About Omni-Mobs

From Modrinth

Adds some random and powerful mobs into Minecraft for overpowered mob battles.

A purple Minecraft title that says "OMNI-MOBS".

Omni-Mobs adds some powerful and overpowered mobs into Minecraft for mob battles.


  • As of version 0.1.3, no additional mods are required.
  • You can disable music, camera shake, and the coremod, in the config. Disable the coremod if you have problems with launching the game. (It should be okay now though.) Coremod is used for:
  • Metapotent Flashfur's enhanced defence.
  • Defence against Mixins.
  • getHealth() modification defence.
  • Flashfur's getHealth()-modification.
  • The mod currently does not work on servers. LAN might work, but it isn't tested often.
  • <font color="red">This mod is still in alpha. There may be bugs, and anything might be changed at any point!</font>

Mobs

Common Boss Entity Features

"Boss Entities" (BossEntity) refer to every mob except Metapotent Flashfur. They are still normal entities, but they override many core game systems.

This Includes:

  • "Absolute" Defences: While they can't be truly absolute, Boss entity defences are immune to DATA_HEALTH_ID setting, setter-method invoking, and field/EntityDataAccessor traversal, as well as some other things.
  • Immunity Bypassing: Boss entities bypass conventional defences such as damage caps and custom health.
  • Set-Target Immunity: Boss entities cannot be forced to switch targets.
  • TP Immunity: Boss entities are immune to /tp, teleportTo(), setPos(), and setPosRaw().
  • Despawn Immunity: Boss entities are immune to being removed from existence by methods such as discard(), remove(), setRemoved(), levelCallback.onRemove(), EntitySection.remove(), etc.
  • Other Random Immunities: Boss entities are also immune to getNavigation.stop(), freezing, setNoAI(), setNoGravity(), potion effects, and much, much more.

<font color="#0086FF">Flashfur</font>

Flashfur is sitting in the plains biome. There is a dark oak forest and an extreme hills biome in the background.

Appearance:

A black and white cat with blue eyes. He wears blue clothes, and is twice the size of a normal Minecraft cat.

Powers/Stats:

  • Supernatural Condition: Flashfur is far faster, stronger, etc, than a normal cat.
  • Health: 750.
  • Damage Reduction: 95%.
  • Damage Cap: 2% max health (15).
  • getHealth() Modification: An additional 5% of his damage will be a getHealth() delta - this means it adds a value into the return of other mod's getHealth() methods to change the final value.
  • Invulnerability Detection: Bans healing and erases entities if invulnerable or not taking much damage.
  • Anti-Respawn: If an entity tries to respawn while Flashfur is attacking, it will be cancelled.
  • I-Frames: 10 ticks.
  • Weak Damage Negation: ~0.02667% max health (0.2).
  • Regeneration: 0.01333333% max health (1) health per second.
  • setDeltaMovement() Resistance: 100% (immune).

Offence Moves:

  • Swipe: Flashfur will swipe at his target, dealing 75 + 10% max health damage to entities in a 1.5-block radius. He can do this many times a second.
  • Ground Slam (Shockwave Generation): Flashfur will slam his paws on the ground, creating a massive explosion that deals 1,500 + 50% max health damage, and affecting entities in a 1,500-block radius, getting weaker by distance.
  • Super-Speed-Slashes: Flashfur will fling entities into the air, and will slash them every tick (1/20th of a second) for 100 ticks, each slash dealing 5 + 1% max health damage. During the 100 ticks, entities cannot move, and Flashfur is invisible (to simulate the fact he is moving so fast, you cannot see him).
  • Supernatural Speed: Flashfur will run towards his target, reaching them instantly. Entities caught in the speed trail will be swiped, and are flinged into the air. He will sometimes do this a bunch of times in a row.

Defence Moves:

  • Parry: Flashfur will parry 80% of attacks.
  • Dodge: Flashfur will dodge 80% of damage if he didn't parry it (any type).
  • Jump Dodge: Flashfur will sometimes dodge damage by jumping out of the way.
  • Rolling Dodge: Flashfur will sometimes dodge damage by rolling out of the way.
  • Backflip Dodge: Flashfur will sometimes dodge damage by backflipping away.

Other:

  • Sometimes Flashfur will sit down, when not attacking anything.

<font color="#7100E7">Metapotent Flashfur</font> Metapotent Flashfur is standing in the plains biome. There is a dark oak forest and an extreme hills biome in the background.

Appearance:

Flashfur just looks like his normal self, but he is 10 times larger, he has moving purple and ice-blue lines on him, and he has purple and ice-blue light rays coming off him. He also has stars around him.
