welcome.

also you may often get potentials from event drops (if and when they happen again)

and since the super pill is 100% it means you can use it at lvl 9 and jump to lvl 10 cause its a garanted +1. so its nice to save it for when you get to high and you're afraid you'll fail.

pills are starting to go on sale now lower and lower. if you are unable to afford them try waiting for drop events or save your super pill for "some day" or just use all 3. you probably already know this but since the fisrt 3 uses are 100% aniways it seem using a 100% pill on a 100% lvl is rather a waste.

for example;
lvl 1 = 100%
lvl 2 = 100%
lvl 3 = 100%
lvl 4 = 97%
lvl 5 = 85%
lvl 6 = 73
lvl 7 = 61
lvl 8 = 56
lvl 9 = 43
lvl 10 = 30
lvl 11 = 17
lvl 12 = 6

these are not accurate numbers but if gives you a genaral idea of how the higher you go the more fails you can get. i've known people who get +7 to +9 with no fails while some get to +4 and then fail back to 3 then up then down then up.. so its random luck.
