How is This Possible?

Cost of a lvl 12 Rune after averaging with 6 was 497M coins. It may be a little different for everyone but that was the average I got. I've spent a lot of time working out the math of this game.

then you didnt do that well in the rune temple, because with synergy you would have been cheaper. when i had the time i went rune temple instead of synergy, but now with 420 fragments and a lot more coins than i used to get and no 3rd sub i dont have to anymore. i went rune temple because my average costs in there always seemed lower than the actual synergy costs.
however for everyone who is too lazy (as i was until today) to do the math with synergy for yellow runes:

lv01 0 (base XP 750)
lv02 960
lv03 1920
lv04 3840
lv05 7680
lv06 15360
lv07 30720
lv08 61440
lv09 122880
lv10 245760
lv11 491520
lv12 983040 = 491,520,000

1 synergy for 600,000 = 1200 XP

@hudson: matts and my guesstimates where off by 8,480,000 ... 5.48m off according to your math. so i dont think we did as bad as you suggested we did
