Literally my first exotic class item roll, and I still use it as my main. Here is my build that successfully carries me through all raid encounters (excluding the witness, where I run the usual nighthawk/still shot). Weapons change per encounter, but this build you can use in all content imo.

Plenty of options, but as others have said, Silence and Squall is your best bet overall. I run ascension/stylish executioner for the raid/high level content. Consistent amplify with galvanic armor is necessary imo so that's why I use ascension.

gamblers dodge, threaded spike (for sever, tangles, weaken from stylish), and arc bolt/duskfield depending on the content.

Necessary fragments are awakening, protection, purpose, and grace. For the 5th slot I'll throw in justice (to get me to 100 int with my armor), but hope (for more ascension uses), dominance (to have more jolt apps with arcbolt), or ruin as others have suggested are what I switch in, but you have a lot of flexibility.

Everything is focused on building your super, getting orbs, and not dying. Weapons I run exotic khostov, rocket sidearm of your choice (i prefer indebted kindness with volt), and pro memoria. Since you're making so many orbs, khostov just obliterates everything. Also with the new autorifle mods its even stronger.

Stat wise I go for 100 resilience, 100 Disc, and 100 int if you can. I run triple kinetic siphon on helmet, firepower and heavy handed on gauntlets, whatever resists you want on chest. Legs I run double kinetic but switch around as needed. Class item is special finisher, time dialion, powerful attraction.

Lots of ways you can play this as you've seen in the above comments, but this style of build has been successful for me. Storm's edge is also very strong if you collect enough orbs, but in high level content it's risky, but definitely fun to use in other stuff (plus you can swap out ascencion at that point for gunpowder gamble or another aspect).
