Tutorials/Defense

Considering the upcoming Adventure Update and the introduction of new creatures, there's a good chance that your base will need defense structures more advanced than just a cobblestone wall. Thus, I propose:

1. All tutorials or mechanisms of defense are brought here.

2. Said articles are organized into chapters, ex.      1. Passive Defenses a. Materially Inexpensive i. Creepers ii. Zombies etc.        b. Materially Expensive 2. Active Defenses etc. 3. Add more defense mechanisms as the game updates or the mind wanders.

By doing this, we can centralize the defenses and make it easier for all players, particularly those new to the game. It will also make updates more manageable as we don't have to scramble all around the wiki.

Spiders
Simply place a 'lip' over any wall to prevent spiders scaling it, as shown schematically below
