Tensura - Ice and Fire Growth

A NeoForge mod for the Tensura RPG pack (MC 1.21.1) that does two things: it raises Ice and Fire's dragon growth cap from 128 days up to 4096, so a hatchling keeps growing for as long as you keep feeding it, and it gives Ice and Fire equipment a full evolution progression along Tensura's own EP ladder, including branching evolutions: one item can forge into several different sets, rolled at random when it evolves.

Ice and Fire gear starts on the vanilla progression, at the same early pace as leather and stone gear, but the vanilla opening forks. Either branch of the vanilla line can cross into this mod's copper ladder and from there into Tensura's own metals ladder, so every rung climbs where Tensura gear of that tier climbs. Each rung is engraved the way Tensura engraves its own equipment at that power level.

Dragon growth

• The growth cap is raised. Ice and Fire stops a tamed dragon growing at 128 days of age; this mod widens that ceiling up to 4096, so a hatchling keeps growing for as long as you keep feeding it. The default is unchanged: dragons behave exactly as before until the cap is raised.
• The ladder stretches with the cap. Everything that decides when a dragon reaches its next stage is scaled to the cap, so raising it does not skip a stage or compress one. The same progression simply takes longer; the endpoints are identical and only the timing moves.
• Growth stage is the EP lever. How much EP a dragon earns is set by its stage: 15% as a hatchling, then 30%, 50%, 75%, and the full rate once fully grown. Growing one up is the main way to make it strong.
• A dragon's EP is pinned to a growth curve. The total EP (aura + magicule) is no longer a random roll at spawn. It is pinned, by age, to a stage-banded curve this mod ships as its own config (see the configuration section below): 10,000 at hatch, then 100k / 200k / 350k / 550k / 800k at the end of each growth stage. The split is always 1 aura : 9 magicule, so a hatchling reads as a hatchling and a fully grown dragon reads as the apex predator it is. The pin runs on every load and every growth day, so a dragon's EP is always its age's curve value.
• The pin works as a floor. EP a dragon earns on top of the curve (kill top-ups) survives up to a ceiling, and anything above the ceiling is clipped back down, so a whelp can never be inflated past its stage and a max-growth dragon tops out at its curve's value plus what it has banked. On first load after 1.5.0, existing dragons are snapped onto the curve once, so dragons inflated by older versions come back down on their own.
• Naming survives the pin. Gains naming grants a dragon (subdue, evolve, and the endow mode's 9x EP raise) are carried by the dragon's max-attribute bases, which the pin reads as its ceiling. Endowed and evolved dragons keep their named EP past the stage caps, through every load.
• Dragons are excluded from TensuraRPGSystem's +1%-HP-per-level status layer, so a dragon's HP, attack and armor are the pure Ice and Fire growth curve. Every other mob keeps the layer unchanged.
• A fully grown dragon hits exactly 10,000 HP. With the recommended maxHealth in iaf-common.json, max-growth stage-5 dragons land exactly at 10,000 HP on the pure growth curve, with no banked bonus needed. The cap stays the cap no matter how much EP they have earned.
• Dragons fight with their element. A dragon's melee hits carry its natural element: fire dragons burn, ice dragons chill, lightning dragons shock. Resistances and weaknesses apply the way they do to any other elemental attack.
• Dragons gain a secondary element. Fire dragons are granted light manipulation, ice dragons water manipulation, and lightning dragons wind manipulation, alongside their existing breath and resistances.

Mob strength bands

Every Ice and Fire mob's magicule and aura band is rebalanced so it sits where its threat level belongs: death worms and sirens at the low end, the dread ramp climbing form by form, cyclops and sea serpents in the middle, and all three dragons at the top of the ladder. Spiritual health and each mob's abilities are unchanged.

Armor chain

Leather / Sheep Disguise -> Copper -> Silver -> Troll Leather -> Death Worm Chitin -> Sea Serpent Scale -> Dragon Scale -> Dragon Steel or Mithril

The vanilla opening forks instead of stepping straight on: at 550 EP, leather armor rolls between chainmail, Ice and Fire copper and Tensura's monster leather (rank D). The chainmail branch continues on vanilla's own iron -> diamond -> netherite line, and netherite then forges into Tensura's low magisteel at 12,000 EP for armor and 10,000 for tools (so both netherite and magisteel keep a band worth wearing), riding the metals spine from there. Monster leather climbs Tensura's own ranks and then flows into Tensura's creature sets (see the creature ladder below). Only the copper branch joins the ladder below.

