I liked the ability to let it freeze weapons, that made it unique while being very well element-based. Now it just seems like an Arctic Squid, that doesn't have an upkeep, deals more damage and freezes randomly. The back draw of being a weapon isn't as tough here as you also got rid of the Squid's fragility.
In case you go back to the weapon freezing, I suggest a high freezing chance (like 50%, maybe also depending on quanta amount) and ~5 | ~6 damage at a cost of 3. Immaterial weapons should be immune to freezing.
