Got a little work done tonight, nothing I wrote about above, was more looking at the endurance implementation. Some things:

The calc max endurance formula used is wrong, while trying to simplify it certainly makes it easier to read it also leads it to some pretty bad rounding errors. My warrior lost a good 800 endurance with your simplified version.
This is the new version I wrote that didn't use non standard min/max() and added in commenting so the logic is understandable
Code:
//Info taken from magelo, it's a *little* off but accurate enough.
void Client::CalcMaxEndurance()
{
	//"Stats" the total of (Str + Dex + Sta + Agi)
	int Stats = GetSTR()+GetSTA()+GetDEX()+GetAGI();

	//"Levelbonus" your Level * .075
	//Endurance = level * 15 plus

	//Levelbonus times the sum of the next 4 lines (this is calculated on each line, not at the end because of rounding errors otherwise)
	max_end = GetLevel() * 15;
	//plus lesser of Stats and 800, divide that by 4.
	max_end += int((Stats>800?800:Stats)/4)*0.075*GetLevel();
	//plus bigger of (lesser of Stats and 800)-400, and 0. all of that /4
	max_end += int((((Stats>800?800:Stats)-400)>0?((Stats>800?800:Stats)-400):0)/4)*(0.075*GetLevel());
	//plus bigger of (lesser of Stats and 800)-400, and 0. all of that /8
	max_end += int((((Stats>800?800:Stats)-400)>0?((Stats>800?800:Stats)-400):0)/8)*(0.075*GetLevel());
	//plus bigger of (Stats - 800 and zero) / 8
	max_end += int((Stats>800?Stats:0)/8)*(0.075*GetLevel())*2;
	//plus bigger of (Stats - 800 and zero) / 16 
	max_end += int((Stats>800?Stats:0)/16)*(0.075*GetLevel());
	//plus our endurance from items and spells.
	max_end += spellbonuses.Endurance + itembonuses.Endurance;
	//Maurice of Magelo fame explained that we can't simplify the statements 
	//because we have to round every step of the way.
}
Also something appears up with how stats are calculated for clients, I'm not sure exactly where there's a problem but well let me show you:

Sarrie 65 War naked
http://i8.photobucket.com/albums/a2/...rite/naked.jpg

Sarrie 65 War with her full gear on
http://i8.photobucket.com/albums/a2/...e/notnaked.jpg

It appears almost like itembonuses are being counted twice serverside. Ex. Sarrie had +86 wisdom fully geared and had a base of 70 shoulda been 156 serverside like clientside but was 242. 70 + (86*2) = 242. And obviously stats aren't capped correctly which is gonna mess with hp/mana/endurance calculations, among other things.

Not exactly sure what causes it though.
Also though I haven't gotten around to testing it I'm pretty sure this is the case:

In the itemfield encoding for titanium I believe
Code:
/* 083 */	I(AugSlotType[0])
/* 084 */	I(AugSlotUnk[0])
/* 085 */	I(AugSlotType[1])
/* 086 */	I(AugSlotUnk[1])
/* 087 */	I(AugSlotType[2])
/* 088 */	I(AugSlotUnk[2])
/* 089 */	I(AugSlotType[3])
/* 090 */	I(AugSlotUnk[3])
/* 091 */	I(AugSlotType[4])
/* 092 */	I(AugSlotUnk[4])
is actually backwards with the unknown spot coming before the slot, I believe that's why aug slots don't appear on items for titanium.

I'll try to look into all this a little bit more and get some more info.

void Client::CalcMaxEndurance()
{
	//"Stats" the total of (Str + Dex + Sta + Agi)
	int Stats = GetSTR()+GetSTA()+GetDEX()+GetAGI();

	//plus bigger of (lesser of Stats and 800)-400, and 0. all of that /4
	max_end += int((((Stats>800?800:Stats)-400)>0?((Stats>800?800:Stats)-400):0)/4)*(0.075*GetLevel());

	max_end += int(((Stats-800)?(Stats-800):0)/16)*(0.075*GetLevel());
	//plus our endurance from items and spells.
	max_end += spellbonuses.Endurance + itembonuses.Endurance;
	//Maurice of Magelo fame explained that we can't simplify the statements 
	//because we have to round every step of the way.
}
Was two typos in the calcmaxend I made, what I get for working while tired.

The double stats comes from functions that use the Mob::Get<somestat>() that instead of return <somestat>; return <somestat> + itembonuses.<somestat> + spellbonuses.<somestat>. Not what solution there would be other than making sure code that involves clients uses client::getstat instead of mob::getstat in the code, which will probably be a little tedious given the amount of times they're referenced.

The aug thing, I'm not sure how they're serialized in the code yet so take that with a grain of salt but I confirmed when I set in the database:

augslottype1 = 0;
augslot1unk = 7;
That I created an item with an aug slot of 7 clientside, trying to apply it to an item was a little troublesome. I successfully inserted the augment into the item, however after you finish the insert the items in the pool are not deleted immediatly and attempting to remove them causes the client to crash, so obviously some work to be done there.