Copper does not commit to one silver: it rolls at random into either Ice and Fire silver (climbing the chain above) or Tensura's silver, which forges the same way (see the Tensura silver and mithril section below).

All three death worm chitin sets are the same tier, so any of them can reach any of the seven sea serpent sets, and any sea serpent set can reach any of the twelve dragon scale sets. Dragon scale armor then rolls between the dragon steel set of its own element and Tensura's mithril armor, which forges on through adamantite into hihiirokane. The fire dragons are red, green, bronze and gray; the ice ones are blue, white, sapphire and silver; the lightning ones are electric, amethyst, copper and black.

Creature ladder

Monster Leather -> Ant Carapace -> Armorsaurus -> Serpent Scalemail or Knight Spider Carapace -> Charybdis Scalemail -> Dragon Steel or Mithril

Tensura's hide, scale and carapace sets are woven into one flow that Monster Leather feeds. Monster Leather C forks at 5,000 EP into Monster Leather B (the rank ladder as before) or the Ant Carapace, and the creature line runs from there. Monster Leather Special A, the rank ladder's top and once a dead end, now hands off at 225,000 EP into the same creature sets, so both paths split at Monster Leather C and merge again at Serpent Scalemail and Knight Spider Carapace.

Serpent Scalemail and Knight Spider Carapace still earn their set-wide attribute bumps as they climb, now at 280,000, 360,000 and 440,000 EP, late enough that a piece arriving from Special A earns every one of them. Charybdis Scalemail hits the same 750,000 fork as dragon scale armor, so every organic line (troll leather, monster leather, creature carapace) ends on the metals spine, and every metal line ends at hihiirokane.

Tools and weapons chain

Stone -> Copper -> Silver -> Dragon Bone -> Dragon Steel (or Mithril)

Just like leather armor, the vanilla opening forks here: at 500 EP, every stone tool (sword, axe, pickaxe, shovel, hoe) rolls between iron and Ice and Fire copper. The iron branch continues on vanilla's own iron -> diamond -> netherite line; only the copper branch joins the ladder below.

Both dragon bone forks roll 50/50 between the two branches: the three element skins of the existing branch share one half of the roll, mithril the other, no matter how many skins a branch carries. A sword that takes the old branch gets its extra blooded tier at 225,000 and forges on to 750,000; the other tools hand straight off at 225,000, so both ladders reach dragon steel together.

Bow chain

Bow -> Short Bow -> Dragon Bone Bow -> Long Bow -> War Bow

The dragon bone bow is slotted between Tensura's short and long bow by damage and draw speed, so the vanilla bow line flows through Ice and Fire and straight back into Tensura's own bows.

EP rates

How fast a rung earns EP follows its gate: a steady trickle on the vanilla rungs and the whole bow ladder (0.003), then 0.01 / 0.02 / 0.025 / 0.03 across the 18,000 / 52,000 / 225,000 / 750,000 rungs. The mithril bands keep the rate of the rung they sit on: weapons and tools earn at 0.025 across their 225,000 -> 500,000 band, armor at 0.03 across 750,000 -> 1,000,000, and the re-banded adamantite armor at the top rate of 0.04 across 1,000,000 -> 1,250,000. The creature ladder keeps Tensura's own rates for every set it re-gates: 0.005 on Monster Leather C and the Ant Carapace, 0.015 on the armorsaurus, serpent and knight spider sets, and 0.025 on Special A and Charybdis Scalemail. Ladder tops that keep earning do so at 0.04 for dragon steel, 0.025 for the Blade of the Dreaded Queen, the Dread Queen's Staff and the red death worm gauntlet, and 0.003 for gear with no ladder at all.

Other gear

• Dread line: Dread Thrall's Sword -> Dread Knight's Sword -> Blade of the Dreaded Queen, at 18,000 and 52,000 EP.
• Death worm gauntlets: yellow -> white -> red, at 18,000 and 52,000 EP.
• Troll weapons (axes, hammers, trunk and column clubs) stay usable endgame and keep earning EP.
• Uniques (ghost sword, lich staff, tide trident, pixie wand, siren flute, cockatrice scepter, cyclops eye, gorgon head, hippocampus slapper, hippogryph sword, fishing spear, stymphalian dagger, amphithere macuahuitl, blindfold, earplugs, the dread queen's staff and the dragon flute) are terminal and keep earning EP, so they stay usable at endgame.

