Updates:
Added embezzle skill function to needed attacks until target level. Since I couldn't do it other way, I added it as an separate list, but atleast you can compare it to no embezzle skill needed attacks.
Fixes:
Nothing important, just some small visual fixes.

Note: In google version, you have to insert dates, for example 02/21/2010 instead of 21/02/2010.
Also, this version might be buggy.

Updates:
Replaced power level thing with old-fashioned exp table sheet, it tells minimum exp at that level, exp needed until next level and base attack, HP and agility.
Fixes:
Attacks until target level with embezzle has now truly correct formula. It's impossible for exp gain to be any number with comma, so formula now rounds embezzle influenced exp gain (In some cases you indeed end up getting same amount of exp even with embezzle (Lvl 1 monsters never give you more exp than 5, no matter the level of embezzle. Lvl 2 monsters give you 7 exp with lvl 0-5 emb and 8 exp with lvl 6-10 emb)).
Future:
I have plan for much more compact "attacks till target level" calculator, where you just have to insert desired NPC's level to get the answer, however, for that, I am going to need exp gain formula from CK. So yeah, everything depends on him, whether or not he decides to give it to me. xD

Updates:
Added lvls 70, 110, 120, 130, 140 and 150 in attacks needed in LevelCalc.
Extended Exp table from lvl 200 to 250

Fixes:
None

Future:
Gonna need formula for Base Defence.
And I still need that damn formula for exp gain from NPC's.

I am currently working on a new updated FutureRP Help site

I should have it released in a few weeks, so I'll let you know.

Updates:
After many tries using Inception on CK and fails because my dead wife kept sabotaging my efforts, I finally managed to get the legendary formula for exp gain, meaning I was able to make table of attacks needed much more compact.
Don't let CK down! Don't ever use the formula for evil purposes!

Fixes:
None

Future:
Still don't have the Defence formula, but I won't give up!
Next time CK, next time...
