Huh, I thought mafia already had that, but turns out I just wrote a custom combo box deed a long time ago:
Code:
$CUSTOM|Combo|Fortune teller|_clanFortuneBuffUsed|$ITEM|+5 lbs|false|fortune buff familiar|$ITEM|+50% booze/food/item|false|fortune buff item|$ITEM|+50% gear/+100% meat|false|fortune buff meat|$ITEM|+100% mus/+50% hp|false|fortune buff mus|$ITEM|+100% mys/+50% mp|false|fortune buff mys|$ITEM|+100% mox/+50% init|false|fortune buff mox
There is no GUI to add this, though, so must be added manually like this:
Close down mafia and edit the file GLOBAL_prefs.txt in settings/
Make a backup copy first! Also make sure your editor isn't set to word wrap.
Find the line that starts with dailyDeedsOptions= and add a comma and the custom deed to the end of the line. You can reorder the lines easily in mafia, once you restart it.
