I’ve mentioned this in a few other threads but decided to make a new one about it specifically.
It’s possible to climb any height with 0 stamina usage, without cheats or exploits.
Climbing Boots w/ Advanced Flexibility Kit
Climbing Gloves w/ Advanced Flexibility Kit
Any Light Armor w/ Advanced Flexibility Kit
Any Light Legs w/Advanced Flexibility Kit
Any Medium Helm w/ Advanced Flexibility Kit
No kit needed on light helms; you can also go without any headgear.
If you don’t have access to the climbing gear you can just use any light gloves/boots. You’ll use a very tiny amount of stamina and still be able to scale almost any height with ease - this is useful for climbing in the frozen north or volcano when you need more elemental protection than what climbing gear provides.
