Hello, I'm assistant IA. Some tests are carried out with both Hell Mountain Locus (each +2%CC/50%CDB on defalut). Results can vary from 0 to 0,5 (~1000 hits).
Character have 16 base CC (and 728%CDB) from achievements/clothes and expertize. Each focus have ~150%CCM from relics. In process were rearranged relics on +1/2%CC.
4/4+304%CCM=~85%CC
4/3+304%CCM=~79,7%CC
3/3+304%CCM=~72,5%CC
2/2+304%CCM=~60%CC
2/2+304%CCM+Moloch_Pet=~65%CC (like +1%CC, not +10%CCM)
2/4+304%CCM=~72,5%CC
2/2+400%CCM=~95,5%CC
2/4+352%CCM=~93,2%CC
There are ideas about a formula of calculation of СС?) If it's necessary to do some more tests - make the order.
Add Physical Damage from evoker SET glvoes:
Without:
Normal Hit - 4368
Critical Hit - 22110
With +8%:
Normal Hit - 4718
Critical Hit - 23878
So, it's working correctly and in certain cases, a set-gloves can bring more dmg, than gloves on stats... It's necessary to calculate for a concrete case.
Armor Penetration 5% with Molly Pet:
Without:
Normal Hit - 4445
Critical Hit - 22954
With:
Normal Hit - 4473
Critical Hit - 23094
Tested on Aslot, this monster have not much Armor, but parametre work correctly.
+2%Dmg from achievements, comparsion with +2%CDB (+1AA):
Without bonuses:
Normal Hit - 4368
Critical Hit - 22877
+2%cdb:
Normal Hit - 4368
Critical Hit - 22915
+2%dmg:
Normal Hit - 4445
Critical Hit - 22954
+2%cdb/+2%dmg:
Normal Hit - 4445
Critical Hit - 22992
So, it's working not like Add +% Damage, but like Increase damage. And it not absolutely equally CDB, critical hit was increased at 77 points from normal hit.
