Chance to hit calculations from Mids

Hi All,

I am just making a spreadsheet for chance to hit and am not 100% sure which number I should be taking from Mids.

For those who don't know, the formula is:

HitChance = Clamp( AccMods × Clamp( BaseHitChance + ToHitMods – DefMods ) )

The number I am querying is the AccMods number, in Mids I can look at a power and see it say Accuracy = 179.2% (Which would be 1.792 in the equation) but when I hover the mouse over it says Realnumber = 2.04 and I am not sure which I should be using - can anyone help?

Note: If it is the first number then purple sets don't give enough accuracy to help hit +3's 95% of the time, which i find surprising.

is that including global acc bonuses you have from set bonuses? theres a good bit of sets out there which include +acc to all powers (for purples its like +9% acc to all powers, some other sets are like 6-7% acc to all powers)

maybe thats where your missing amount is

Actually Paragon Wiki has come the the rescue!

AccMods = the power's inherent Accuracy × (1.0 + the power's Accuracy Enhancements + all global Set Accuracy bonuses)

So 75 x (1 + 0.55 + 0.6625) = 165.9.

I am still confused what the realnumbers bit means though, but at least I think I can safely ignore it.

Edit: It still leaves purple sets woefully lacking in accuracy imho Something they seem to have noticed if the numbers on Superior Scrappers Strike are anything to go by.

What Mids displays as "accuracy" is your final chance to hit with that power. I'm not sure what the "Real Numbers style" accuracy it displays on mouseover is; I think it's supposed to be the power's accuracy stat, as displayed by Real Numbers in game, but that doesn't quite mesh with the numbers it's showing.

The good news is, you can easily make Mids do this for you without a spreadsheet at all. In the example you gave, you've got a final hit chance of 179.2%. Of course, that's capped in-game at 95%. But if you're using the default settings, it's telling you your chance to hit a +0 enemy, which is usually trivial. You're probably interested in hit chance against high-level enemies; I usually try to build for capped accuracy against +3s, since you basically never face worse than that once you have an alpha shift. According to paragonwiki, the base hit chance against a +3 is 48% instead of 75%, so you can go to Options - Configuration - Exemping and Base Values and change the 75 to a 48. That will make Mids display your actual final hit chance against a +3 enemy as the "Accuracy:" number. You can plug in any other number you like for base tohit, to account for enemies of different levels, or for defense buffs/tohit debuffs.

The power's inherent accuracy here is not 75 (at least, not for any attack that I can think of). That's your own base tohit stat. The power's inherent accuracy is 1.00 for most powers, but some have higher or lower. I'm also a little puzzled how you obtained 66.25% accuracy from set bonuses, since AFAIK they only come in whole numbers... Double Super Edit: Unless those numbers switched order and the 55% is your set bonuses.

You are correct that a purple set in most attack powers will not, by itself, cap your hit chance against +3s. However, when combined with the rest of your build, any power slotted with a purple set should quite easily reach 95% hit chance.

Sussed it now lol

Thank you ever so much Hopeling
