Focus Accuracy from Mace Mastery Epic

I am looking to free up some slots and was wondering about Focus Accuracy from the Mace Mastery Epic Pool.


Looking at some of the accuracy scores with Focus Accuracy active in mids. For example Fulcrum Shift - 2 Accuracy, 1 Range and 1 Recharge all level 50 IO's. Total accuracy 293 percent.
With only 1 accuracy it drops down to 245.7 Percent.
With NO accuracy and just Focused Accuracy it drops down to 196.7 Percent.
These scores of course include set bonuses also, and not just plain FA and FS slotted.

I know that mobs, Bosses, Elite Villains and AVs can hit you with hit debuffs.

My simple question is what hit accuracy score is a safe range to be at without failing to hit ? If there is such.

Maximum ToHit

All players and critters have a maximum ToHit that varies from +95% at level 1 to +200.35% at level 50 (and, for critters, up to +211.10% at level 55). Counting against these maximums, however, is the innate +75% that all players get and the +50% that all critters get as part of the game's internal basic attack mechanics.

_________________________________________________

Am I understanding that anything above the 200.35% is over kill ? So in my explanation above Mids is showing 293 but the game is just seeing 200.35% ?

Or do I have a 293% and once the game calculates the debuffs from the mobs the most I can have is 200.35%? So if a boss drops a 25% debuff ( Darkest Night 6 slotted with Hit Debuff ) on me making my total hit { Pause while I pulled out the calcuator } 293% - 25% = 268% . Does the game now just automatically drop my hit total down to 200.35% because I am beyond the game limit ?

I know the explanation above me somewhat does not make sense, because what would be the point of having a " LIMIT" if your getting calculated on scores beyond that limit. I am seeing it in Mids Hero builder so I am thinking they might know more then me on these matters.

IF I have a 293 before debuffs are calculated, then my question is what is a safe Hit total to have ?

Is there a standard hit debuff value each mob puts out or is assigned, if they have a debuff attack ? EG do LT drop a 20% debuff, Bosses 40% debuff, Elite 60%, and then finally AVs dropping a 80% debuff ? This of course would make it easier as I would just adjust for the greatest debuff I would encounter. I didn't see anything in the Wiki as to the max hit debuff a mob can put out, this is why I am asking this over complicated question.

FA is a complete and utter waste of a power for PvE. High base endurance cost for little benefit except tohit debuff resistance.

If I'm reading you right, your question is: "I'm running FA, can I skip Accuracy IOs in my other powers?"

The complicated to-hit equation:

NetToHit = (InherentAttackAccuracy) * (1 + AccuracyEnhancement) * [ BaseToHit (75%) + ToHitBuffs - ToHitDebuffs - (Defense - DefenseDebuffs) ]

FA raises your InherentAttackAccuracy by a unenhanceable 20%. IO set global attack bonuses affect this same part of the equation.

FA also raises your base (75%) To-Hit by an enhanceable 4.25% (up to ~7%). It also has a 55.36% Resistance to To-Hit Debuffs.

Accuracy IOs slotted in powers affect the AccuracyEnhancement score.

So, as you can see, they're affecting different things.

Personally, I've never been a big fan of leaving FA up all the time, esp. for Corrs who can easily run into Endurance issues. Unless you're a rad with perma-AM, I'd usually save it for AVs and Arachnos only.

If you want more detail (and a more precise answer to your question), I'd suggest you post this over in the Scrapper forum. They've had FA for longer, and have several secondaries that make Endurance so plentiful that FA can be a constant. Also most of the hardcore number crunchers pay the most attention to that forum.

I think your problem is that the final accuracy number you see on Mids is rather simplified. It combines your +tohit bonuses and +accuracy bonuses and pits them against an unmodified, even-con enemy. As such, it will show the unmodified accuracy of most attacks as 75%, and if you're running Tactics, Mind Link, Follow Up, Aim, and Vengeance on top of heavy accuracy slotting in a power and +accuracy set bonuses, it very well may display as over 400%.

The ~200% cap you mentioned earlier is specifically the +tohit cap, not the +accuracy cap, and as Harkness' equation showed, those are treated separately. Without getting too mathy, +tohit is added to your base tohit chance, and then multiplied by +accuracy. Ideally, you will want a balance of each for maximum effect. +Accuracy works better against higher level enemies' level mods, while +tohit is more valuable to counteract an enemy's +defense or -tohit debuffs; if you're trying to hit a Nemesis boss that just got 5-stacked Leadership from his lieutenants' demise, all the +accuracy in the world won't make much difference, but a lot of +tohit could let you slice right through them.

As to your initial question, don't just look at what the simple box on Mids' says if you're trying to see if you are "accurate enough" - look at what you are trying to plan for. "Accurate enough" to not whiff when running +2 radio missions against generic baddies, or "accurate enough" to keep hitting against +2 Nemesis with X levels of Vengeance up, or "accurate enough" to hit +4 Captain Mako through his Elude on the STF without needing to pop yellows/Geas?

Generally speaking, I don't find Focused Accuracy that useful, at least for the cost. It doesn't do much +tohit anymore, so for situations where you want +tohit, you're better off with Tactics for more oomph and much less endurance. It does a decent bit of +accuracy, but only the equivalent of a shiny +3 DO, or a standard Insight, or ~3 medium set bonuses' worth. If you genuinely have bottomless endurance (you're a kin after all) then you might as well grab it if you have nothing else that interests you, but it's not all that wonderful.

Thanks for the responses, I need to re-read it a few times to sink in but I got the gist of it. It did help me move over to Maneuvers and Tactics, which seemed tons more group friendly.

More group friendly, less expensive and better at delivering stuff you really need. Accuracy is super-easy to get from set bonuses and regular IO content. You'll get tons of it without really trying.

Since you mentioned tohit debuffs above, one thing about FA that often gets overlooked or discounted is that it also provides something like 60% tohit debuff protection.

Yeah, I know, a lvl 41 power to fix something that's mostly an issue in the 15-25 range.

you should spec into BOTH leadership tactics and focused accuracy, YOU'LL HAVE SO MUCH ACCURACY!!

In pve I always have trouble hitting things but not after I got aim tactics and focus accuracy, no missing lol!

resting after every mob is kind of a drag though, pve can be so hard sometimes :\