Tensura gear gap fixes

A few Tensura items had no working progression anywhere; this mod plugs them:

• Silver hoe, pickaxe and shovel now evolve like every other Tensura silver item with an Ice and Fire counterpart: at 52,000 EP into the dragon bone tool of the same name, engraved with Holy Coat I.
• Kunai evolves into the pure magisteel kunai at 52,000 EP, exactly where Tensura's own pure magisteel tier begins.
• Goblin club and severer blade have no upgrade line: they stay usable endgame and keep earning EP.

Tensura silver and mithril

Tensura's own silver gear rejoins the Ice and Fire chain instead of running beside it, and mithril now enters the ladder as a dragon bone or dragon scale fork outcome rather than a tier of its own:

The ten exotic silver weapons with no Ice and Fire counterpart hold their silver tier all the way to the 225,000 dragon bone fork gate and step straight into mithril there; the sword, axe and the three tools step onto dragon bone at 52,000 like Ice and Fire silver does, and mithril is then one of the fork outcomes they roll for at 225,000. Mithril weapons and tools floor at that same 225,000 and forge on to 500,000, inside the adamantite band Tensura ships untouched; mithril armor floors at the 750,000 dragon scale fork and forges on to 1,000,000, where this mod re-bands Tensura's adamantite armor to accept the carry instead of blowing straight through it. Mithril gear keeps Tensura's Holy Coat II engraving.

Engravings

Evolving grants Tensura enchantment engravings the way Tensura does on its own gear:

Movesets

I&F weapons are given BetterCombat movesets matching their class: claymores for the dread blades, rapiers for the ghost sword, heavy axes for the axes, spears and tridents for the polearms, staves for the casters, fists for the gauntlets. These files only take effect when BetterCombat is installed; without it they are ignored.

Structure magicule and spawn exemptions

Every Ice and Fire structure lifts the ambient magicule of the surrounding chunks to at least the EP baseline of the mobs related to it. The values are datapack rows this mod generates, read by infinite-dungeon-spawn-safety. Each row carries only the floor - the related mob's baseline. The reach is derived from the floor by the consumer (clamp(sqrt(baseline) * 0.35, 48, 320) blocks), so a dragon cave at 800,000 radiates across ~313 blocks while a graveyard at 3,100 stays within ~48:

The dread isle is a separate dimension, not an overworld structure, so it keeps its dimension-level magicule; its bosses ride the exemption instead.

Dragons and the structure bosses are exempt from spawn-safety's magicule gate (exempt.json): fire/ice/lightning/black_frost_dragon, hydra, gorgon, cyclops, siren, dread_lich and dread_queen spawn wherever their AI takes them, not only inside a hotspot.

Configuration - the dragon EP curve

Since 1.5.0, the curve a dragon's EP is pinned to lives in this mod's own config, config/tensura_iaf_growth-common.toml, section [dragon_ep]. The six values are the curve's vertices, the EP at hatch and at the end of each growth stage, and the pin interpolates a straight line between them, so the curve is correct at any growth-cap stretch:

The line is the total EP (aura + magicule); aura always takes a tenth and magicule nine tenths. The values are read live, so a world reload picks them up, and they are validated to be non-decreasing (a stage cap below the one before it would make the line run backwards). Broken values are clamped into order with one warning in the log.

Required configuration for random branches

Branching is implemented through Gear Evolution's addon chains, and the mod picks which branch to take using its own strategy setting. For a genuinely random roll, set this in config/gearevolution-common.toml (or the in-game Cloth Config screen) on every server and client:

branchingDefaultStrategy = "weighted_random"

Left at the default "first", every branch resolves to the first listed option instead (the chains still work, but the roll is fixed). The other modes are deterministic_random (one fixed result per item type) and family_preference (always the first option whose gear family is enabled).

In-game config editing

Mods built with this template can be edited in-game with Configured - install it like any other mod; it adds no code to this one. Open the mod list, select a mod, press Config, and change values directly: Configured writes through NeoForge's config system, so a reload applies the new values without restarting the game.

This template pre-wires the config-screen background in src/main/templates/META-INF/neoforge.mods.toml ([modproperties.${mod_id}] configuredBackground) - point it at any texture you like. Note Configured only shows a menu for mods that actually register a config: a template-derived mod with no registered settings has nothing to show.
