[QUOTE="Michael Morris, post: 6266223, member: 87"] It's actually not that bad if you break it down into two steps. First, divide the rank by 5. That's the number of d12's. The remainder is the other die 1 - d4, 2 - d6, 3 - d8, 4 - d10. If the rank is a multiple of 5 then it's all d12's. No matter how many dice get cast, only the highest 2 count. Hence the while the odds of performing a difficult task go down, the target numbers never change. They are: 12 - Very Easy 15 - Easy 18 - Medium 21 - Hard 24 - Very Hard Very easy is made just over 50% of the time by the weakest of characters - rank 1 - someone rolling d20+d4 (1 average roll). Easy is mad just over 50% of the time by someone at rank 4 (d20+d10). Medium is made half the time at rank 6 (d20 + d12 + d4, 19.5 avg), hard is made just over half the time at rank 8 (d20+d12+d8, 21.5 avg) and very hard is made at rank 10 just under half the time (d20+2d12, 23.5 avg). Target number 24 is also significant in that it's the highest target number a rank 1 character can hit, though the odds of rolling 4 and 20 on d20+d4 are 1 in 80, so it's a long shot. Unless a character wants to have a lot of actions, the issue of diminishing returns comes up. Once you have 2d12 to roll on an action, the next five points you spend are probably more useful spent on other things. The next five after that are almost certainly better off elsewhere. The neat part of this is the game therefore doesn't need the complexity of changing the cost to purchase a power as it goes up. For example, in a lot of games the point cost of a skill is often the skill's current value. So, rank 1 costs 1, rank 2 costs 3, rank 3 costs 6. Eventually it becomes very expensive to increase a skill, encouraging the player to branch out. Prima is sneakier in this regard - the cost doesn't change, but the odds benefit (aside from extra actions) per point spent drops over time, even from the beginning. [/QUOTE]
