I am trying to understand the third rank in the Parkour merit tree, "Wall Run" (Tribes Of The Moon -- Page 98)
First of all it is important to put the normal rules of climbing here first:
Climbing an object requires a number of successes in an instant or extended action. Your character can climb 10 feet with each success rolled. Objects that are 10 feet or less in height can be climbed as an instant action. Rolls may be modified based on the availability of hand- and footholds, sheerness or slipperiness of the slope, and wind conditions, all at the Storyteller's discretion. By the same token, if the character chooses to take his time and pick his way carefully up the incline, each minute added to the roll provides a +1 modifier, to a maximum of +3. Thus, if a character takes his time and each roll represents three minutes of effort instead of one, a +2 modifier is added to each roll.
And then also the Wall Run merit:
Wall Run -- Your character has mastered the quick wall-run and leaping climb techniques of parkour. When using Athletics to climb, your character is capable of scaling heights of 10 feet + five feet per dot in Athletics as an instant action (rather than the normal 10 feet), though every full 10 feet beyond the first imposes a -1 dice penalty.
There are two parts of this that I want clarification on:
your character is capable of scaling heights of 10 feet + five feet per dot in Athletics as an instant action (rather than the normal 10 feet)
Does this mean that if my character has say, 4 Athletics, he will scale 30 feet for each success rolled? If so, this means a character could scale 90 feet in one round with only 3 successes. This is way more than he could run or jump, and I feel I might be misunderstanding it.
though every full 10 feet beyond the first imposes a -1 dice penalty
This seems a bit confusing because normally I would think that when climbing say, the side of a building, you would roll each round to see how much you have climbed. But here it seems to say that I must first decide how far I want to climb in that round, and this distance gives me a penalty? So if I wanted to climb only 50 feet, and I had 4 Athletics, I would get -4 dice penalty. And say I had 2 successes, that means I could travel 60 feet? It seems a bit silly the ratio of this bonus/penalty.
Can someone clarify these rules please?
