-- Magic for the magic god, I guess.
--[[
Magic is, in the Drow Underdark mod, a bit different from what you'd be used to.
As usual, there are experience points and levels. These are kept track of with this script (drow/magic.lua). The script gives all drow on the map a second soul; this is where the information is stored. A reaction is used to start a drow on his or her journey through magic; this reaction assigns the drow a particular school.
Yes, schools. Schools are probably a familiar concept to you; however, the schools in Drow Underdark are not like many other schools.
First, you have divine magic. This is magic that uses the favor of the gods to work. This appears entirely in the form of reactions and won't be covered here; it'll use the "Priest" skill, a renamed strand extractor skill. Lolth will be the primary goddess prayed to.
Second, you have body magic, which has two sub-schools: destructive body magic and constructive body magic. Destructive body magic is such things as slowing down the opponent, decreasing his, her or its physical attributes, causing nausea, and, at higher levels, outright draining all of their blood. Constructive body magic is the healing of wounds, buffing of abilities, speeding up, the perfect inverse of destructive body magic. You want your healers to be constructive body mages.
Third, you have soul magic, which has the same two sub-schools. Changing mental attributes, skill rolls and, at higher levels, the skills themselves permenantly.
Fourth, you have sorcery. This is things like fire magic (drow don't really care for the above-ground, so burning it all down is just fine by them), paralysis, shooting webs, and other such generic things.
All of these things start out weak, but grow very strong over time. A long time. Unlike battle, magic is learned not by experience, but by study; Drow will study in their free time, gaining experience points while idle. You may notice a bit of slowdown every once in a while; this is an unavoidable consequence. I'll try to make it as fast as possible.
