Game Mechanics: AC may not be working correctly

Great video. I felt smarter just listening to it.

As you can see between 600ac and 800ac there is a noticeable improvement in mitigation. However, after 800ac it's a marginal difference. When tanking raid targets, there is little to no difference between 800ac and 1,000ac. Also consider the random number generator factor. In my opinion on P99 currently - HP still reigns supreme especially when engaging raid targets. Use this data for whatever you'd like.

Your sample size is sufficient to establish a pretty strong confidence interval. AC clearly caps off at some point. From what I recall of dev postings, there was indeed a hardcap on worn AC, but I feel like it's much lower here than it was on live. In retrospect, I'm sure that's why the devs put 40-50+ ac on items in Velious, because it wouldn't make as big of a difference as players expected it would.

One thing that would be beneficial to establish is how the AC equation works. Is there a difference in ac from defense, buffs, or gear. Does certain AC cap at a point? Is there a class cap? Etc.

I'm sure this has already been linked, but this is good reading: http://www.project1999.com/forums/sh...ad.php?t=48312

with velious on the horizon, what's the chance we could get the code for AC posted?

On live there was a softcap to ac, i believe it was around 289 worn ac,after the softcap returns dimiahed but did not go away. The advantage to plate wearers was the 289ac from softcap yielded more ac return. There was also believed to be a hardcap around 1300ac calculated, and this is why monks were able to tank so well in velious, because they could hit the hardcap by wearing the high ac itemz even though they didnt get the ac return of plate.

Just started p1999 up again and in doing some research came across this thread. Was anything ever solved in terms of AC being changed / formula being posted?

Apologies for the necro if so. Otherwise, I would be curious to see where we are at with this.

[Scrubosaur]

From what I understand the issue doesn't lie solely with how AC works but also on the amount of ATK rating of individual mobs. Even if the AC math matched classic EQ you would still need to know the attack ratings of mobs and how that factored into AC on a per hit basis.
