Hello.
While I understand that Realms of Terrinoth is first and foremost a setting book, and only secondarily a source of additional rules, I am nonetheless a tad confused by the rule set for Verse and Rune Magic. From what I can gather, the two skills do exactly the same that Arcana does , in terms of 1) access to magic categories (attack, dispel, etc) and 2) gaining access to it (certain careers have it a a career skill), with a detriment (needing a Rune or a musical Instrument) that is 1) not balanced by any advantage and 2) easily ignored once the characters have their own item.
I was wondering why, then, the system provides us with a different skill than simply saying that Arcana can be channeled in different ways, including singing or through the use of a Rune, depending on the caster.
i really feel like I am missing some details, albeit small, that makes the three approaches to magic different beside the narrative difference.
any help would be appreciated.
