Skill Mod Details

The camouflage modifier works similar in the way mask scent modifier works with the exception that camouflage has a slightly higher success rate and that it also works vs NPCS.


What does the camouflage skill modifier do?

The camouflage skill determines the rate of success for the /conceal effect.
It has no impact on /maskscent, which maxes out at Master Scout
The success rate for /conceal is capped at 98%
So what does increased camouflage skill actually do then?
Let’s try a couple of examples then (these are fictitious values, simply to prove the effect):

Scenario A:
A Ranger with +100 Camouflage skill
A creature of CL 25
Result:
Success Rate of 98%
Scenario B:
A Ranger with +125 Camouflage skill
A creature of CL 25
Result:
Success Rate of 98%
Even though the Camouflage skill is +125, the success rate caps out at 98%
Scenario C:
A Ranger with +100 Camouflage skill
A creature of CL 35
Result:
Success Rate of 90%
The higher creature level has reduced the success rate compared to the CL 25 scenario
Scenario D:
A Ranger with +125 Camouflage skill
A creature of CL 35
Result:
Success Rate of 98%
The higher Maskscent has increased the Success rate back up to 98% for the tougher creature

Again, note these are fictitious values, I don’t know what the baseline Creature Level actually is. 

Formulas

1. Needs formula for how detection range affects it

2. Needs formula for how skill modifier works with it and vs CL of mob.
