-to hit = how much defense?

Just wondering if anyone had a handy formula for converting -to hit to +defense and vice versa, thanks!

They work exactly the same.*

The only difference is how -tohit can be resisted by higher level mobs.

Here, look at the formula for final chance to hit:

HitChance = Clamp( AccMods × Clamp( BaseHitChance + ToHitModsDefMods ) )

Tohit is in the same place as defense, so every % of -tohit acts exactly like a % of defense.

More information here.

i think its approximatly 1:1 conversion, but you have to take into account the fact that the enemy most likely can resist the -tohit and the -tohit is only applying to the baddies hit chance not all the baddies targeting you

Good point, but there is an often overlooked benefit to this. Tohit debuffs will benefit your allies as well.

I'm thinking about a power like smoke. Does smoke even have a hit check, seems auto hit.

Smoke is autohit, but that's a property of the power. Many -tohit debuffs are attached to powers that must hit their target before the debuff is applied. Even if a power is autohit, the effect can be reduced by the target's resistance to that kind of debuff.

One other thing to note about -tohit debuff is that it affects all forms of attack coming from the affected target, so long as they require a tohit check at all. There is no such thing as a "-tohit with lethal attacks" debuff, whereas you can have a defense buff that only applies to a subset of attack and/or damage types.

Just a note, smoke's -perception is auto hit, but it's -tohit component requires a check. So no matter what, the enemies will have a harder time seeing you, but their tohit may not get debuffed. But something else that I *think* is unique to smoke, is that its tohit debuff is non resisted if it hits.

1 point of -ToHit is equal to 1 point of +Def (all vectors, all types) for +0 and lower minions and underlings.

Lieutenants resist -ToHit by 10%.

Bosses resist -ToHit by 20%.

+1 critters of all ranks resist -ToHit by 10%.

+2 critters of all ranks resist -ToHit by 20%.

+3 critters of all ranks resist -ToHit by 35%.

+4 critters of all ranks resist -ToHit by 52%.

+5 critters of all ranks resist -ToHit by 70%.

This resistance increases with level difference, up to 99% at +12 and above.

<edit>
Additionally, I should note that the rank-based resistance is discrete from the level-differential resistance. I forget whether they're factored independently (one resistance calculated before the other is applied) or added together and factored as a single total. I did have that information somewhere, but I've forgotten where... if I find it later, or decide to spend the time testing it again, I'll put it up here.
</edit>

AVs with the Resistance power resist -ToHit by a scaling amount, dependent on their level. A level 50 AV resists -ToHit by 85%, for example.

-ToHit powers flagged as "unresistible" ignore AV Resistance, but not level-differential or rank resistance.

So the answer is, there is no specific answer. How closely -ToHit will equate to +Def (All) will be different for every fight, due to different levels of critters, different mixes of minions, lieutenants and bosses in spawns, etc.

No. Smoke Grenade requires a hit check for the -ToHit property. Smoke, from the controller Fire Control primary, is autohit across the board (in PvE).

This property of -ToHit make DM/?? or ??/DM pretty fine for melees of all sorts. See DM/SR anything for examples.

i'm pretty sure the Night Widow Smoke Grenade is autohit for both aspects of the power, as well as having an unresistable tohit debuff. It can't be slotted for accuracy and also appears to work the same in both PvE and PvP.

Stalker's -tohit "demoralize" effect from Assassin's Strike isn't resisted, either. Other than that, nothing really to add: everything else has already been said.

Well, yes. Still, i had to double check since i was pretty sure that the Smoke Grenade i usually use was autohit with an unresistable tohit debuff and i'd missed the part where you mentioned which smoke grenade you were talking about.

What everyone else said, plus one addition.

-ToHit is type unspecific. It not only helps you cap off whatever your highest defenses are, it supports your weakest ones too.

The only thing I'm unsure of whether it also helps against attacks that are truly of type Untyped that no defense exists for.

Well, there is a specific answer. Tohit debuff and Defense have a 1:1 ratio, exactly. There's just a caveat: The debuff you use is rarely the value applied.

It should. It's modifying the attacker's tohit value. If the attack requires a tohit roll then using a tohit debuff will lower the attack's chance to hit by the final debuff value that is applied. So if the enemy's tohit is normally 50% and the final (after rank, con, and all other modifiers are applied) debuffed value is 45% then they have a lower chance to hit regardless of whether or not you have defense.

That reminds me: the next Hami raid i go to i'm going to tag Hami and his Mitos with my Widow's Smoke Grenade and use a power analyzer on them.

There's no such thing. There's untyped damage, but there isn't an untyped attack vector. You can omit attack vectors entirely (in which case defense doesn't apply), but by nature, every existing attack vector has a corresponding defense type.

i took it to mean attacks that require a tohit roll but have no defense tags associated with them. Hamidon and his Mitos are the most common example that comes to mind.
Which is where tohit debuffs are always stronger than defense. (Except possibly PFF IIRC since it buffs Base Defense.)

I believe Hami and the Mitos are autohit though... at least I don't remember ever seeing one of them miss.

Yellow Mitos at least can miss with their blasts. However, they have 300% +toHit and the blast has 150% accuracy, meaning that they basically only miss because they are forced to miss on any attack roll of 5% of less.

I've had the blast from a yellow chase me out into the hills and not actually strike me on several occasions.

Hami's own attack is, indeed, auto-hit.

Fulcrum Shift has no attack vectors, either.
