Grenade

Grenades are the weakest type of explosives, and only damage mobs and players (not tiles) when thrown. They can only be bought from a demolitionist. They cost 4 silver each. Otherwise, they are rarely found in chests.

A thrown grenade will bounce a little and roll along the ground at a decreasing speed until it explodes. Grenades will explode when they hit a valid target or automatically after 3 seconds.

Like all explosives, Grenades still damage players while PvP is off, dealing 120 base damage.

Grenades are handy used against large numbers of enemies. A strategy to adapt during Blood Moons is to block off the doors, let the zombies gather, and when they begin to retreat at dawn throw a grenade at them, and they will be destroyed in a spectacular explosion. This will reap a considerable amount of money with little effort. They can also make an effective weapon against the Devourer and the Eater of Worlds.

Because Grenades automatically explode when they hit an enemy, using grenades as short-ranged weapons is a really bad idea, and generally results in an explosion close enough to you to damage you.

Using grenades against a caster AI enemy is especially inadvisable. The grenade can easily explode upon hitting one of the enemy's projectiles, often much closer to the player than would be expected.
