Ice Nova cooldown appears to be shared incorrectly

- One skill supported by Cast when Damage Taken
- One skill socketed in Cospri's Malice
- One skill supported by Cast on Critical Strike Support

In the above setup, triggering the first Ice Nova causes all three skills to go on cooldown.

By changing nothing except the Ice Nova gems to Vortex or Freezing Pulse gems, the cooldowns are no longer shared. Demonstration (youtube)

One melee crit in this setup cannot trigger two Ice Novas. One melee crit can trigger two Freezing Pulses, Vortexes, or Wintertide Brands.
