Difference between ToHitDebuf and Acc. ToHitDebuf?

What is the difference between a To-Hit-Debuff and an Accurate To-Hit-Debuff?

For example Gloom of the Soul Mastery patron set has both of these.

Thanks

Accurate To-Hit-Debuff is used on powers that De-buff To-hit and require a hit check (they take accuracy enhancements).
An example is the toggle power Darkest Night, which is applied to a target and affects all those around him, but doesn't need to check if it hits the target. It takes To-Hit-Debuffs but not Accurate To-Hit-Debuffs because there is no check to see if it hits the target, and therefore the power takes no accuracy enhancements.

Edit to clarify and add: Accurate To-Hit Debuff sets will have some enhancements that increase the power's accuracy, whereas To-Hit Debuff sets have no enhancements that increase accuracy.

thanks for the reply, but the top part is clear as mud.

Okay, I think I made it less muddy.

<goes and starts another pot of coffee>

To put it another way: Accurate ToHit Debuff sets increase the powers' accuracy. Normal ToHit Debuff sets do not include any Accuracy enhancers.

We've been saving Paragon City for eight and a half years. It's time to do it one more time.

greatly appreciated Katze and KitzuneKnight. thanks a lot.

Accuracy of the To-Hit Debuff i think is refering to how accurate your power is to hitting something and appliying the To-Hit Debuff aspect to the target. If you're boosting the accuracy of a To-Hit Debuff, your increasing the chance of the To-Hit Debuff to actually hit its intended target.

Some powers always hit, so they don't need accuracy boosts. Most powers have a 'hit-check' which the chances of that power hitting are increased by the accuracy enhancements.

If I'm wrong, someone just tell me and I'll leave it be. I think thats what he wants from the sounds of his question.

EDIT: OH...we're talking about the IO Sets. Gotcha. Yeah, what they said. They added the Accurate To-Hit Debuff (among others like Accurate Healing, Accurate Defense Debuff, etc) because at first the To-Hit Debuff IO Sets rarely (if at all) had any accuracy enhancement in them.

OK, let's take Shadow Maul as an example of an "Accurate To-Hit Debuff" power.

It requires a to-hit check. If you slot it with six of a "to-hit debuff" set it will be nearly useless, because it will miss all the time. Therefore, you would want to 6-slot it with an "Accurate to-hit debuff" set for, well, accuracy.

(Of course, that would STILL be a bad idea because of the lack of damage enhancement, but work with me here. )

Darkest Night does not have a to-hit roll. It's automatic. Accuracy in that power would be wasted. It works just fine 6-slotted with a "To Hit Debuff" set.

Accurate Heals and regular heals are a similar thing; consider Dark Regeneration. You can't 6-slot with Heal sets for a juicy final bonus without risking misses at crucial times. Therefore, Accurate Heals (and Accurate To Hit Debuffs, and Accurate Defense Debuffs) were created.

If you're just looking at the power description on your enhancement management screen, then the section of that description that you're looking at tells what IO set types the power will accept.

The difference between "To-hit Debuff" and "Accurate To-hit Debuff" is that sets of the latter type will include IO's that buff the accuracy of the power they're slotted into, and can, IIRC, only be slotted into powers with that type of effect that require a to-hit roll to affect the target.

So, for example, Gloom is an attack that has a secondary effect that debuffs the target's to-hit value (makes them less accurate), but it requires a to-hit roll to see if the attack hits the target. If it misses, the debuff doesn't get applied. Because the power requies a to-hit check, it can accept IO's from "accurate to-hit debuff" sets, and can also accept regular to-hit-debuff IO's.

On the other hand, a power like Radiation Infection, a power with a to-hit debuff effect from the Radiation Emission powerset, is auto-hit, so it doesn't (again IIRC) allow accurate to-hit debuff enhancements (at least the in-game documentation says it doesn't), because it doesn't require a to-hit roll to effect the target.

Part of the reason I wanted to talk about "accurate heals" is that it's a more obvious separation between "whether it hits "(the accurate part) and "What it does when it hits" (debuffs THEIR accuracy.)

If he's slotting for To-Hit Debuff, chances are he's looking to debuff the targets to-hit cause he gets enough damage from other places. I do this with eye-lasers from the body mastery epic pool on my scrapper...plenty of damage from other powers in my set, but 6 slotting with the Lady Grey set made a big difference in an AV fight a couple times. Before using it, we weren't making a dent (me, a bubbler, and another defender who couldn't debuff the AV). Once I started using it as soon as it popped and debuffing the AVs defense (or maybe resistance, can't remember which right now), the group of us actually started making a dent in the AV.

excellent stuff Fulmens and sigma1932

I meant "in Shadow Maul", one of your big hitting powers. I may not have been clear.

There are a number of attacks that can take buff/debuff sets of one kind or another. Whether you want to use those sets in an attack is another question entirely, since they often don't provide the kind of enhancement most people would want in an attack; Accuracy and Damage in particular. (Which is not so much of an issue in powers whose primary purpose is buffing/debuffing.)

So in most cases it's not worthwhile to use more than a slot or two of a buff/debuff set in an attack that you want to use as an attack. You can do it, of course, but it's generally considered a bad idea if you want to defeat foes at something other than a glacial pace.

oh, i wasn't even entertaining the notion really. i am going to throw Apocalypses in it.

just wanted to know the difference. thanks everyone.
