Short and sweet. Pillar of Ice from the Seasonal Artifact should be added as a fragment. Along with a fragment that gives you Stasis Surge for Stasis weapons when you Shatter Frozen enemies. There isn't a single fragment or aspect that synergizes with Stasis weapons and it's time we get one.

And add a slot for more fragments. Stasis is wildly underpowered compared to everything except the meme arc dream.
