New Worlders
“Oi oi. Magic is not a thing that you can learn in a day or two, Firstly it seems that a guy that does not have a connection to the world can’t do it, and those guys have latent geniuses hidden inside them. “It’s something different. Mah, if it is a magic caster better than me he may be able to understand something. The highest magic casters are able to detect their opponent’s magic ability better.” “. . . . . .What does that mean?” “Ah, we magic casters have something like a magic aura made by our magic power, and it surrounds our body. The better one becomes at magic, the ability to sense it also increases. That and controlling the amount of magic power.” “. . . . . . Heh” Restraining his deepening voice, Momon replied with a not suspicious normal voice. It seemed that Momon did not have that ability. He could not feel anything of the sort from Ninya. No, was it possible to even feel it? “Afterwards? Mah, you cannot proceed without a teacher, but afterwards you should carve a contracted medium.” “A contracted medium?” “Eh. A special medium which you have contracted with, and engraved with special magic equations. You can use the magic from the your force of will.” “Is Ninya holding one?” “Eh. Mine is a grimoire.” He pointed at the bag he was carrying. “. . . . . .Can that grimoire be used by anyone?” “Ahaha. It’s impossible, Momon-san. The person that can extract power from the medium, is only the one who has formed a contract. And so Momon-san holding my grimoire cannot use it.” “Is that so, a pity.” Momon resisted the desire to click his tongue. “Mah, there are many people that steal the magic inside the medium though.” “Is that so?” “Eh.” “. . . . . . If that is the case then I have no choice but to steal magic?” “That is not true.” Ninya replied to Momon’s dangerous words with a smile on his face. “You can buy scrolls with magic inside the Guild. And you can use them to transfer mediums. And if you search, you can find adventurers that would sell them at reasonable prices. Occasionally, adventurers have a chance of holding onto rare or recently made magic rather than the Guild.” “—-How many spells one can inscribe depends on one’s magical ability. I can use 35 spells. I have learnt 20 from my master and have bought 15 others.”
 * 1) Karma Rating affects decision making
 * 2) Can learn magic that didn't exist in YGGDRASIL
 * 3) Don't count as "Players" for YGGDRASIL abilities and resurrection magic
 * 4) Can do things even if they do not have the class for it
 * 5) New Worlders have level limits
 * 6) Classes that require a certain level can be acquired at lower levels but unknown if other requirements still needed
 * 7) Bloodline is linked to level cap?
 * 1) Ignoring Bloodline, the chance of being strong for humans has very low percentages.
 * 2) Armor penalties for New Worlders?
 * 3) New Worlders learn magic differently Web Novel Chapter 21: “Yes. I want to become like Ninya-san and use magic.”

Conclusions
New Worlders seemed to be flagged as non-Players by Tier Magic and YGGDRASIL game systems due to the ash mechanic. The fact they do not count for PKing supports this.
