[@Rekaigan] - I am not entirely sure either, but this is how I see it. Certain situations in the RP will be considered as obstacles - be it a stone wall that needs to be scaled or a scaled dragon that needs to be killed. And every obstacle will have a difficulty associated to it. As a player, you will not be aware of the actual difficulty number. But from my description, you will know how difficult it might be for your character. Then you respond by saying "Tamara decided that the best way to climb the wall is to use a Complex Levitation Spell. She makes the astral sign for Air and prepares to weave the Spell." You leave it there. Based on your character's stats and skills, and a die throw (which I will set up as a campaign here in roleplayerguild), I will determine whether she was successful in casting the spell. If she is, then you are allowed to continue in the next post by actually describing the effects of the spell and how she gets past the wall. You will react based on the situation I set up, and I will react based on the actions you 'intend' to take.

So, long story short, you are perfectly right in your assumption.
