Features

Creature infusions

A Creature infusions page (off by default), inspired by the idea of special creatures in creature/loot difficulty mods but written from scratch. Creatures may spawn with a trait (shown by colored level stars) and/or an elemental infusion (shown by a soft glow in the element's color); the name shows both in their colors (Name · Trait · Infusion).

  • Traits: Aggressive (red, +30% damage, attacks more often), Quick (magenta, +40% speed), Regenerating (green, 2% health every 2 s), Vigilant (cyan, sees and hears 60% farther), Splitting (white, only on creatures with stars: when it dies it splits into two creatures with one star less that keep splitting, until the last ones have no star; split creatures drop nothing), Armored (blue, -35% damage taken), Vampiric (crimson, heals 30% of the damage it deals).
  • Infusions: Fire, Frost, Lightning, Poison, Spirit – hits gain 35% of their damage as the element (with the game's own effects: burning, chill, shock, poison) and the creature takes half damage from its own element; Chaos – a random element on every hit, a bit stronger, and a little resistance to all of them.
  • Trait chance, infusion chance, extra chance per star, bosses on/off (never Splitting), trait strength, infusion strength, extra health, extra loot (trophies are never multiplied), name tags, colored stars and glow – plus an on/off for every trait and every infusion.
  • Each creature is rolled once, by the client that owns it, and the result is saved in the creature's own world data, so every player sees the same creature and nothing re-rolls after a restart. Turning the page (or a single trait) off makes the creatures act as in vanilla again at once.
  • Performance: only creatures that rolled something are tracked; the damage, name and HUD hooks cost one lookup for every other creature and nothing at all while the page is off.

Stars

A Stars page under Difficulty (needs Custom difficulty on):

  • Use star table (off by default) – while it is on, a summary at the top of the page shows the current odds for creatures and bosses, today's day and how much each growth (bosses, days) adds; instead of the star chance and the minimum/maximum stars, two tables decide the stars: creatures and bosses, each with the chance of exactly 1 to 10 stars. What is left of 100% is the chance of no star (shown live under each table). A change that would push a table above 100% is refused with a red warning. The creature table starts at 9% one star / 1% two stars (about the normal game), the boss table at 0%. It applies to every creature, dungeons and camps included; creatures that already exist keep their stars; split creatures still get one star less.
  • Growth with progress (creatures only) – Increase per boss defeated (+% of the chances for each boss defeated in the world) and Increase by days (+% every N days). Both add up and multiply the star chances; the no-star chance shrinks to make room and the total never passes 100%. A preview line shows the chances in force now, e.g. Now (day 40, 3 bosses defeated, chances x1.5): no star 55% · 1★ 30% · 2★ 15%. Bosses never grow: their table is exactly what the admin sets.
  • Size per star for creatures and for bosses (0% = vanilla). Careful: big sizes can get creatures stuck in doors, caves and dungeons.
  • When the table is on, Chance of each star and the minimum/maximum stars on the Difficulty page are greyed out ("controlled by the star table").
