Spikes

Spikes are a type of building that is mostly used for defense. They are great at putting around your base to kill monsters(Spikes can't give you rewards of the monsters they kill meaning they can't auto farm, if you want to auto farm take a look at turrets) and injure/kill players, and generally keeping anybody out.

Requirements
Spikes cost 20 wood and stone a small but worth a dime for a low level. You can only place 20 at maximum at a time.

Usage
Spikes do 20 damage, around a fifth of a player's hp and around half of a mob's hp. So use them wisely. You can line your base with spikes to keep out monsters and players. However players can easily evade spikes by jumping over them. Monsters and players don't give any drops when you kill them with spikes. Spikes are easily spottable and avoidable and require the monster/player to touch them so place them around corners to startle or even injure/kill the player. Placement is key!
