toku49: I just started playing Arena. what is the max level? Couldn't find any info after a search.
BalrogMagog: I know this post is old, but I figured I would add what I have found. I'm using a saved game editor (arenaed) to see if there is a level cap. I plotted the EXP tables on a spreadsheet and took them out to lvl 50, just too see what would look like. The formula listed above (1.5x previous EXP level above Lvl 10) breaks down beyond Lvl 26 for a battlemage. I haven't tried the other class types yet. Going from Lvl 26 to a theoretical Lvl 27 caused me to jump to Lvl 38.
Lvl 01: 0
Lvl 02: 1,200
Lvl 03: 2,250
Lvl 04: 4,218
Lvl 05: 7,910
Lvl 06: 14,831
Lvl 07: 27,809
Lvl 08: 52,142
Lvl 09: 97,766
Lvl 10: 183,312
Lvl 11: 274,968
Lvl 12: 412,452
Lvl 13: 618,678
Lvl 14: 928,017
Lvl 15: 1,392,026
Lvl 16: 2,088,038
Lvl 17: 3,132,057
Lvl 18: 4,698,086
Lvl 19: 7,047,129
Lvl 20: 10,570,694
Lvl 21: 15,856,040
Lvl 22: 23,784,061
Lvl 23: 35,676,091
Lvl 24: 53,514,137
Lvl 25: 80,271,205
Lvl 26: 120,406,807
????????????????
Lvl 38: 180,610,211
The 12 skipped levels calculate out to an average of 5,016,950.3333 each, but I haven't been able to level up beyond 38 just by tweaking EXP.
It appears that earning EXP at a point at or above the target level does not trigger a retroactive level up. You have to earn the EXP that pushes you into the next level. I've tried a number of EXP point spots above 180,610,211, but I have not been able to find the trigger that will allow me to level beyond 38. If I recall, I had this problem 20 years ago when I was playing with a different save game editor (arenaedt). I couldn't get beyond 38 as a battlemage.
Based on what I have collected so far, there appears to be a hard cap at 38. I've tried numerous calculated level up points, even up into the bilions, but I have not been able to trigger a level up beyond 38.
XP requirements, as I have said, scale by a factor of 1.5 for each level past 10. To reach level 38 should, in theory, require just over 85222 times as much XP as reaching level 10; it's worth noting that this value does not fit in a 16-bit integer. Perhaps the game gets confused at this point?
With that said, the game does not appear to truncate the value in the middle of the calculation; I calculated the ratio between level 10 and 26 XP by the 1.5 rule and by dividing the XXP totals you posted, and the results agreed to 5 decimal places.
Also, reaching level 38 ought to require 5,005,216,975 XP, which is too large to fit into a 32-bit integer (710,249,679 is the value that would be stored here); this is right past when an overflow would occur. Maybe faster leveling classes can gain one more level?
I suggest trying this with a Thief, which is the fastest leveling class, and see if you get similar results. (It's clear that there is some bug here that a typical player would not ordinarily encounter.)
