About Omni-Mobs
From ModrinthAdds some random and powerful mobs into Minecraft for overpowered mob battles.
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.

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 toDATA_HEALTH_IDsetting, setter-method invoking, and field/EntityDataAccessortraversal, 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(), andsetPosRaw(). - 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.

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 agetHealth()delta - this means it adds a value into the return of other mod'sgetHealth()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.

- 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).
