Yep! Evergreen always wins!! XD Fog and arboreal monsters are my favorite!

I love going deep into the rules :D

That's a really good tip! I guess one roll per day will slow down too much, maybe every 3 hours (circa 3 per day) could be a good compromise

The players may take up to a -6 on navigation or survival. Each -2 grants a +1 to the other roll. This represents the characters decision to take a more direct or cautious route.

I recommend successes move them to safer columns and failures move them to more dangerous columns. That is, if they are in a "dangerous area" a success keeps them there, a good success moves them to "slightly dangerous" and a failure moves them to "very dangerous."

This is a great idea too, especially the -2/+1 mechanic. Using both navigation and survival is a great way to determine encounters! Really good point! Will be funny creating a monsters related chart.
I presume a table divided in 4 or 5 difficulty zones. Every part has 3 or 4 levels. To pass from one difficulty zone to the other, the PCs have to acquire X successes, where X are the difficulty zone's levels. Successes lead them to lower encounters difficulties, failures, to harder ones. Could work!

I suppose it is a home rules. And sounds way better than the hiking skill from basic. Good one!

(I always love it when players go looking for those skills they ought to have bought and that I put on the "most people have them" list at the campaign start)

Totally agree. Too often i don't remember to use "utility skills". In this way they have to know navigation, survival and hiking at least, and for a group of adventurers should be mandatory.

Thank you very much, a lot of materials to working on!

At this point, instead to use individual maps, i can set a X successes on navigation, and at that point an important fight happens, or a crossway between "ancient ruin-left, deep forest-right".
By the way, what "figgies" are?

That's very stressfull, i like it XD

Yep, venomous fungi and "poisonous clouds" are always funny. An FP reletated venom with linked affliction is a good plane! My PCs will love it(question mark? :D)
