Idea Elsa, The Ice Princess

Elsa, The Ice Princess
For the latest developments of this class idea, please go to https://www.brawl.com/threads/74412/. Thank you. I have made the second thread to appeal to more people by removing the references to Elsa, though I wish for the Elsa names to be implemented.
Elsa’s armour is quite strong, but she has zero steak. Her only sustain is her healing ice chamber, making this a kill***** class. Besides healing, the ice chamber has a large array of different uses for the players to explore. She is bound to take a bunch of fall damage from using Frostwalker, though it is reduced by the Protection on the armour? Her snowballs serve as a way for preventing enemies from passing her. She can use Frostwalker to take shortcuts and catch up to fleeing enemies.

Starting Items
Golden Helmet (Crown)
Light Blue Leather Chestplate (Dress)
Light Blue Leather Leggings (Dress)
Silver Leather Boots (Slippers)
Let’s just slap Prot III on all of it.

Iron Sword (Ice Shard)
32 Snowballs (Ice Balls)
1 Snowman egg (Olaf)
64 Ice (Frostwalker)
1 Packed Ice (Conceal, Don’t feel)

Let it snow!
Snowballs thrown by Elsa and her snowmen slow and deal 1 heart.

Do you want to build a snowman?
Elsa has one snowman egg to start with, and another egg will be generated every 15 seconds. Elsa may only have 5 snowman eggs at most. Walking into spawn will kill all snowmen.

Frostwalker
While holding the ice, Frostwalker is enabled. When moving on ground (i.e. not falling, jumping, or flying), any non-solid block within a radius of 2 around the block being moved to will be turned into ice. The ice will melt quickly, similar to frosted ice in sunlight. Elsa is given a stack of 64 ice. 6 ice is consumed per second.

Extra information
Basically the Frostwalker enchantment but also on air and lava etc. Walking on lava could spawn obsidian instead of ice, that melts in the same way.
Frostwalker only works horizontally, an ice staircase is not supposed to be possible.

The ice depletion (speed) is the same as for a (sprinting) ninja.

Conceal, Don’t feel
Elsa has 1 Packed Ice. Right clicking it or taking fatal damage encases Elsa in an ice chamber for a brief duration. She is granted Regeneration V for a short duration. The packed ice will regenerate in 25 seconds, the XP bar functioning as a timer. Upon killing an enemy, Elsa gains 1 packed ice. Maximum of 1 packed ice at a time.

Extra information
Both the ice chamber and healing are basically copied from mage, with the same durations.
The regeneration mechanic is the same as assassin’s.
After being attacked by a ninja, Elsa has a free reset.
This is my favorite of Elsa’s abilities, it has so much potential.
