Lately I started using lots of curses, which made me wonder how much do they actually drain? Answers like: "not much", "a lot", "okay ammount" didn't satisfy me as I still didn't know how much prayer potions would I need for a certain ammount of time. This led me to the conclusion: There should be a Prayer Drain calculator! Counting the time needed for a certain prayer to drain prayer to zero, doesn't sound that hard. By counting again with high prayer bonus as well, prayer drain could be made into a formula followed by a calculator. What I imagined: You could enter your prayer points Prayer bonus Select which prayer do you want to switch on Then the calculator would tell: the prayer points drain/minute count how much prayer potions/super restores/super prayer potions would you need for a certain ammount of time As I'm always in trouble with estimating the number of prayer pots I need for a certain task, I'd found this calculator most useful. Also the difference between prayers would be a lot more visible and could be used for various prayer related calculations. Even though in many situations players keep switching off prayers when it's not needed, this calculator could eliminiate "underpreparing" and serious "overpreparing". P.S.: This sort of potion calculator could be improved to contain even more potions (such as antifire, special restore or other boosting potions) and make it the ultimate potion setup calculator. Players would no longer need to search for the suggested setups, optimal at their level. They could just set when do they want to use a potion (for example you want to keep attack over x level) and set the ammount of time. P.S.2: This is a rough idea, in need of lots of polishing, opinions and eventually volunteers who would count the drain and someone capable of turning the data into a working calculator.
