The Havoc Hex

From Rogschard's wiki

Story

The magic computer virus / spell that started The Replication. To this very day, traces of the Havoc Hex still lie dormant, waiting to infect any piece of technology it comes across. In the early stages of the Replication it spread through the internet, but as it grew, it became more powerful, more versatile, stranger... Its modern permutations can be spread through thought alone, cause explosive magic cascades, and even bring new life into existence.
