For example, here's a mob from the new Icikle family, which will have its own level 90 dungeon (according to the key that they drop):
So what I have seen so far are:
Normal: 4- lvl 75 (water/air), lvl 78 (water), lvl 82 (water/earth), and lvl 85 (water/earth).
Bosses: 2 - lvl 95 (water) and lvl 95 (water/earth)
Normal: 4 Polar Cracklers- lvl 102 (water/earth) lvl 105 (water/air) lvl 108 (water) and lvl 110 (water/earth)
Boss: lvl 120 (all elements)
You can see the sets and items on the creatures, but shows no levels or stats. The bosses drop a different set than the normal mobs. The Pumglagla (lvl 95) is probably a subboss since it drops only one equipment item which is a ring.
So far there are 4 sets from only 2 families out of a minimum of 6 families (due to there being three zones with multiply families).
Just from looking around, it seems like there are three completely different areas with their own clan members: Chillberg Ice Floe, Snowbound Snowbound Village, and Harebourg Tower, with the following monster families.
Polar Cracklers: level 102-110 (dungeon: Hagen Daz's Pot)
Northern Chafers: level 105-115 (dungeon: Missiz Freezz's Manor)
Mekas: level 110-120 (dungeon: The Frozen Tower)
Brrblis: level 75-82 (dungeon: Brrbli Dungeon)
Snow Boowolves: level 90-100 (dungeon: Niche du Yech'Ti'Wawa/Boohemoth Dungeon)
Each of the mekas gets its likeness from an already existing mob. The one shown is probably the lowest level one, the tree meka. There are also crobak and sinistro mekas.
I would find it funny if Wakfu makes the Count Harebourg Set a pure earth set and Miss Freezz an earth set with a minor elements (fire/water) like they are doing in the Frigost III expansion for Dofus.
I was surprised Dofus made Count Harebourg a pure Earth set. That was a major shock. So nothing would surprise me now with Wakfu.
