Is there a way to have two active spells in fable 2 like in fable 3

I'll do you one better.

Rent levels do not effect your morality over time.

Instead you get dinged initially (when you set it), but when you change it back you can get that morality back. When I tested it, I initially set my properties to high (as I needed money at the beginning) but once I owned all of Albion I pushed it back to low; and my morality came back.

Now I can't be sure it was in equal amounts but it was more than enough to get me over 100% long before the end.

To just give them the gold, no there is not, but if you go into the options, there is a place where you can slide how much money and/or experience the other player receives (as a percentage). So you would be helping them make gold and not earn any yourself, or very little.

If the slider is set so that one player gets all the gold, anything bought and sold will have all the money go to that player as well, so the income is not just limited to kills.
