I have several columns because I was merging data from multiple parses under the same conditions. I also had 2 different damage types on my weapons so have the swings from primary and secondary included in different columns.
I tested this using the level 92 relentless conviction as I just realized that is what I have on all my toons. It still states it increases base trigger percentage by 6%
I used a brigand ungrouped against a training dummy doing nothing but auto attacking. I had 1 ykeshan proc item on and 2 devastation strike items on
The only proc that change significantly was Interrupt. All weapon procs seemed to be essentially unaffected by it. In the case of yekesha's vengeance this was expected as it cannot be affected except by direct means but the proc rate of devastation strike is affected but actually had a slightly lower proc rate despite the expected boost. Would love to see additional tests added or a critique of the test.
