So I have been meaning to do this test for a while (255 vs 200 cha) and finally decided to stop procrastinating. I jewelcrafted up some charisma gear (platinum/electrum star ruby stuff) and swapped in my Crude Stein instead of the Insignia Protector which enabled me to get 255 cha at the cost of about 150hp/30AC. I charmed and dispelled Gruplinort's PH until it broke charm and killed me (weaponized/hasted ilis wizards are no joke). Then I charmed the commander PH until it broke charm while I was clearing NG and killed me also. The biggest problem charming these guys wasn't the charm duration per se (I was quite surprised I could charm them for 2+ minutes at a time) it was their chain resisting stuns and mezzes. So I don't recommend charming L53 stuff, despite the fantastic dps. The raw data:

255 CHA: 0-1 minutes: 3, 1-2 minutes: 3, 2-3 minutes: 2, 3-4 minutes: 3, average: 1:58 (118 seconds)

199 CHA :0-1 minutes: 4, 1-2 minutes: 2, 2-3 minutes: 1, 3-4 minutes: 3
5+ minutes: 1, Average: 2:19 (139 seconds), Average w/out the outlier: 1:49 (109 seconds)

Now I have done experiments before (basically parsed my long huge log of charms). From what I can tell, the algorithm works something like this:

int split = magic(Level, MR, CHA)
if(rand() < ~0.9)
duration = rand(0, split)
else
duration = rand(split, 15)

So with the 199 cha I was lucky enough to get 1 super charm which I did not get with the 255 cha case.

I am going to go out on a limb and guess that charm durations are linearly proportional to charisma and that charisma is softcapped at 200 like the other stats and gives a 50% return, so 255 cha is equivalent to 227.5. That should give about a +10% duration which matches nicely with experiments. But overall I would say we need more data. I'd love to see a few more people post data.

Still, on the whole I'd rather have 10% longer charm durations than 10% more HP, so I guess I'm going to have to regear a little. Stupid int/gnome builds with 75 base CHA.
