To Hit vs Proc.
 

Does anyone know how stats factor into To Hit and Proc Rate?

Is ATK what determines your hit rate, and STR the only stat which affects ATK?

And likewise for proc rate, DEX is the only stat which affects it? Does DEX affect hit rate? Thanks for info friends-

STR affects how hard you hit and your ATK which affects how often you hit. Dex affects your proc rate and only your proc rate.

Str = Damage (theres a formula somewhere that determines your max hit dmg based on weapon damage, str & offense skill).
Atk = Chance to hit and how close to your max damage you hit. Atk is modified by your Str.
Dex = Proc rate, thats it.

High dex does tend to increase chances of hitting and hitting for max for archery, as well.

Dunno if this is true or not. Probably is though.

Dex also affects crit rate on a warrior (crits are essentially a proc). Or crits for bow/thrown daggers for rangers/rogues.

My bad. I should have clarified that I was speaking in just the context of melee attacks.

absolutely nothing affects your chances to hit with melee weapons.
ATK (which is derived from STR and skill) increase the chance of penetrating enemy armor and dealing damage.
The confusing part here is that when you hit for 0 dmg, you see "missed" message, which doesn't reflect what has actualy happened properly. So its not possible to know for sure if you miss the target or you hit for 0 damage

So when people say you hit more often with higher ATK, in fact seeing more non-zero hits, but actual hit chance never increases

Weapon skill doesn't affect your chance to hit? I am enjoying missing with my 0 2HB skill on my bard. Allows me to keep things mezzed while I port, cuz I sure as hell can't tank em.

you not missing - you hitting for 0 damage ;)

Nah, I'd see those numbers. They'd average out to about what I'm hitting now with weapons I have skill for. MMMM, bard DPS. Tastes good, but always leaves you hungry for more.

It's been over a year since I've looked and it may have been changed in the p99 branch of the eqemu source...

but IIRC the only thing that your 'hit or miss check' is based on is level difference and the agility of the target.

This is exactly right. Nothing on the attacker's end affects hit chance, except of course for weapon skill. The defender's agility is likewise irrelevant except for the miniscule amount of AC it provides. Agility doesn't increase your dodge chance, and its only defensive purpose is the 1AC/3AGI or however much it is.
