Your best bet would be to add a player.pl file to your starter zones or use the new global player.pl file. You would just use the enter zone sub event and check if they are level 1 (or anything less than 50) and then set them to level 50 using a quest command. It would be something like this:
Code:
sub EVENT_ENTERZONE {
if ($ulevel < 50)
{
quest::level(50);
}
}
There is no real DB setting for doing what you are wanting.
