Glistening Ice

Glistening Ice is the fourth skill in 's Serenity skill branch. It increases the duration of any chill she inflicts by 6 seconds, meaning it gets 3 extra damage ticks. This applies to both Ice Discharge and Chill Attack s.

Overview
This skill will probably go unused for a while because it's in the default branch yet Summon Ice takes until level 56 to unlock. But eventually it raises the art's damage potential from 5 ticks to 8, for an increase of 1.6x, which is pretty good on an art that already does deceptively high damage.
