Iron spears are weirdly missing as an option when smithing and were rather simple to add in.
They're crafted in the same manner as other metal spears and have stats that are in line with the rest of progression.
First time doing something like this, so let me know if there's any issues. Also feel free to tweak/repost it as you see fit (only has en lang, for instance).
This likely conflicts with any other mod that changes spears.
