Reward people you follow and interact with on Twitter with D&D style attribute points. Level up, maybe go on a quest. Who knows?
Simply send replies as you normally would, at-mention @socialdungeon and tell him what stat to award and how much.
The more you play, the higher your level, which comes in handy when going on text based adventures, which are launching soon. Create a questing group and storm the castle, defeat the Dark Lord and save the world. If you can.
