Spike

Spikes are blocks found in a Dungeon. They deal damage to the player on contact. Spikes seem to deal no damage to monsters. They can be collected by using a hammer and placed down for use as a PvP barricade, or also used to create elaborate decorations. A player that touches spikes experiences a knockback effect. The knockback effect is ignored if the player has a cobalt shield equipped. Spikes can also be destroyed using Dynamite, making them useful for clearing trapped spawns in multiplayer.
