Traps

There are many types of traps you can make in terraria, for NPCs and players alike. Listed are common traps.

•lava trap

Made by pouring a bucket of lava into a long trench giving a thin layer of lava coating the bottom of the trench. Useful as it does not destroy anything the NPC/player dropped.

•sand trap

Made by placing a wall the dropping sand on top of it, then when the thing you want to destroy is underneath, break the wall and let the sand fall ontop of them.

•spike trap

Made from spikes found in dungeons. just place them on the ground or cover the spawn point in them. They are more effective when you double (or even triple) layer them as players with high tier armour and hammers can easily remove the spikes before the spikes kill them. The spike trap only works on multiplayer.
