The Spear is a ranged weapon in Devast.io and likely the first one crafted in a game. The spear does 80 damage, but requires a charge-up of around 2 seconds before it fires. It also has a slow velocity and range, and leaves your inventory when thrown, requiring you to pick it up from wherever it lands.
The spear can also be used to damage furniture in abandoned houses for resources fast, as in early game you generally will not have a better weapon to break things with.
Good for: Normal Ghouls, Fast Ghouls, Explosive Ghouls, and Noob players. Bad for: Armored Ghouls, smart players, and players inside full walls.
Strategy against: Try to dodge, and after the spear lands(even if it hits you) pick it up so the enemy can't.
If you want to use the spear to kill, you will usually need more than one spear. It takes 4 spear hits to kill someone, but you are not going to hit every single one, and the enemy can pick up thrown spears. You can also finish the player off with melee if you land 3 spear hits, since they will only have 15 health remaining.
