CtH and armor

While sitting bored, I just made an analysis of chance to hit for various monsters vs my lvl 89 merc. I was wondering how far I should push his defence to make him a bit safer in the WSK. A graphical representation of the result is in the following linkl

As I interpret the graph, the first 5K is pretty much essential if defence should have any meaning at all, and 10K must be around the least acceptable amount unless you have high leech and/or blocking. Around 15K seems to be the point where the returns are going low, unless you can get it easily.

This is pretty much in accord with common knowledge on the forum, but I like graphs to gut feelings.

A to me more surprising result was that while clvl plays a factor, it is not a bit as drastic. I chose clvl 60 for cut-off, as it is about the lowest I had heard of. The graph is pretty flat, so it must be assumed troubles in hell is more about hitting things than not getting hit by things. Also, while more is better, you get roughly the same percentage improvement per level, due to the range of mlvls.

Wow, Thanks for the info!

I always wondered how much def should I shoot for on my mercs...

A to me more surprising result was that while clvl plays a factor, it is not a bit as drastic.

When calculating a good AR level for my chars, I never take the level difference factor into account.

I split the CtH formula in two pieces:

CtH = AR/(AR+Def) * F_ldiff,
F_ldiff = 2 * alvl/(alvl+dlvl),​

where F_ldiff is the factor which takes the level difference between you and the monster (or vice-versa) into account (alvl = attacker's level, dlvl = defender's level).

Let's say delta_l = dlvl - alvl, then

F_ldiff = 1 / (1 + delta_l / (2*alvl)).​

Let's say you're a lvl 80 char in hell fighting lvl 75 monsters. In this case F_ldiff = 1/(1-10/160) = 1,032 --> a 3.2% improvement in CtH compared to the bare AR term. The most extreme case would be a lvl 80 fighting Baal: F_ldiff = 1/(1+19/160) = 0.894. This is the only case I can think of where the F_ldiff factor becomes somewhat significant, but only for 9% still.

Re: CtH and armor

This is absolutely true, but you often see statements to the effect that chars should level to gain improved chance to hit and getting hit less often.
