gear/trait DA still works normally, but only after you remove the DA you get from a weapon.
For example purposes, lets say joy, or the DA weapon your looking to use has a 50% DA rate and you have 20% DA in gear (round numbers for simplicity).
Without that DA weapon you would have a 20% DA rate, or 1/5.
WITH the 50% DA weapon, you would NOT get 50%(weapon)+20%(gear)=70% DA. Instead after 100 atks, 50 would be DA from the weapon. Remove those. Now you have 50 single hits left. Your 20% in gear will work on THOSE only. So 20% of 50 attacks is 10 DA. So when its all added up, from 100 atks, 50 are weapon DA, 10 are gear DA, total DA is 60/100 or 60%.
Basically if your weapon DA reduces your gear/trait DA by the same % as the weapons proc rate. 50% weapon DA cuts your effective DA from gear/traits by 50%. Thus why 50% weapon+20%gear/trait(halved=10%) becomes 60% overall DA rate.
RL example, i have the OAT lance for drg. (supposedly 40% proc rate). My pole grip(2%DA) is only bringing my DA rate from 40 to 41.2%. 40% OAT lance reduces that 2% grip by 40%. 0.4*0.02=0.008. so 0.02-0.008=0.012 or 1.2%. 40%OAT lance+1.2%=41.2% real DA rate.
If you ahve 24% gear and use a similar 40% OAT weapon, 0.4*0.24=0.096. .24-0.96=.144. Your 24% DA would stick on 14.4% on top of the ~40% OAT weapon=54.4% DA rate.
Probably a little more than needed to answer the question, but there it is. you can also remove a step in the math by just doing 0.25-40% (using the above example #s) but some people have trouble wrapping their head around subtracting a percentage from a percentage correctly in my experience so thus the 2step method described instead of the 1step jsut now.
Anyway, hope this answers your question.
