Mushroom Spear is the best in the game.

The Mushroom Spear is a Spear that can be purchased for 70 in PC and 30 in console/ mobile.60 damage and 72 in mobile are inflicted by it.It can damage mobs through solid blocks.When used, it leaves a trail of mushrooms.As with all Spears, the best Prefix for this weapon is Godly.

If you don't have good armor yet, it's advisable to get this weapon as quickly as possible, as it is one of the best early-Hardmode weapons.It is possible to make your own surface biome by planting Mushroom Grass seeds on a two or three block thick layer of Mud.

The spear does not pierce through solid blocks when hitting non-solid mobs like the Man Eater, as can be seen when attempting to strike mobs through walls.The mushroom trail left behind by the spear-tip causes the damage that pierces through walls.

It has a variety of uses due to the trail it leaves behind, which damages mobs for about half of its own damage in addition to its normal piercing attack.Each mushroom only exists for a brief period of time, but their timeout appears to be unaffected by dealing damage.They cause no knockback, so a mob can run into them and be dealt a lot of damage.It seems to be an ideal weapon for dealing with bosses, such as The Destroyer and The Twins.It is possible to spread the mushroom trail out like a wall of damage by jumping and attacking at the same time.The trail will deal massive damage to anything that's chasing you if you fire backwards while running.

It can be used on a Blood Moon or Solar Eclipse event at the beginning of Hard Mode, when the player is yet to obtain higher-tier armor.It is possible to remain within one's house and still grab a significant amount of loot from monsters as they assault the home using this weapon.Nothing can enter the home if precautions are taken.It can be difficult to fight in cramped spaces with the mushroom trail being very useful.

If you want to fight hordes of monsters who can't attack through walls, you can wall yourself in completely and stab through the walls.This can make it possible to survive a Pirate Invasion as well as fight strong monsters with non-penetrating attacks.An Ice Golem is boring.

Another use for the spear is to look through walls at short range as the mushroom trail illuminates its immediate surroundings, making it possible to see ores and caves you normally couldn't see without a Spelunker Potion or other means of illumination.If Spelunker Potions are in limited supply, this can be a way to save them.
