This is a build around the interaction between Shared Nighmare, Time parasite, Current's Rush (high tide) and Frostfall (Dispersed Suffering and Shattering Head). Against groups of enemies, this character can clean the map, leaving survivors like the shadow of themself.

Greater Focus (to enhance the Nighmare AoE)
Hammering Thoughts (damages are dealed by weapon)
Two Weapon Style (to reduce the recovery for Current's Rush)
Lingering echoes and usual CC spells
Equipement :
Thaos' Headdress (Heaven's Cacophony is great too) (+1 int +5acc vs flanked, or +2int and avenging storm for High Tide, Dispersed Suffering and Shattered Head)
Mirrorback (safer at distance)
Charm of Bones (+2int, very resistant minions)
Gloves of the Dungeon Warden (the build is around crit)
Ring of the Marksman (ranged) and Ring of Overseeing (AoE) Later, the Whispers from the Depths
Boots of the Stone (later, the Vithrack Silk Slippers can greatly make the difference for survivor enemies)
Girdle of Mortal Protection (good and cheap)
Gipon Prudensco (free move, buff to reflex and deflection)
Current's Rush (Main Hand) with upgrades and legendary, better with Mythic
Frostfall (offhand) with Dispersed Suffering and Shattering Head
In combat, the principe is to casting Borrowed Instinct and other CC spells on the most resistant enemy ; during this time, attacking at ranged distance (so only with Current's Rush) other enemies to trigger the Ascension in the first time, and High Tide with relative AoE.
High tide can proc itself High Tide on crit, and when do a kill, proc Dispersed Suffering that can proc on crit Shattering Head, that can also proc Dispersed Suffering on kill. Because of the high AoE size (Shared Nighmare, int and ring) the 4 or 5m radius of these abilities are really big and concern a lot of enemies. This is because Dispersed Suffering proc on any weapon kill, and Shattering Head on Frostfall crit (Dispersed Suffering is a Frostfall attack).
Each kill mean +20% hostile effects duration (Dispersed Suffering), and an unique first crit can do many kill with this setup. If staying enemies are under the effect of Borrowed Instinct or Time Parasite, their durations can "explode" and by the way make growing the correspondant beneficail effect on the cipher.
The Vithrack Silk Slippers, when reapplying a CC spell on enemies, do an adjustement of the duration of the affliction, but in reality when dispersed suffering proc nearby, the 20% is applied to the total duration (not current duration) so not only the duration of the spell itself but the totality of the casted spell (It is hard to be evident in english).
To illustrate this point, I made a screenshot at the tavern I try the build :
I cast only one time Secret Horror and Mental Binding before High Tide proc.
As you can see, there is many proc in the combat log, and the blood on the floor show the after-high-tide effect.
Of course, there is many way to exploit Dispersed Suffering (Berserker on skellies with Grave Calling in main hand, Ranger with mortar or the Weyc's Wand in main hand, etc) but SC Cipher seem to me the most suitable classe to make a Current's Rush/Frostfall build, combining high speed, high accuracy, high AoE size for the high tide effect.
