Area of effect

From NWNWiki

Area of effect refers to both the shape and size of the region a spell occupies when it is triggered.

The shape of an area of effect may be one of the following.

Cylinder  
This is effectively a rectangle extending the specified distance in the direction the spell is aimed, with a width of 3 meters.
Spellcone 
The origin of the cone is the caster, with an angle of 60 degrees. The cone extends in the direction the spell was cast to the specified distance.
Sphere  
This has the specified radius, centered at the spell's target.

For spells that do not have a true "area" of effect, the type of target may be indicated by one of the following.

Caster  
Only the caster is affected. These spells usually do not need to be targeted.
Point  
The spell summons a creature at the targeted location.
Single  
Only the targeted object is affected.

The size of an area of effect may be one of the following. When just a size is given, the shape is assumed to be a sphere (hence the size indicates the radius).

Small 1.67 meters
Medium 3.33 meters
Large 5 meters
Huge 6.67 meters
Gargantuan 8.33 meters
Colossal 10 meters
