Mobs:

Breacher
Amongst the strongest creatures one can face on their first night firmly stands Breacher. An undead battering ram of a beast, it possesses an enormous reach and knockback, its attacks destroy weaker blocks at its front and blocking the hit with a shield will disable the latter for 4 seconds. But despair not, for Breacher can only attack once in every 3 full seconds! Plenty of time to deal damage... Or run away in terror! Just be mindful of your cover and try not to stand too clost to the walls...

Dragger
A powerful early-game mob: Dragger, a humanoid arachnid! Its long limbs give it a slight edge when it comes to reach, but its main feature is a special web snare attack that disrupts movement and, well, does the thing in the mob's name. I won't recommend pillaring up against hordes of mobs when Dragger is around.

Wrought
Be wary of the deepslate caverns: some of its denizens will see your trespassing as a challenge to a duel.
The Deepslate knight lizard, the twinblade brute! Wroughts are large and slow, but they wear their 120 HP with pride, and their claws inflict catastrophic blows, briefly disabling the player's shield and dealing a whopping 30 damage! The shield-like left arm of a Whought is frequently used to block ALL incoming damage for a brief time! Avoid waiting for the shield to go down by standing right in front of it however, or you're gonna be met with a powerful shield bash! Wrough can block only 4 times in a row. After fourth block, it will go on a randomized cooldown. Slaying this beast in early game may prove a challenge, but the scales it drops can be used to craft a new powerful mid-game alloy of great durability!

Bowlder
In the wake of the Wither's fall, a forgotten kin of the Blaze has re-emerged in the depths of the Overworld's caves. Bowlder is a formidable foe, fast and powerful; striking its opponents in close combat with large stone pillars in various combinations, inflicting a stacking Armor Crumbling debuff that reduces both Armor and Armor Toughness, and sending the unfortunate target flying. Defeating a Bowlder isn't an easy task even with advanced gear, for it has a 60% damage reduction and is completely immune to arrows! But there's a trick one could use: using a Pickaxe to fight Bowlder will bypass its damage reduction, giving you a much needed upper hand!

Tunnel Gore
Inside the tunnels too smooth to be natural, the walls are covered with the strange deepslate harboring ores of unusual yeild. Be swift as you collect them, for in the depths of the caves, you are not the only one digging.
In the deepest parts of the caves dwells Tunnel Gore, the source of the haunting sounds of the caverns, ever watchful of the tunnel it resides in. If one finds themselves in one of those tunnels, adorned with ores normal and rich, they must heed the warnings and the signs: the unnaturally dark deepslate, the cracking of the stone, the familiar underground sounds now feeling closer, and the two glowing dots at the furthest end of the cave. Should you mine too much in these tunnels or stay in there for too long, the darkness itself will come after you. Your only hope is to escape the tunnel in time.
This monstrosity is capable of crushing any block the player can get their hands on... Except netherite. Upon charging into the netherite block, an otherwise impervious Tunnel Gore will hurt itself and go back to its invulnerable lair. Make it charge into the netherite block 3 times, and the rewards of its lair will be yours!

Rager, Sorcerer and Carnager - the pillager trio!
Ragers are a new breed of Illager war beasts. Small, fast and skittish, they have low HP and deal miniscule damage... Until they taste blood. Upon hitting the Villager, this mob will enrage, becoming both faster and stronger, which, coupled with their numbers in raids, can pose a threat! Despite their hunting abilities, Ragers, however, understand that they don't stand a chance against mighty Iron Golems, fleeing from them in fear. Despite not being a good fighters, Ragers, if ignored, will speed and flee their way into achieving their main task - silently and efficiently cutting down the village's inhabitants. Don't let them do that.
Sorcerer, however, poses more significant danger. This new type of Illager wizard will buff its allies in a large zone with one of 3 buffs: rapid healing, Speed or Strength. Get rid of the Sorcerer as fast as possible, but be mindful of its wizarding might: in close combat, Sorcerer, not being a fan of fair fights, will push you away with a gust of wind, letting his subordinates finish the job.
Carnager - A walking arsenal of the Illagers, an ultimate siege weapon! After the Player has defeated the Wither, the Illagers used its remains to discover some new techniques of monster creation, thus making a Carnager. This mountain of muscle plows through villages in a heartbeat, especially when supported by the pillager forces. A battering arm capable of destroying blocks and dealing monstrous damage, wild swinging strikes to dice every foe on its path, an occasional spawner on the shoulder summoning Ragers and a Totem of Undying strapped to Carnagers bulk, allowing a revive... All of that supported by one of the two Illager mages, - Evoker or Sorcerer, - riding the colossus in combat! Truly a marvel of a warbeast! Proud Biologers even claim that this monstrosity is capable of slaying a mighty Warden... Nobody has ever witnessed such an event, but seeing this rampaging engine of living carnage shaking entire villages to their foundations seems to be more than enough.

Serene - A grounded cousin of Allay! This spiritual mob can be uncommonly seen in Birch forests, and finding it is well worth it. Upon detecting a player nearby, Serene will grant them 5 minutes of Tranquility effect, which makes all hostile mobs in a large area around the player weaker and more lethargic! After giving the effect, the Serene will enter a 5-minute cooldown.
But that's not all! If you drop a Heart of the Sea near the Serene and step back, the mob will turn it into a new item for you - a Heart of Tranquility!
