep rogues from becoming completely fucking useless:
Like we've said in previous updates, we want to allow player to experiment with multiple party compositions, including ones that might not conform to the tank + DPS format. One way this grid system supports that goal is evasion based defense and enemy disruption. Evasion based defense is the idea that I can attack with a character and then move that character in such a way that it makes it difficult for my enemy to effectively re-position themselves to mount a concentrated counterattack. Rogues are particularly good at this sort of hit and run tactic. Enemy disruption is similar, in that some classes are capable of throwing their enemies around the battlefield, disrupting their formation and making it difficult for them to effectively strike back in their following turn.
