Help me understand accuracy.
I'm running an ammochain build on Ao100 at the moment. I found a sniper weapon pack and thought it would solve all my accuracy problems, but I might be wrong. If I'm understanding this correctly, all it does is negate the accuracy penalty for range.
What this means is that an agility mod is actually superior to a sniper weapon pack at close range (+1 vs. +0), equal at medium range, and inferior at long range. Am I correct? What are good mods to put on a plasma rifle for my build (please, nothing higher than basic assemblies; haven't found them yet). I have a sniper weapon pack; maybe an agi to round things out? How much accuracy is enough?
Accuracy is a 3d6 roll. The plus bonuses are increases to the maximum roll needed to hit (rolling lower is better) and 10 is the base line (50% chance) Without counting any penalties, including from range, anything more than +6 won't do any good, since rolls of 17 and 18 always miss.
At line of sight range, anything more than +8 doesn't help you, and line of sight and running means anything more than +10 won't do much good unless you are firing at something outside your line of sight, which has a separate 50% failure chance if the shot would otherwise hit.
The first sniper pack removes the distance penalty, so anything more than +6 (+8 if running) wouldn't do any good. The plasma rifle has +2 Accuracy, so at close range, it's 74% chance (12 or lower on 3d6), medium range 62% (11), and 50% at line of sight (10). Adding an agility mod makes these 84%/74%/62%. Adding the sniper pack will make it 74% across the board, and 37% for anything outside of your line of sight (which without it would eventually bottom out at 1%)
The only basic assembly you can make on the plasma rifle is high power weapon, which is damage bonus / reduced weapon clip size, and thus you wouldn't be able to add the A or S mod to it.
