I decided to calculate how long does it take to advance Magic Level with my Ranger, since ML 11 takes forever to come...
Now it's time to share the information :)
I'm still ML 7, so it will take me some time to confirm the rest of the road towards ML 11, but I'll keep this topic updated!

This is only for Rangers and Warriors. To let these numbers 100% accurate, consider that you cast any spell to train and recover your mana points with mana ampoules. You will need to use X mana ampoules to advance magic level.


Useful Information by Zio Joe:
The trend seems to be 1.9 times the last amount.
= 180~190% more mana spent per magic level advancement.

9-10 about 9,8k amps.

Surely your numbers arent accurate cuz mana amps mana given jumping a little. But its Almost clear that the req for the next lvl is around ( previous mana needed for advance *1.8 - 1,9)

P.s you say its forever. It will be almost 20k amps from 10 to 11. So from 0 to 11 is around 35k mana amps.
I know I shouldnt compare that but just saying that for me its around 160k mana ampules to advance from 70 to 71.

With 160k mana amps you would make it like 0-13,3 m lvl on ranger!

First of all there is big bug. Each mana ampoule gives 50-75 mana points. So you should count ammount of used spells. Then you can find mana needed to adavance for each magic level.

@Devilish, in a long run you are getting quite accurate amount , so..

Yeah but still it will be less / more than 62.5 (avg). Maybe 59.7, maybe 63.3. Nobody knows.

after 100amps it might be avg 60-65.
after 1000 it might be 62-63
after 100000 it will surely be in the interval of 62-63. with the probability of 99%+

note: its only if given mana is totaly random in the interval of 50-75.

I simply looked right when 1% was changed in my magic level, so I started to count the mana ampoules used for the next magic level. In case of ML 7 to 8, it was 27 mana ampoules. So I did the same thing for the other 1%, counted 27 mana ampoules and 1% was reduced towards the next magic level(8). So I guess these numbers are pretty much accurate, it's pretty useful information already, even if only 99% accurate, not 100%. who cares?

I'm not gonna sit here all day long calculating exact mana points used by every single spell casted to be 1000000000% correct with the calcs, sorry I ain't that nerdy and got better stuff to do!
You guys can feel free to do that tho ^^

I did some testing and I think I got it down to within a few mana points...

So I just watched the ML as I cast spells, and here's what I found.

0-1 2000
1-2 ~3800
2-3 ~7200
3-4 ~13700
4-5 ~26000

The trend seems to be 1.9 times the last amount. I am currently in the middle of 4-5, but each percentage takes between 255-260 mana to go up, and when I extrapolated, it worked out according to 1.9 times within about 60mana total. Not sure what the mana ampoules would work out to, but maybe someone can check if the numbers work out. This is assuming that the levels increase linearly.

5-11 (660k +/- on vials at elsa)
