NOTE: Although a sentinel CANNOT build it's own stacks of [Galvanized Chamber] or Aptitude, if you carry any RIFLE and get kills yourself the stacks of Galvanized Aptitude and Chamber are carried over to the sentinel. You can use this if you want to absolutely min-max verglas DPS. Swap Serration for Galvanized Aptitude and Heavy Caliber for Primed Bane to min-max damage.

Flexible options:
[Primed Fast Hands] allows faster reload and more uptime of beams
Primed Faction mods helps min max damage against specific factions e.g. if you plan on an endurancee run and want to use [Verglas] for a specific meme.
[Vile Acceleration] is flexible over [Primed Shred] if you don't own [Primed Shred]