The glow message thing appears to work, and tested recourse; took out old recourse code and replaced it with this in spellontarget rightbelow where resists are calculated.

Code:
	if(spell_effectiveness == 100)
	{
			// Recourse means there is a spell linked to that spell in that the recourse spell will
		// be automatically casted on the casters group or the caster only depending on Targettype
		// solar: this is for things like dark empathy, shadow vortex
		int recourse_spell=0;
		recourse_spell = spells[spell_id].RecourseLink;
		if(recourse_spell)
		{
			if(spells[recourse_spell].targettype == ST_Group || spells[recourse_spell].targettype == ST_GroupTeleport)
			{
				if(IsGrouped())
				{
					Group *g = entity_list.GetGroupByMob(this);
					g->CastGroupSpell(this, recourse_spell);
				}
				else if(HasOwner())
				{
					if(GetOwner()->IsGrouped())
					{
						Group *g = entity_list.GetGroupByMob(GetOwner());
						g->CastGroupSpell(this, recourse_spell);
					}

				}
				else
				{
					SpellOnTarget(recourse_spell, this);
#ifdef GROUP_BUFF_PETS
					if (HasPet())
						SpellOnTarget(recourse_spell, GetPet());
#endif
				}	

			}
			else
			{
				SpellOnTarget(recourse_spell, this);
			}
		}
	}

Now some actual changes:

-Fixed the atk mlog bug, again.
-Changed how recourse works
-Made glow messages only go off for instant spells
-Changed how haste is calculated to account for caps and stacking correctly and to make sure we account for overhaste spells(ex warsong of the vahshir). Should fix one of the current dev issues with wonderous rapidity and nature's melody etc etc.
-The way hundredhands is calculated isn't correct, but I wasn't sure how to address it so I kept it the way it was implemented for now but replacing the true/false with actual effect values.
-Changed the end calculations slightly (but in a big way) GetLevel()*0.075 is added in every line to address some pretty massive rounding errors if you try to simplify it, we're talking a loss of 8-900 endurance when you get up in pop gear kinda rounding errors.
-Special Messages should be able to show a type other than 0x0A.

And svn created me a nifty little patch file

Another quick change. Did this pretty quickly so tell me if I messed any part of it up.

Dunno if it bothers anyone else as much as it bothers me but the small quickly used timers for the hard coded client skills keep bugging out on me, my sneak is down for the next 11 days according to my database for instance =(

Not sure at all what causes these short timers to bug out so I added a rule here on whether or not to enforce them, I mean do we really need to enforce them? They're hard coded into the client and it's going to be pretty rare that someone hacks into the client to change the timers, most are only a few seconds anyway.

Also threw in another rule that helps server admins modify the endurance regen since there really isn't any way to raise your regen outside of +endurance regen items, and def seems like something admins might want to change, just like an exp modifier.

new rules:

RULE_BOOL( Character, EnforceSkillTimers, false )
RULE_REAL( Character, EnduranceRegenBonus, 1.0 )

http://hmproject.org/files/timers.patch


Also would like to add that I love this rule system, it's a brilliant concept.

People will hack the client for the timers, trust me. Instant Back Stab for instance.

This was added in because of the amount of people that were hacking the client.

I love you man!

These are some seriously bad-ass fixes. I'm gonna patch up the server and see the changes. Will report back if I see something out of the ordinary.

Keep up the awesome work!

I'll look for what's happening to the shorter timers, I don't notice it happening with any of the longer ones, my disc timers for instance but it's certainly happening with some of the shorter ones kick sneak hide Feign. That's just there till I figure it out.

Edit: Alright, here's something I found with persistant timers, first I misread the timer in my database last time that led me to the rule conclusion it was really set to 0, 0. If a timer is set to duration 0, enable 0 in the database it wont count as expired, and apparently sometimes when removing timers instead of them being removed from the DB they get set to 0, 0 thus that skill is now bugged for that character(gg). Not sure of a fix yet but yeah thanks for not letting me take the lazy way out with my rule I guess.

overall the changes look good.

make sure you default any new rules to how they were before you added the rule... aka EnforceSkillTimers to true.

interesting about the item bonuses being counted twice... have you checked #showbuffs to see how it compares?

also in the endurance calculation, what I put in should have matched your original version here:
http://www.eqemulator.net/forums/showthread.php?t=21661
I am assuming that the int() operators in your original code were being used in place of floor()... but in any light, the 0.075 * GetLevel() in your oringinal code was outside the int(), so it should have had the same rounding effects as my code. If you are really not intending to floor() those numbers, than instead of multiplying out each time like you did, just change the variables in that function to be floats and then use max_end += bonus_sum * GetLevel()*0.075; at the end. (converting an int to a float or vise versa is generally a rather computationally expensive operation, and should be minimized)
