Other ranges in feet 

see note 4 

1. Spells with a range of 0 feet generally involve placing some kind of sigil, glyph, or sign on something else. Such spells effectively have a range of touch but you cannot "hold the charge" as you can with a touch spell. 
2. Range rounded down to the nearest 10th kilometer. 
3. The exact number of squares these spells can reach seldom proves significant. 
4. When a spell has a range in feet that is not listed here, simply divide the range in feet by 5 to get the number of squares it reaches. To determine the range in meters, multiply the range in squares by 2.
