Greetings.

There was a long delay between this issue and issue 58. However, there will
probably be more frequent issues soon - we are taking on new staff. If you're
interested in being an editor, let me know soon.

I'm starting a tournament in a few days. Read the newsgroup for details.

Electric Head by Anton Marsden

Electric Head consists of 4 components:
- The Core Clear
- Mini HSA
- A small paper
- A modified version of Carbonite

These components combined with a nice PSpace routine are the key to the
success of this warrior. It has weaknesses but so does every warrior.
However, one of it's strengths is the ability to kill heavy imp/stones.
