"This Legendary wizard slows down enemy defenses with destructive shards of ice!"
The Ice Wizard was the third gift the players get in the "3 days of Clashmas" event occurring in the time period around Christmas 2016, with the Santa's Surprise returning as the first gift and the Freeze Trap as the second. It was available from UTC 10:00 12/30/16 through UTC 10:00 1/6/17.
It returned as a temporary troop in December 2017, available to use until January 3rd, 2018.
Unlike the Clash Royale counterpart, the Ice Wizards prioritize defenses, so they're basically incapable of taking out defending Barbarian King, Archer Queen, Clan Castle Troops or Skeleton Trap Skeletons, unless they are positioned very close to a defense that the Ice Wizard is targeting.
As the only ranged unit to prioritize defenses, they can shoot over Walls to take out defenses. Place them behind meat shields such as Golems and Giants, as both meat shields also prioritize defenses.
You could have a maximum of 65 Ice Wizards at one time in a complete set of fully upgraded Army Camps. This number increases to 80 if you include the 10 that could fit into a fully upgraded Clan Castle. On the battlefield, you could clone an additional 20 Ice Wizards with two fully upgraded Clone Spells.
The Ice Wizard can't be donated, due to being temporary.
The Ice Wizard is the third troop and the first temporary one to be directly transferred from one of Supercell's other games, Clash Royale.
The word "Legendary" in the description could refer to the Legendary rarity of the Clash Royale Ice Wizard. However, the word "Legendary" doesn't appear in the Clash of Clans Miner's or Lava Hound's description.
The Ice Wizard can't be upgraded in the Laboratory, but automatically gets "upgraded" when the Town Hall is upgraded, due to being temporary. At Town Hall level n, the Ice Wizard has $ 2*(7n+23) $ hitpoints and DPS, while each hit does $ 3*(7n+23) $ damage.
At the same Town Hall level, three hits from the Ice Wizards do the same damage as the Santa's Surprise.
At Town Hall 5-7, the Ice Wizard's DPS and hitpoints are both higher than those of their Wizard's. Also, at Town Hall 11, the Ice Wizard's DPS ties with the Wizard while hitpoints are still higher than the Wizard.
There was a mini-achievement during the limited time period of the Ice Wizard. Players needed to win at least three multiplayer battles, each with at least one fifth of total Army Camp housing space being Ice Wizards, to claim 300 Experience and 30 Gems.
After the Ice Wizard became unavailable to train, anyone who had trained the troop but had not used it would still have it in their Army Camp, at least until the October 2018 update, when all such temporary troops disappeared after their period ended.
