Enemy Expansion

1.9
The Deep-Slated Update!

Petrimen (Petriman + Petricrawler + Petriboulder)
Rocky humanoids who live exclusively in caves. Some carry carved boulders around, while others' legs have crumbled away. No matter what though, some things remain consistent: They're all remarkably sturdy, resisting ranged and burning attacks exquisitely, and they all dislike your presence in their home thoroughly. Get out!

Silverking
Overgrown bedbugs who'll leak Silverfish when hurt, ew! Using a sword against them allows you to banish their silver spawn before they even have a chance to touch the ground, so consider making the most of that! They're cowardly, and get real fast when hurt. Might want to consider investing in Bane of Arthropods after all...

Silverhats
Unfortunate Skeletons who were taken over by Silverfish mothers, who have now latched onto their heads and use them as their own personal bodyguards. Like Silverkings, they spawn Silverfish upon being hurt or killed.

Intruder
A heavy-set Creeper variant who cannot be knocked back. With an even stronger explosion and the ability to survive its own blasts to boot, stay as far away from this guy as you can. If you HAVE to get close, make the most of your shields (which won't last long if you over-use them here.)

Crawler
A lightweight Creeper variant akin to the Intruder, this guy lacks health, strength and weight, but makes up for it in speed. It's light weight proves a benefit to it, as it can use its own explosions to propell itself through the air, making it hard to catch. Be careful around this one!

Troll
What could be considered a Warden progeny, the Troll can instantly kill a completely unprotected player in a single bite. Do NOT engage with it: When aggravated, it becomes briefly invincible, and massively faster. All things considered, the most sensible thing you can do to counter a Troll is to simply leave it be.

Vampire
This regenerative bloodsucker is a tricky bugger: With the ability to steal your health should it bite you, in addition to regenerating passively, the Vampire is slim and fast, allowing it to swiftly move in and momentarily slow and blind you should it sink it's teeth into you. When hurt, it'll either continue attacking, briefly and erratically run away, or turn into the Biter, a far weaker but more unpredictable bat form. After a couple of seconds, it'll have regenerated enough to turn back into a fully healed Vampire, effectively restarting the fight. Biters are most effectively taken out by Trident throws and fully-charged axe swings, but both Vampires and Biters can also be banished by being burnt with flames, achievable with either fire-based enchantments or being right-clicked with Flint and Steel. Additionally, they'll also combust under broad daylight - Don't get caught in the blast when the sun rises!

Headbiters
A slain Biter can be worn as a Headbiter, which will heal whoever is wearing it when they take damage, leaving a lingering cloud for a short while. Skeletons in the Deepslate Caves can often be seen adorned with them. When the wearer of a headbiter is killed, they'll fly off and turn into a Vampire. Be careful if a Headbiter flees a fallen foe in the day - They might explode!

Slimeheads
Entirely unrelated to caves: Ranchers now sometimes drop Slimeheads, which when worn, causes attackers to be knocked back automatically. Zombies and Skeletons in Swamps can sometimes be seen wearing them.

- Sprinters now emit angry particles when their dizziness wears off
- Slugger's boost effect has been upped from 5 to 7
- Frigid are now labelled a Zombie variant and will despawn if accidentally spawned inside a wall
- Huntsmen now have 6 armour points and 0.42 movement speed (from 0.40)
- Fixed Meatman spawning... Again...?
- Cinder's explosions will no longer damage the environment if the mob griefing gamerule is set to false
- Goblin mobs all now use the 'Goblin' prefix in their names
- Goblin Rancher now has a new rare special drop - The Slimehead!
- All mobs now have loot tables
- Moved the Phantasm set bonus from the player's tick update to the cowl's tick update

Misc

- petrimanRandomRule (default: 1)
Petrimen will sometimes be randomly replaced by Petricrawlers and Petriboulders upon spawning. Set to 0 to disable.

Note:
Due to a workaround: Petrimen, Petricrawlers, and Petriboulders all share one spawn weight deriving from the Petriman.
When the Petriman spawns, it will randomly choose to either keep the Petriman, or swap it out for a Petricrawler or Petriboulder.
If petrimanRandomRule is disabled, Petricrawlers and Petriboulders will not naturally spawn.
