[Notice] Beginner's Guide to the Hollows: Keep an eye on your Ether aptitude
According to a poll of Inter-Knot users, 76% of Hollow Raiders and 26% of Proxies enter and exit the Hollows at least once a week. The Hollows are full of unknown mysteries and riches. Still, before embracing the Hollows, you should pay close attention to your adaptability to Ether, which determines how long you can stay in the Hollows.

According to the official Ether Aptitude Indicator Test (Aptitude Scale 0-100), Inter-Knot suggests the following:
1) For those with scores of 50 or less (commonly referred to as "individuals non-adaptable to Ether"), off-site Proxy work may be a good option. While official agencies forbid approaching Hollows entirely, Inter-Knot does not govern so broadly. Wearing anti-corruption gear, taking anti-corruption medication, or putting together a dedicated medical team, can all increase your chances of survival within a Hollow.
2) For those with a score above 50 (commonly referred to as having an "aptitude for Ether"), congratulations on your Hollow-friendly aptitude! We still suggest all newcomers observe the "Recommended Hollow time" provided by the White Star Institute, and with practice, we believe you will conclude your own safe time.
3) Ether aptitude tends to plateau during adulthood. However, illness, aging, and psychological state can affect it to some extent. Please conduct regular self-testing to conclude your own safe time within the Hollows.

New Eridu offers newborns physical examinations and regular exams during adolescence, including Ether aptitude tests. But it's not very informative since as people grow their adaptability to Ether will change.

Indeed. Regular self-testing is important. You can go to a medical supply store or Hollow specialty store to buy Ether aptitude tests. If you're worried, buy a few and re-do the test~

If one has a high test score and outstanding Proxy skills, can they be a Proxy and a Hollow Raider at the same time? I'll guide myself in the Hollows, hahaha

People like that exist, but trust me, you don't want to deal with them. It's really hard to communicate...
