Identify Mammon, his movement interval and the difference between server implementations.
In aCis 409 Interlude, BOM changes location every 30 minutes. MOM uses the same interval. The script excludes the current location when selecting the next Mammon destination. This differs from the 60-minute Mobius default: without knowing the player's server, do not promise one universal timer.
BOM means Blacksmith of Mammon (31126); MOM means Merchant of Mammon (31113). Mobius schedules a new random location every 60 minutes by default. Its spawn rows select the one-hour fallback. A draw can select the previous location again; this is not a guaranteed move to another dungeon.
Blacksmith of Mammon uses six Catacombs; Merchant of Mammon uses eight Necropolises. Availability also depends on the Seven Signs period, winning cabal and ownership of Gnosis for the Blacksmith or Avarice for the Merchant. A map marker identifies a possible spawn, not his current location.
