In the current preview, copper spears have the exact same jab damage and charge multiplier as a stone spear, but has a harsher cooldown time.
This leads to the copper spear being a strict downgrade to the stone spear in every way, when it's meant to be an in-between of stone and iron. It should be an in-between just like the other copper tools.
A simple change to 2.5 spear damage would remedy this issue and make the copper spear behave like every other copper item in the game.
