BTW, do we as players have any way of knowing what the monsters' base chance to miss is??
And does that Chance To Miss go down in successive levels, or is it fixed by something like, say, the Level of the individual Monster??
(I'd hate to think that somewhere, someday, down the road, your Armors and Weapons devolve into uselessness by default since they stay the same and the monsters get stronger and quicker.)
If I'm not mistaken, there's no exact way to know the exact miss chance. The following is my guess based on battle buddy stat tracking and my own research.
Monster base hit chance is 75% (Tenb told us this). Going from there, Monster stats increase as they level. So, monster will increase hit chance based on their dex as they level.
Think of a regular monster as you, without equipment, auras or ap, just straight stats, but probably beginning at a weaker starting point than you.
Charkan - you no longer have a character evade stat that interacts with accuracy. So if a critter has an 80% chance to not miss, that is its base chance to not miss entirely, it is no longer balanced with character evade. In this example, 20% of the time the enemy will just plain wiff its attack. The other 80% on the time, it has a chance to land a hit on you based on your evade/block/parry/resist. Lets assume, for the moment, that you have 25% evade and no anything else. Of that 80% of the time that the monster does not wiff (8 out of 10 attacks) 25% of those will be evaded (2 of the 8). Thats how evade works now. So in the end, with an 80% acc monster and 25% evade for yourself, it will land damage on you 60% of the time (6 out of 10 attacks).
Sorry if I'm a bit number intensive but I can't think of a better way to explain it.
