Polar's Mad Tweaks

Non-undead mobs that are capable of being affected by Regeneration effect will slowly heal if they're not targeting or in combat.

Sleeping will slowly heal mobs/players.

Blindness will reduce mob's detection range much like Invisibility. Applying to an aggressive mob can de-aggro them.

Strength effect increases projectile damage, if said projectile deals damage in the first place.

Mobs with Hunger Effect will periodically take hunger damage, since they don't have a hunger meter. Applying Saturation effect on them will remove Hunger effect.

Mobs that have less or equal to 100 max health will flee from the Warden.

Punching with a fish on main hand will knock back target by a lot.

Being 3 blocks around lava will set entities on fire due to convection.

Ranged Bow/Crossbow Mobs can run out of arrows. Once run out, they will lose their Bow/Crossbow and go into Melee and will not drop arrows upon death. Except Pillagers, because they have doo doo brain. Amount of arrows they get upon spawning is configurable if this tweak is enabled. Doesn't affect boss mobs.

Cows and Goats are no longer affected by any effects that are curable with Milk. Now, they no longer guide others to a treasure they cannot possess, for they realized that they are the treasure.

Cows on fire have an 11% chance, by default, of exploding, without damaging blocks, due to emitting methane gas.

Livestock animals (Chickens, Cows, Pigs and Sheep) can retaliate against mobs/players that attack them. Nearby livestock of the same type will also attack like ZPiglins. The latter can be disabled from the former.

A random Livestock animal will attack the player unprovoked because ijfioeanfiaohfai.

Chickens that were part of chicken jockeys will be aggressive towards players.

If a Horse is killed by a Zombie, it transforms into a Zombie Horse.

Zombie Horses will turn into Skeleton Horse after a long period.

Polar Bears attack everything that isn't them and Creepers because they hate everything in real life.

Untamed Wolves will attack Zombies for that sweet rotten flesh.

Naming a wolf "Princess" or "Cupcake" will cause them to be hostile towards children.

Untamed Cats will attack anything that's smaller than them but not babies or themselves.

Frogs will take damage and be set on fire after eating a Magma Cube since they're not usually fire-proof.

Blazes heal when in Fire block or attacked by Fire attacks (Like in Dumgeoms). They will seek out any fire blocks and stand on it when injured.

Blazes can no longer get Poison, Wither, Hunger, Saturation or Regeneration as the player lacks the inhuman mind to poison or wither away fire.

Blaze's melee attack sets targets on fire because they're made of fire.

Blazes become dimmer the lower their health.

Creepers will follow any nearby baby mobs... because they're creeps.

Creeper explosions don't damage blocks.

Creepers will never attack non-player entities.

Creepers take extra damage from fire attacks, cause they green and leafy.

Creepers have an 11% chance, by default, of igniting if on fire.

Did you know that there are plants and vines called creepers that grow around other plants and/or up walls and trees. That's why Creepers can now climb on walls like Spiders! :D

Enderman holding TNT will set it off if they're on fire long enough.

Endermen are no longer racist only against players and will now attack any mob, that's not another Enderman or wearing a Carved Pumpkin on their head, that stares at their eyes.

Golems and Shulkers can't get Poison, Wither, Regeneration, Hunger and Saturation. They got no organic organs. except Shulkers probably, they don't get effect cause pfffttt.

Iron Golems take 1/10th of damage from all non-armor penetrative sources, but take extra damage from Pickaxes. The faster the Pickaxe mines an Iron Block, the greater damage.

Snow Golems takes extra damage from Shovels. They take regular damage from other sources cause they suck made of snow.

After a successful raid against those peace-loving Villagers, all the celebrating remaining raiders will EXPLODE with as big of a radius as the Wither's initial explosion. Why? To make the Village looked actually destroyed and because it's funny.

Patrol Leaders will constantly have Resistance III and Strength.

Magma Cubes sets surroundings on fire if they're medium or huge size. They made of magma, magma burn.

Magma Cubes sets targets on fire, with duration depending on size.

Magma Cubes can no longer get Poison, Wither, Hunger, Saturation or Regeneration as the player doesn't have the mind of a god to make magma hungry.

Magma Cubes will turn into a Cobbled version of itself when in contact with water. In this state, they cannot move nor deal damage, and will die if falling high enough in water, or hit by a pickaxe.

Big Magma Cubes can be stood on, and cannot be pushed.

Ghasts will periodically drop a Ghast Tear similar to Chickens laying eggs. (Coincidence?!?! 🔺👁🔺)

Ghasts are now actually incorporeal as Mojang keeps describing them.

Wardens will periodically heal when standing on a Sculk block.

Wardens will heal the amount of experience dropped by an entity it kills.

Warden attacks are AOE.

Illagers and Zombies hate each other 😠

Zombies will turn into Skeletons, after a long period since their flesh be rotting.

Zombies will turn into Husks if they either suffocate in Sand blocks or burnt to death on a desert biome's surface.

If a Drowned is out of water, and rain, and is in a hot biome, they will convert into regular Zombies after a short amount of time.

Drowned will instantly extinguish themselves from fire as they are constantly wet.
