Guild Wars 2

My build is almost the same but instead 5 in illusions i put 5 more in dueling for the crit. 5 more in inspiration is also a good alternative.
Indeed, 5 in illusions to reduce illusion cd is not cumulative with 20% gs sword or focus reduction so it works only for 7 8 & 9 if you have illusion skills.

The bug seems to be corrected since yesterday.
I’ll try to make a step by step tonight.

I actually have on my mesmer giver’s scepter and giver’s torch (+20% condition duraion), +30% thanks to domination, +10% with Superior Rune of Lyssa and +10% with Superior Rune of Nightmare.
Adding to that +33% confusion duration with Master of Misdirection
So we have 103% on confusion duration. We eat a rare veggie pizza to obtain +40% condition duration = 143%

Confusing Images = 5s with the boons on condition duration , we reach 12,15 s but we stack at 9s
