About this Mod

The Ice Warrior

Description

Minecraft datapack that add an ice themed boss

WARNING

This datapack require a resourcepack

Require the mod launch-command

This datapack whas made using Animated Java (so if the datapack is terrible that on me)

Features

This datapack has a config wich you can access it with /function icewarrior:admin/_/config

How to start:

First of all, there is new advancements that you can follow to check everything that the datapack has to offer !

To find the boss, you will need to find the ice_guard_tower structure located in an ice_spikes biome.

NOTE

You can craft a map that will show you the structure by dropping a Woodland explorer map inside a powder_snow

cold map craft

When entering the tower you will see the ice warrior encased in ice. To release him you will need to use a lava bucket in order to melt the ice (right-click).

Boss:

  • 2 phases
  • 170 health
  • everythime you get hit his combo counter will go up, dodging an attack will reset it to 0.

First phase: The boss will attack using his ice claw

boss phase 1

Second phase: The boss will attack using his trident (activate on 50% max hp)

boss phase 2

Master: Strongest variant of the boss, can only be summoned by first defeating an enraged Ice Warrior

boss master

NOTE

The first and second phases of the boss isn't that strong, and all his attacks are dodgeable. I personally recommend to face him with a full set of diamond armor.

NOTE

You can enrage an Ice Warrior by summoning one while having an Ice Warrior Head near it on the ground

The boss cannot target/damage mobs that have the tag icew.immune.

You can summon the boss anywere in your wold using the command /function icewarrior:admin/_/summon

Or you can summon the boss encased in ice with /function icewarrior:boss_summoner/summon

Because working with vanilla mob with datapack can be an absolute nightmare, all Ice Warrior share the same target.

Other informations

Because the boss use a stray as its hitbox/health, any mod that modify stray can affect the boss and might cause issues. Hoewer I already fixed this issue for some mod, if those allowed me to blacklist the mob from getting any modification.

Also because the boss use a stray as its hitbox/health, he has some difficulty when attacking mob with wide hitbox.

You can modify:

  • items that can melt the boss ice in data/icewarrior/tags/item/can_melt_ice_room.json
  • mobs that aggro the boss in data/icewarrior/tags/entity_type/aggro_boss.json
  • entities that can be parried in data/icewarrior/tags/entity_type/can_parry.json
Knows issues
  • An issue has been found with mob battle where if you set the boss target using the Mob Enrager item, the stray that is use for the boss hitbox/health, will not reset is target and attack the mob (he deal 0 damage btw). If you want to change the boss target run this command: /execute as <entity> run function icewarrior:set_target

Problems you might encounter

Spoiler

1. The boss isn't working at all / animation are not playing

I have 0 idea what's causing this issue, but the main way to fix it is to execute these commands in order.
(which is basically disabling the datapack, reload the word, than enable it again)

/datapack disable <icewarrior datapack>

/execute positioned 0 0 0 run reload

/datapack enable <icewarrior datapack>

/execute positioned 0 0 0 run reload

2. When summoning the boss I only see prismarine_shard

That mean the resource pack need an higher priority. Go to the resource pack and make Fabric mods (on fabric) / Mod Resources (NeoForge) higher on the list. (if you are using the mod version of the datapack)

If that doesn't solve the issue, or create more issues, since other mods can affect the mod resource file.
You can download the required resource pack individually (you will found it on the datapack platform where you can download the datapack .zip file at the bottom of the page)

3. Boss instantly die when summoned

This problem can happen due to mod incompatibility, mainly mods that affect vanilla mobs.

If that happen please report the issue I will try to find the mod and fix it (if possible).
But I do not guaranteed that I will found the mod.
