Remove the buffs. Give something else more 'generic' with less repercussion.

Maybe like different houses will "give out" X no. of pots as a bonus lol. Create a pot machine for different house, b4 we leave the house to explore the wilderness to kill mobs, activate it to produce pots. Go in after certain timeframe to collect free pots.

Oh Wait, this sounds so Farmville lol...but i rather this than power/loot/mana/watever buffs
