Winter hallow

The winter hallow expansion is a command which adds a Santa boss, two structures, ice rods and a snow machine.

Obtaining
Ice rods are obtained by crafting in a celestial crafter.

Mechanics
To be used, an ice rod must be selected in the player's main hand and a snowball in his offhand. Then, the player must right click to throw the snowball. Around it, all nether blocks will be transformed in ice and snow blocks, to spread the ice hallow in the nether. The ice rod is an opposite to the nether cores.

Summoning
To summon Santa, the player must drop two cookies and a milk bucket on an armour stand placed on a quartz altar (image here soon). The armour stand will then wear Santas clothes and head, and elevate in the air. After a few seconds, he will live, drop and attack the player.

Attacks
Santa will use four attacks in a loop to try and kill the player. He will also hit the player with his gifts, which will inflict knockback.

Elves
Santa can summon a swarm of elves which will run towards the player to attack him. The elves are actually baby zombies and will have the same health and speed.

Meteor
Santa can also make a meteor fall on the head of the player. The meteor will fall fast and the player can hardly avoid it.

Lighting strike
He will also make thunder strike the player multiple times, inflicting moderate damage.

Trump's wall
Finally, Santa can bury the player in a 15×3×3 brick wall to suffocate the player. Sometimes, he can bury himself in his own wall and then die from suffocation. He will still use his attacks in the meanwhile. This bug will however be fixed in the 1.1 release.

Drops
At death, Santa drops a gift containing random items, such as emeralds, your annoying brother's head, a lump of coal, a minecart toy, poisonous potatoes, coarse dirt, steaks and Krampus' whips.

Obtaining
The ice turret can be obtained by crafting in a celestial crafter.

Placement
To be placed, the ice turret's spawn egg must be placed on the ground.

Composition
The ice turret has a snow three blocks large snow pillar and a packed ice cuboid at the top containing a snow man with 100 health. The snow golem can fire snowballs which do not inflict damage yet.
