Tired of harvesting scrap polymers? This 7 Days to Die mod allows you to craft scrap polymers. The new A18 (b152) now requires 2 scrap polymers to craft steel arrows and bolts (replacement for wood and feathers). Feathers are rare enough, but scrap polymer is worse to harvest. Sure: It should be balanced, so Claymore chose to go the way of real life chemistry (almost). 50 gas cans equals 1 scrap polymer in the chemistry station.
The forum topic of the mod is here.
