Grenade

Grenades are the weakest type of explosive and only damage enemies and players (not tiles) when thrown. They are purchased from the Demolitionist for each, or found rarely in chests. Once Hardmode is activated, they can be found in Pots (replacing Shurikens).

A thrown grenade will bounce slightly and roll until it either hits a valid target or 3 seconds have elapsed, after which it will explode.

Tips

 * Grenades are extremely useful early-game, dealing massive damage for such an easy weapon to acquire.
 * As Grenades do splash damage, it can be useful against Brain of Cthulhu first phase.
 * A single grenade is enough to one-shot a Bone Serpent, and sometimes, a World Feeder.
 * Grenades are handy against large numbers of enemies. A strategy to adapt during Blood Moons is to block off the doors and wait for the Zombies to accumulate. Once dawn has arrived and they are about to retreat, toss a grenade into them. This will reap a considerable amount of money with little effort.
 * Grenades can also be effective against the Devourer and the Eater of Worlds.
 * 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 anticipated.
 * Because of their ability to do damage to many enemies at once, grenades can also be useful against the Goblin Army.

Trivia

 * The sprite is very similar to the american M67 grenade, a grenade produced from 1968 to the present.
