On p. 295 of Gaia, the rules state that Natura+20 is the maximum degree by which a person can exceed his base racial Natura. Using the table on that same page, in which human/Nephilim Natura is listed as 0, that seems to suggest that basically any PC or NPC is limited to a Gnosis of 20. This really doesn't seem to work for a couple of reasons. 1st, it renders all the spells above level 80 useless, since one has to have a Gnosis of at least 25 to cast high magic and 40 to cast divine magic. Obviously, only exceptionally high level characters should be capable of that sort of magic, but it seems to me that the basic premise and a lot of the fun of Anima is that they are capable of it. 2nd, for instance, while maybe Eljared isn't human, using the table I mentioned before it doesn't seem as though there is any way that she would have a Gnosis that makes sense of the power that she is portrayed as having. 20 just doesn't seem to work considering the way in which she is described as interacting with a lot of other characters, organizations, and powers.
I'm really considering starting up a game as GM, and I've spent a good bit of time working up some characters of various power levels just to get a feel for the interaction of the setting and the mechanics of the game, and this problem reflects a larger trend of the rules and fluff not quite working out to me. I know I could homerule a couple of things, but I hate to start out by immediately changing things around. Not necessarily looking for advice, but would love to hear thoughts and how everyone has worked it out in their own games. Thanks!
