Due to increasing requests, this mod has been made, to allow people to use Mob AI Tweak's boss reworks outside of the mod itself.

Do note that certain datapack things like entity type tags and NBT data additions are kept but still use the mob-ai-tweaks namespace for other mods that use it. Though, this mod's namespace is "boss_ai_tweaks" so keep that in mind when checking if this mod is enabled on your end!

The Wither

-Moveset completely reworked.

-6 Phases total.

-Blue wither skulls have homing now.

-Only regenerates health upon dealing damage to anything or when it has no target.

-Enrages upon losing 25% of its health in a single attack. When enraged, attacks 2x faster and shoots 4x faster but drops 2 nether stars on defeat.

-Removed projectile immunity entirely. Only takes 50% less damage from arrows only below 50% health.

-Reworked attack visuals. Now turns blue when about to fire a blue wither skull. The original "phase 2 shield" visual effect has been repurposed into a charging animation (since this mod removes phase 2 projectile immunity)

-Phase 1: Just hovers in place, following you if you're moving too far and away if too close.

-Phase 2: Gains a slanted slam attack, spawns a pool of harming in hard difficulty, creates a creeper-sized explosion if mob griefing is enabled. Starts below 83% health.

-Phase 3: Starts strafing around the player and begins firing blue wither skulls along side the occasional slam attacks. Starts below 66% health.

-Phase 4: Starts hovering lower and closer to the player, gains a Bedrock Wither-like dash attack. Creates a trail of explosions if mob griefing is enabled. Starts below 50% health.

-Phase 5: Dashes twice. Blue wither skulls become more common. Starts below 33% health.

-Phase 6: Chains all of the attacks continuously without stopping. Starts below 17% health.

-On death: Explodes very flashily and shoots skulls everywhere before dying for good. Also creates a shower of xp amounting to a total of 1000 xp.

Quick Full Fight Here:

Elder Guardian

-Now a proper boss instead of a generic tanky enemy variant.

-Increased health to 150 (75 hearts) and defense by 8 (4 armor). Can be edited in the config.

-Has a boss health bar now but only shows up when you start fighting it.

-Laser attack reworked to be a proper laser beam. This means it is now a straight line that deals damage continuously when touched.

-It can dash now. Dashes more frequently as health gets lower. Spawns "seeking mines" below 30% health in hard difficulty (as of right now, they're just reskinned shulker bullets that deal no damage but drain your oxygen instead).

-Is now immune to explosive damage.

-Has a death animation now.

Ender Dragon

-Enrages when losing 15% of her health in a single attack (this means beds instantly enrage her!). Attacks significantly more frequently when enraged and all of her melee attacks burn targets.

-Fireball attacks have been changed to chain fire. Shoots faster the lower her health is or when enraged. To compensate, dragon fireballs have been nerfed, the harming pools they spawn last shorter now and are significantly smaller.

-Swoop attacks are now more consistent, mimicking her pre-1.9 swoop attack. (With added particle effects)

-End crystal healing reworked, no longer heals passively. End crystals now heal her in bursts. Additionally, end crystals now emit a flashing effect to indicate how close they are to finishing healing her.

-No longer perches randomly, and is now completely invincible while flying. Instead, to get her to perch, you need to destroy the current end crystal healing once in peaceful, twice in easy, thrice in normal, and four times in hard.

-After destroying the connected crystals, she perches and DPS phase begins. She now takes far less damage to her body but far more to the head. Additionally, her projectile immunity is removed.

-While perched, she spawns significantly more dragon's breath. Additionally, said dragon's breath moves now in a conic pattern away from her and as well as deal even more damage. (Unless Enhanced AI mod is installed as that mod makes area of effect clouds spherical and this becomes very unfair to dodge)

-Last but not the least, this mod fixes a crash in vanilla caused by leaving the game as soon as she shoots a fireball.
