Spike

Spikes are a type of block trap that simply harm the player when they come into contact with it. They are the most common type of block trap. On harder planets, they do more damage. On ERROR planets, they are guaranteed to be piercing, which is really bad because on ERROR planets, the Charm Of Pierce Defence is non-functional. On non-ERROR planets, they can be piercing, other than Harmless and Mostly Harmless planets. Planets more difficult than that have a higher chance of piercing the higher the difficulty is.
