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.

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.
