This is not an easy journey and 9 out 10 will die in the process.

While I understand the sentiment, as one of film's most famous heroes has said, [url=https://youtu.be/gRvu0yHoHy8?t=61]never tell me the odds[/url]. Unless the journey is literally Russian Roulette, precise odds are meaningless. More powerful beings will obviously have better odds that weaker beings. We'd rather know [i]why[/i] the journey is dangerous or otherwise difficult.

A difficult journey also does not need to be fatal. It might just require an enormous expenditure of power to traverse (e.g. spaceflight) or it might be hard to find (e.g. a connection which is only sometimes open).

P.S. This isn't a critical flaw in your sheet. I just thought I'd bring it up.
