[QUOTE="osarusan, post: 2266525, member: 13950"] Yes, (0,0) is a point. Basically, I'm trying to make a table of costs for mana points in an XP-based point-buy system. The cost to buy a mana point increases depending on the number of mana points that you have, so when you only have a few mana, you don't spend as much XP to buy the next mana point as you would if you had many many. It's based off of a point-buy system where Wizards could buy their spell slots with XP points, thus customizing how many slots they had. I'm converting that system over to the Elements of Magic system, and converting slots into MP is where I've hit the snag. (I really hope this makes sense... it's hard to know if I've explained that sufficiently, so please tell me if I need to clarify it more.) For what I've calculated (from the two books I mentioned above which I am using to make this list), (x,y) x= the total number of mana points purchased, and y= the cost to buy 1 mana point at that level: Therefore, when you want to have up to 0 mana points, you spend 0 XP. When you want to have up to 5 mana points, you spend 15.2 on each one. When you want to have between 56 and 68 mana points, you would be spending 76.7 XP on each one. That progression is very jumpy and I'm looking for a simpler way to express it. (I know that the points are not good enough to make a decent curve. It will have to be simplified or smoothed into a decent-looking progression.) I used Excell to plot the numbers, but basically that's all I know how to do in Excell. I know it probably the program I need to be using, but I'm not sure how to do it. I hope this all makes sense... I'm trying to explain this at 2 am. ;-) One last run through: I'm making a conversion of Elements of Magic's mana-point casting system into the Buy The Numbers XP-based point-buy character creation/levelling system. I got these numbers by calculating the XP a BtM Wizard spends on his spell slots at each level and equating it to the amount of Mana Points an EoM Wizard would have at the same level (since these variant Wizards are roughly equal in power to eachother). What I want to do with these numbers now is figure out a general XP-cost progression for each mana point so the characters can buy as little or as many mana points with their available XP as they want. What I've got so far would look like this: 1st mana point costs: 15 XP 2nd mana point costs: 15 XP 3rd mana point costs: 15 XP 4th mana point costs: 15 XP 5th mana point costs: 15 XP 6th mana point costs: 12 XP (weird little jump in the graph here, I know) 7th mana point costs: 12 XP . . . 242nd mana point costs: 125 XP 243rd mana point costs: 125 XP 244th mana point costs: 125 XP but I'd like to have something that looks more like this: 1st mana point costs: 10 2nd mana point costs: 11 3rd mana point costs: 12 4th mana point costs: 14 5th mana point costs: 17 ...and so on. The problem is that it needs to roughly follow the plot of points that I've listed in order to maintain game balance. I hope this makes better sense. Sorry to ask such a confusing problem... :-S [/QUOTE]
