No worries, Ichthys, that's what questions are for. ;) I just wasn't sure if the term was covering the particular powerhead(so not the term I want but pfffft it means what I need it to) of an area or the space that power was responsible for. Now I know. Confusion gone. 

Heh. Good points, Schradinger. Also, just paid attention to your avatar. I do like.

EDIT: As spell is the go to now for the work done to cause anything to occur using magic... and you've mentioned there isn't really a type or the like, but that it is a process... Can more than one process of steps be compiled into a spell that will accomplish the same thing? Like... Fireball... oh how we like the fireballs. 

Could two people able to use magic, with the intent to make a fireball, having decided to use a spell to do so, create the same, or extremely similar summoned, burning fireshape effect by say, person A turning three times and clapping twice and thinking about fire, while person B shouts "FIRE!" and points somewhere? 

What dictates, or is presumed to dictate, the methods used in any specific spell? From divination to elemental control to raising the dead or moving a pot of water over someone's head and dumping it on them to stop a fistfight?
