Yeah this by no means a fully formed idea and I'd much rather discuss it and iron it out before actually throwing it at dev.

Ice dungeon type! Tundra, Mountain, Ice Cave, something like that for the name. Overworld sprite should be appropriate. Ice Cave with a recolor of the tunnel would probably be easiest. Personally, I lean toward making it Mountain for thematic reasons.

Should I leave mechanical stuff up to dev and just hand him this clump of ideas to do with as he pleases or should I work on giving them abilities and such.

Mob ideas
Frostbite Spider, a fast and physically tough mob.
Rime-blue Wyrm, a bulky flying mob resembling a dragon.
Goliath, a hulking humanoid looking like a yeti or ice golem.
Visage, a small, but moderately tough humanoid that summons creatures (undead? new ice youkai mobs?) to attack, though it has piss poor damage output on it's own. Maaaaybe debuff capabilities?

Boss idea
Snow Cap, a massive turtle-like creature covered in thick ice.

A lunge attack to move a short (long?) distance and damage/knock out of the way players in the path?
A slam of AoE ice damage.
Passively creates ice tiles on it's space and all adjacent spaces including while moving?
Possibly inflict Slow when it deals damage.

Second phase the shell breaks and it gets very fast and mean? Automatic Expanding Ice each turn (as the verglas skill)?
