I'd really like to build a mixed elemental/critical bow ranger (with a huge critical multiplier and, therefore, a high critical chance): it sounds like a nice way to deal great damages. There are several passive to increase the critical multiplier, but I can't find so many to increase the critical chance, which is pretty low with the bows I've found so far (the basic critical chance is 5%).
I've also read several threads about this build on their forum, but most of them are either outdated, either heavily debated.
How can I increase my critical chance ? Gear ? Gems ? Any passives I have missed ?
Best Answer
Critical chance can not be less than 5% nor more than 95%.
The base chance for bows is 5%.
Passives
There is a full list of general critical strike passives on the wiki.
This gives a combined total of +400%
There is another list of Bow specific passives giving a further +120%
Items
Out of the different mods, the "of Incision" suffix gives the most at +38%. This can't appear on all items. however if it could then it would give 304% (only counting 8 times because of the gloves below).
The unique gloves Maligaro's Virtuosity can be used with a bow and gives +50%
Gems
There is the support gem Increased Critical Strikes which gives about +105% at level 20.
Skills
Some skills give a critical strike chance bonus. For example Elemental Hit gives a +4% for every quality%. (so +80% at max quality)
Curse
There is the curse Critical Weakness which gives +10%. However this is treated differently and added after everything else.
Final Calculation
Total Possible Crit Chance with a bow is 5% * (100% + 400% + 120% + (8*38%) + 50% + 105% + 80%) + 10% = ~73%
Or an increase of just short of 1,500%. Not that this is practical, but it covers the different ways to boost crit chance.
