Friction Fire ideas

[Schrodingers Box]

I’d like to see the ability to do friction fires given the limited matches on interloper. The trade off would be it could take an exceptionally long time- especially with low fire skills so presumable an unprepared player would die trying to start the fire in inclement weather so there is no “free fire” to get out of trouble. Also starting the fire would greatly fatigue the player and use food and water at a faster rate. It just seems that all other resources are in some way ultimately renewable if only through beachcoming so survival could be indefinite, but relying only on a mag lens at some point very late interloper seems limiting.
