Evolution: Core Ecosystem (Infection Mod)

Added:
  - The Core Harvester (iron blocks, flint, sticks, infested blocks): a tool with 8 slots that keep what it harvests fresh and a food slot that feeds it; it digs the colony's blocks at a stone pickaxe's speed (any other block as your hand) and mends with flint in an anvil. The Flint Toolhead (flint in eight iron nuggets) repairs it and gives it a diamond pickaxe's durability and digging for good.
  - Blood Resin and Strangle Vines: an Ascended Tree felled with a fed Harvester's last hit may drop them fresh straight into it; felled any other way they fall and turn into Dried Resin and Dead Vines in a second. A fresh one lasts 10 seconds in your inventory and one second anywhere unfed.
  - The BioMechanical Crafter (logs, infested blocks, a Core Shell): a 3x3 grid, a food slot and a slot for your Harvester, whose fresh resin and vines it crafts with straight from its slots. It must be fed to craft, and its food burns only while it works.
  - The Altered Bio-Sword (three Strangle Vines over Blood Resin, a sword, Blood Resin): it hits for 1 more than its sword, 0.1 more a kill up to 4 more, and every kill gives 4 durability back. Each kill may rise again for the nearest Core: a mob as a thrall, a player as an infected player (5% at first, 1% more a kill, reset to 5 or 10% when one is made).
  - The Altered Armor (three Strangle Vines, Blood Resin, an armor piece, Blood Resin, three Strangle Vines; grown in the Crafter over 2 minutes): every kill heals a tenth of it. A kill made while all of it is at full durability rolls 1 in 10, rising each time, to start strangling: it will not come off, and in 30 seconds you die into a tree. Fire on yourself, three hits from anyone's sword or axe, or a piece breaking frees you and resets the count. A full set left on the ground within 8 blocks of each other becomes a tree when it would despawn.
  - The Incubation Chest (a chest and a furnace in infested blocks): a chest's 27 slots and a food slot; fed, it keeps fresh resin and vines fresh; run out, they die inside.
  - Sun Collectors can be mined (a stone axe for the Small and Medium, an iron axe for the rest) and placed: one of yours feeds no Core, never grows or starves, and links by a visible tendril to every Crafter and Incubation Chest within 8 blocks, where food lasts four times as long and armor grows in half the time.
  - The Core Shell drops itself when mined with the phase's pickaxe: wooden in Phases 2 and 3, stone in 4, iron from 5.
  - The Subterranean Sonic Emitter (cobblestone, redstone dust, a plank, note blocks): it thumps every 2 seconds and every worm within 16 blocks turns away. Placed on the colony's ground, a Gardener comes to break it and the colony holds its placer as an attacker.
  - Every infested block drops itself when mined.
  - Hostiles are food: the units hunt hostile mobs for the Core in every phase where they feed it, zombified piglins included. From Phase 7, any mob brought to the Core is a thrall 15 times in 100 and eaten otherwise.
  - Worms: one more worm each phase from Phase 4, 8 at most; now and then a worm dives up to 10 blocks down; once its normal routes are done it eats the enclosed pockets of plain ground left inside the land.
Removed:
  - The old 3-block gap between Sun Collectors (the placing rule below replaces it).
  - The Cave Guardian's digging through blocks to reach something.
Tweaked:
  - The Guardians' armor: Hunting 5, Cave 15, Tree 25, the Heart Guardian 30.
  - A pickaxe is the Core Shell's tool at every step; the early shell keeps dirt's hardness, so a wooden pickaxe opens it as fast as dirt.
  - The Gas Mask's filter lasts 14 in-game days, 28 with Spore installed.
  - Wrapping Vines and SubCore Vines take double damage from fire; every vine keeps 16 blocks from the next; the busiest square of the land goes to one vine and the next busiest to the next.
  - A new Sun Collector is placed outside every existing collector's circle: 13 blocks from a Small, 15 from a Medium, 18 from a Large, 20 from an Extra Large, 23 from a Largest.
  - The Cave Guardian digs only to make its lair and its pit; to an alarm or a target it goes through the tunnels it already dug.
  - The units' pathing: the route-search line serves waiting units on a time budget with no wasted turn, the planner takes the next waiting unit at once after a cheap plan, a unit told "no route" tries another spot instead of standing, the back-off counts per place, blackstone and basalt count as something to build with, a unit ties a subdued mob by hand within 3 blocks, and the grove harvest takes the top log first with a Gardener building its own way up to a hanging log.
  - The Sun Collectors' cords and toes root inside the crown and the knuckles hang closed under the blades; the Large, Extra Large and Largest blades are a tenth wider. The Core Heart's roots clear the shell and rest on the ground from a knot in the trunk.
  - An arrow made from nothing (another mod's archers) is given a plain arrow so the game can save it.
