On the road
Whats the ruling / clarification in the rule book?
Magic-Users may learn spells by being taught by another
Magic-User, or by studying another Magic-User's
spellbook. If being taught, a spell can be learned in a
single day; researching another Magic-User's spellbook
takes one day per spell level. In either case, the spell
learned must be transcribed into the Magic-User's own
spellbook, at a cost of 500 gp per spell level transcribed.
Does that mean if two consenting Magic Users want to trade spells it would still cost each one 500 gp to trade a 1st level spell?
