◆ stringbuffer_append_spelldesc()

static void stringbuffer_append_spelldesc ( StringBuffer sb,
const object spell 
)
static

Append a terse description of the spell's name, level, discipline, and paths to a stringbuffer. What comes out is something like: "medium fireball (a third level pyromancy) (paths: Fire)" this is used in both spellbook_type_describe() to generate the one-line description for a spellbook, and in spellbook_type_apply to summarize what the spellbook contains if you don't ID it until you start reading it.

Parameters
sbThe StringBuffer to append to
spellThe spell to describe
