Spikes
Use the 
Wooden Spike,
the 
Stone Spike or 
Reinforced Stone Spike to damage enemies on
contact. Higher tiers have more health and deal more damage, while keeping the same attack rate,
reach and knockback.
Mechanics
Section titled “Mechanics”Spikes attack 2 times per second, damaging enemy
players, 
zombies and structures. They also push players and
zombies away. They spare you, your group members and structures owned
by any of you, except 
TNT. Players with 
Spawn protection
take no damage or knockback.
Spikes do not damage resources or gifts. They cannot hit the 
Reaper
or 
Landmine. You can have 16 spikes placed at a time,
with all tiers sharing your building limit.
