I think there are a series of tables and offsets. Finding every table will be hard :(

Characters
 

Only Defense, and AGI are active skills/stats for these characters if no other skills are listed. To gain more data, I took screenshots of my character stats and skills at times when he was so injured that his AGI (and thus his AC) went down.

The Gnome Rogue and the Troll Warrior are on the same AC/defense schedule. The Mage skips ahead some on its schedule.

Screenshots exist for this data.

Was incorrect in my Dodge skill... it is at 230, not 225.

Grummet

So, is it your desire to get a bottom and top and then make a reasonable approximation formula with offsets for class/race, rather than a 100% compatible with live?

Just checking.

I'm saying that we may have to break the AC into chunks based on levels, and approximate. I really doubt a duplicate of AC can be made without seeing the source.

Using only 2 variables, with one constant (AGI) and the second incrementing by small values, I really don't see how rate of change can move from 1 to 3 to 2. It almost makes me wonder if EQ uses an approximation of a formula :P

The way I see it is that 99% of eqemu'rs won't be able to tell the difference anyway. Let's get this close by getting a lot of data, and forcing a series of best-fit lines based on the variables we can approximate. We can first approximate one variable's effect, then approximate the next, then build up from there.

killspree is working a dark elf rogue up the ranks with dodge and parry, and I'm doing a gnome rogue without dodge or parry. If we could get data of a third class rogue with dodge but not parry, then we could probably BS an equation for those skills for rogues. If we test it on another parrying class, and we get something close, we keep those skill approximates. We lock them in, incorrect as they are, and keep approximating data effects until we have wrong, albeit close, data produced.

works for me, just making sure.

btw, I do agree that it seems VI fudged a lot of this, or there are some pretty whacked equations with bizarre modifiers. :shock:

Work/school/girlfriend are eating away at my free time. Progress is moving very slowly right now. If anyone would like to attempt to process the information posted or would like emailed raw information that I have, just ask here or in PM.

Bump, posted more data in an above post.

Also, this is my 500th post!! Yaaaaay!

Looking at the data between the 2 similar classes at those levels, you see that level really isn't a factor, and that dodge isn't a factor as well. I hear that level 7 creates a new table. I will investigate that claim and post when I level them up.
