Rarely will you happen upon the monsters by accident, so I'd hope you wouldn't go looking for trouble then be afraid when you find it. Also it never is just the small arms and artillery, is it? Because those need bullets and you can only use each of those once. A constant need of resupply, resupply, resupply. If you take good care of your spear it will last you much longer and kill many more things before you need to ask for help again. I suggest you use the quiet time wisely to practice with what I've already provided.

...Unless it's something other than monsters that you're hunting?
