Granite mining is featuring a nice update today. There have been plans for adding banking to granite mining for a while now, but now it is possible thanks to the recent updates to the walking and banking code. So, expect the next update to support granite banking. If you do plan on granite banking, make sure you have waterskins, shantay pass and at least 1,000 gp in your bank.
The script will stop if you don't have coins in your bank for the carpet rides to the granite area. As for the waterskin and shantay pass, the bot will handle it ;)
