2 Abreast

2 Abreast formation. A good general formation.

2 Deep

2 deep, a simple formation useful for wider areas.

3 Abreast

3 abreast, more a square with the leader in the front. Quite compact.

Circle

The circle formation looks pretty good, and provides a "wall" of cohorts around the leader.

Line

Line formation is best for small parties wanting to be in a single rank.

None

No formation! This is what NWN uses by default, but of course formations would allow the distances used to be different. A adequate formation and necessary in some circumstances.

Single File

Single file, also useful for small parties who want to order a party behind the leader in corridors ready for battle.

Staggered

Staggered is a rank formation which spreads the party out (from large area-affecting spells) or for other reasons (defending large amounts of ground).

Vee

The "V" formation allows a leader to order a large group in a defensive posture for advancing.

Wedge

The Wedge formation is useful for assaults due to the following of a single entity (for instance, going through a small gap in an enemies defences) and still providing protection for each member.
