Enraged Mobs!

This mod gives a bunch of common mobs an enrage mechanic, which are triggered under certain conditions and make the mob stronger if ever. I made sure they aren't easy to trigger when playing normally.

This feature was originally for Mob AI Tweaks but it was scrapped due to balancing issues, so I made it a new, separate mod to not let the idea go to waste.

When a mob is enraged, they will emit particles on trigger and passively. They usually default to thunder clouds and black smoke respectively, but some mobs have differing visual effects.

Mob enrages aren't permanent, however. They last a fixed amount of time based on the mob. Upon calming down, they will emit green star particles to indicate that they have calmed down. Though, damaging them while they are enraged will reset the enrage duration.

Skeletons

-Skeletons can be enraged by using projectile attacks on them within a 16-24 block radius.

-When enraged, they will rapidly shoot arrows while walking towards their target. They also gain a temporary follow range boost.

-Their enrage lasts for 15 seconds.

Wither Skeletons

-Wither skeletons are enraged the same way as regular skeletons.

-When enraged, they will shoot out a weak wither skull every 6 seconds (4 seconds on hard). If they are using a bow, the skull cooldown is paused every time they pull their bow (in addition to using the same enrage as their normal counterpart if ever using a bow).

-Their enrage lasts for 15 seconds like their normal counterpart.

Pillagers

-Pillagers can be enraged by blocking 5 arrows shot by them with a shield.

-When enraged, pillagers will throw away their crossbow and pull out a stone axe.

-Their enrage lasts for 45 seconds.

Blazes

-Blazes can be enraged by using projectile attacks on them from more than 32 blocks away.

-When enraged, their attack cooldown and charge up time are halved. They also have a unique enrage visual since they emit a lot of particles which would make it hard to tell if they are enraged or not.

-Their enrage lasts for 15 seconds.

Breezes

-Breezes can be enraged by reflecting their wind charge back at them from more than 6 blocks away.

-When enraged, they jump around very fast and shoot while mid-air as supposed to when they are grounded. Additionally, they do a wind charge explosion on death. Their enrage particles are white smoke particles rather than black.

-Their enrage lasts for 15 seconds.

Guardians

-Both Guardians and Elder Guardians can be enraged by landing any projectile attack on them from more than 6 blocks away while they are beaming you underwater. I know the condition sounds odd but it's because attacking them with projectiles from that range underwater is normally not doable.

-When enraged, their beams charge twice as fast and explode upon finishing.

-Their enrage lasts for 45 seconds.

Creepers

-Creepers can be enraged by "edging" their explosion twice. This would rarely ever happen anyways since you either outrun the creeper or kill them before having this happen.

-When enraged, they can continuously walk while detonating. Additionally, their explosions can no longer be cancelled.

-Their enrage lasts for 5 seconds.

Shulkers

-Shulkers can be enraged by forcing them to teleport twice. This would rarely ever happen because their teleports are only forced by 25% chance when attacked. Them teleporting when the block they are attached to is broken do not count for this.

-When enraged, they shoot twice as fast and hide inside their shells more quickly. Their enrage particles are replace with the same particles end rods emit.

-Their enrage lasts for 45 seconds.

Mobs that cannot enrage and will never be given one

-Zombies (due to Mojank code, giving zombies an enrage break Zombified Piglin AI horribly and I do not know how to fix it)

-Neutral mobs (they already have one in vanilla)

-The Warden (they already have one in vanilla)

-Passive mobs

-Bosses and minibosses (see Boss AI Tweaks)

Miscellaneous Additions

-Adds "Enraged mobs stay enraged (permanentEnrage)" gamerule, which causes mobs to stay enraged forever until they kill their target. False by default.

-Adds "Berserk percentage (mobEnrageOnHealthPercent)" gamerule, which defines if a mob should enrage when hit below a certain health threshold. 0% by default, which means never.

Compatibility

There shouldn't be much issues other than balancing (hence why this was never added to Mob AI Tweaks to begin with)

Also, all enrageable mobs reuse the AngerTime and AngryAt fields for NBT data saving and loading.
