Zot Defence
Zot Defence is a tower-defense-styled variation on Dungeon Crawl. You begin on Zot:5; monsters are generated in waves, swarming in from the upstairs. You must prevent the monsters from reaching the Orb of Zot, which you may not pick up or apport.
During each turn in which a hostile monster stands over the Orb, you suffer one point of rot damage. Each time you go up one experience level, you receive a new special "Zot Ability" which will aid you in protecting the Orb; the use of these abilities expends Zot Points, which are gained concurrently with experience.
The waves of monsters grow in strength over time; at the end of each wave, an out-of-depth "boss" monster is generated. Every few waves, a rune is generated on the stairs along with the boss monster. You may pick up the Orb, and leave the dungeon with it, if you are carrying fifteen runes.
