Holy Hand Grenade

The Holy Hand Grenade is a thrown explosive that is an upgraded version of Dynamite, with more range and double the explosive radius (about 15 tiles).

Like Dynamite, it destroys blocks, with the exception of Dungeon Bricks, Lihzahrd Bricks, Cobalt, Palladium, Mythril, Orichalcum, Adamantite, Titanium, Hellstone (before defeating Wall of Flesh), Demon Altars, and any type of Chest (including Barrels and Trash Cans) if it has an item in it.
