Now, I'm not sure if you were thinking like a bunch of your members were thinking (Mobs dropping 1 Tomestone of Philo each), but this would lead to horrific abuse of CM as a Mob Breeding Ground (and Griefing for people who turn off the Searchlights, like Griefing for people who kill Lambs).
CM infinitely spawns mobs until the searchlights are deactivated, at which point you can proceed w/o risk of suicidal death. If each mob is given 1 Tomestone of Philo (for each person), you could easily rack up 2,000 Philo at the entrance and leave.
