Ice Season 22 is now underway. I guess this explains why the Iceboard hasn’t returned. Nothing but the loot has changed. We need to get 1,000 ices in 7 days to fully master it at the highest level. If you get 150 ices per day for Family Progression, you should have no troubles.
For review, each time you ice a target you get 1 ice. Kills count as 2 ices and you can’t ice the same target more than 50 times for the duration of the event. the Bully Throttle will activate. Ices to a specific target which are gained while the Bully Throttle is active still count towards your profile statistics and Family Progression.
Ice Season tier mastery does not grant you a badge or loot item until the season is over so don’t freak out if you don’t see the reward in your inventory. At the end, you will get the badge for whatever tier you are on and a Rotator Shotty for whatever tier you fully mastered. The stats of this item on each level are shown below. This item was added to the inventory on January 25th  and the stats were improved not very long ago. The Diamond Level Rotator Shotty is the highest we have seen in as a Ice Season reward and it's awesome that the attack stat is over 200!
Along the way, you get small rewards for reaching ice milestones. If you see a skill or reward point slide across your screen, don’t think you are beating the system with a glitch. It’s just one of these rewards.
