Focus Accuracy Power question

I posted up on the Corruptors forums, but it seems someone felt I might get a better answer here in the Scrapper Forum, since Scrappers have been playing with this power much longer then Corruptors.

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.

I am having issues understanding the max listed in the wiki and the scores listed in the Mids builder.

Am I to understand 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.

Okay. If you are taking Focused Accuracy to slot the to-hit buff... don't.

Focussed Accuracy gives a flat 20% accuracy buff, a buffable 5% to-hit buff, a non buffable perception boost, and a non buffable perception debuff resistance.

Even if you slam the To-Hit buff into ED, you'll only have a 7.71% (54% boost) to-hit bonus, and one of the highest end-consumption powers in the game. The base on tanks and scrappers is .78 end / sec, and even if you slam endurance reduction into ED with a 98.3% end reduction, you'll still be yanking down .39 end / sec.

So, if you are looking to shave off slots, just two or three slot Focussed Accuracy with Crafted level 50 Endurance Reduction IO's. Two such Crafted IO's will put you at .43 end / sec pull down, not much off the .39 end / sec that you could cap at.

It's also a good power to throw the Guassian Chance for Build up Proc on.

Now, as far as your accuracy boost goes... you never are going to be in a safe range without failing to hit.

Remember, NPC's always have a 5% chance to dodge... so your best to-hit rating is ONLY going to be 95%, no matter what else you do.

yeah, short story, its a crap power, mainly gotten by those who want to mule it.
Leadership: Tactics is better (as mentioned) and if you're spending on IOs anyway, go get the Kismet unique (its sad when a power can be beaten by almost that one single IO, FA is really overdue for some love)

FA also has res to to hit debuff. Kismet nor tactics or kismet + tactics will help you deal with the horrid amounts of to hit debuffs you run into in cov. As far as the math of your question, I'm not sure on but I don't think it would matter. Every alt I have that has foc acc laughs at all to hit de buffs and can hit everything with ease except triple stacked veng buffed nems, and a Lt+ cim in huge mob. So what if it cost a little more end. You are a /kin.

The only scrapper I took it on was my Claws/Regen....largely because he's the only one I have that can afford the ridiculous end cost. I'd prefer to take Tactics instead, but I wanted Physical Perfection, and I'm out of power pool choices anyway.

It helps in PvP against defense-based characters, and against Rikti Drones.....and, well, not much else.

It is harsh endurance-wise, but nice for more accuracy(even if the To hit buff is small, any is good), and +300 feet of perception. Very nice to have when fighting Night Widows. If you must slot it, focus on Endurance Reduction first. I usually 3-slot with Guassian's or 2-3 End/Buff HO's.
