What is the highest critical chance and critical damage that is possible through items alone?

Is it possible to get 100% critical chance through items and how high can my critical damage get?

Please explain the gear needed. i.e. Bow with 100% critical damage with socket 100% critical damage = 200% critical damage

Solution 1:

Here is a list with max values for each slot of Critical Hit Chance / Critical Hit Damage

• Max per gearset: 54% / 450%

• gear slots: 7 / 5

• Weapn: 0% / 100% + (100% gem)
• Offhnd: 10% / 0%
• Shield: 10% / 0%
• Amulet: 10% / 65%
• Ring: 6% / 35%
• Belt: 0% / 0%
• Boots: 0% / 0%
• Bracer: 6% / 0%
• Chest: 0% / 0%
• Gloves: 10% / 50%
• Helm: 6% / 0%
• Pants: 1% / 0%
• Shldr: 0% / 0%
• Cloak: 0% / 0%
• Mighty Belt: 0% / 0%
• Spirit Stone: 6% / 0%
• Voodoo Mask: 6% / 0%
• Wizard hat: 6% / 0%

As you can see the Max per gear set is: 55% for Critical Hit Chance and 450% for Critical Hit Damage, this does not include legendary or set items, that could increase these values even further.

Even with skills like + 10% from Archery and + 2*6% Demon Hunter Skill Bonus: Multishot (+Crit) you will only have 64%. It should not be possible to reach 100% Critical Hit Chance with any gear.

Edit: Actually you could go for 2 weapons instead of one and so you can get 650% (another 100% + 100% socket) Critical Hit Damage.

I made a rough estimate what your maximum DPS could be:

Assuming you have a 1500 DPS weapon with a socket, 3008 Main Attribute (DEX) and 1,9 APS (with best modification), 54% Critical Hit Chance and 450% Critical Hit Damage you will get about 380k DPS. Assuming you have even more damage modifications like +20% more damage from certain skills / passives will allow you to output about 460k+ DPS.

Demon Hunters can gain an extra 7% from the two item bonus of Natalya's Wrath. The only legendary that provides a crit bonus in a non-standard slot is Inna's Glory, providing 1% in the pants slot.

Wanderlust (ring) + spirit of adventure (amulet) gives set bonus: endless journey, which gives +50% critical hit damage?

Solution 2:

Crit Chance on Gear: 54% - 59.5%
Crit Damage on Gear: 385% - 604%

Crit chance and damage from gear depends on class due to class-specific legendary items, and the ability of some classes to dual-weild.

Also, note that you cannot achieve both maximum crit chance, AND crit damage at the same time, because max chance requires a shield, and max crit damage requires dual-weilding. Classes without dual-weilding can achieve their personal maximum in both.

Demon Hunters have the best all-around crit gear opportunities, with the highest crit-chance, and a tie for the 2nd best crit damage.

Barbarians have the best crit damage, and the 2nd best crit chance.

Monks tie for 2nd in crit damage opportunities, and tie for last in crit chance.

Witch Doctors and Wizards have the worst opportunities for crit gear.

Crit Chance above slot-max from Legendaries and Set Items:

  • Non DH only get 2.5 more by getting this set, since they lose a 4.5% ring.

Only Barbarians can use the Legendary Mighty Belts, and Witch Doctors and Wizard's can't Dual-Weild, preventing them from getting a 2nd weapon and weapon-gem.

I verified this source by doing scans of the Auction House. For example, I was able to find a large number of 8.5% crit-chance Amulets. I was not able to find ANY amulets with more than 8.5% crit-chance. I did this search without selecting a specific character (to avoid level band restrictions), and on both the Gold and Real-Money Auction House.

In all cases, the crit chance numbers they claimed were available were found in high numbers, and anything larger than that was non-existent. Please post a comment if you see an item that exceeds these ranges.

Also, these numbers reflect patch 1.0.3. The preview article for 1.0.4 suggests that 2-Handed Weapons will be getting new stat-budgets, which may change these ranges. It also mentions new Legendary Items, which may include off-slot bonuses not mentioned here.
