More lenient soft stamina combat, decentralized gun inaccuracy from combat mode. (#12347)

* A more lenient soft stamina crit.

* Yea, your shots are gonna go straight toh.

* accuracy whacks (leaves the bow as is for now).

* Fixing stam penalties calculations, spread the range.

* aaaaaah

* 1.4 seconds delay vs 1.2

* Thanks, linter.

* Missed one.
