The fir bough survival torch is made from 1 branch, 2 string, and 1 fir bough. Once it's burnt out, 1 of the string that was used is returned to the player (and dropped if there's no inventory space) 3 vertical tiles, it looks like the fir bough has been strapped to the branch that's used as a handle.
The tree bark survival torch is made from 2 branches, 3 tree bark, and 2 string. Same burn-out as the fir bough survival torch. 2 vertical tiles, it looks like a bundle of bark attached to a branch, attached to another branch that's used as a handle.
Quality is determined by the average of all the components + survival skill.
