About this Mod
A data-driven cosmetic leveling system.
Tier Tower adds chat badge and nameplate cosmetics that players can unlock by sacrificing items.
Several new decorative blocks are also added.
- Drop items into a Vortex to sacrifice them and gain eminence. (EMI integration shows valid items.)
- Jump down into a Vortex to sacrifice your current eminence to prestige, speeding up future leveling.
- The Vortex is uncraftable by default since servers may want to restrict it to certain areas.
- The Obelisk display's offset can be set by using an Obelisk item on the top, bottom, or sides of the front face of the block.

Datapack Format
Overview
Tier Tower is based around sequences of tiers, with progression based on custom mathematical formulae.
The sequence tier_tower:main is special, as players will start at tier 0 of this sequence.
Other sequences can be created and assigned to players using commands or through sequence progression.
Prestige System
Players acquire prestige points per-sequence, according to the prestige_value_function defined in the sequence JSON.
When a player prestiges, their prestige points increase by this amount.
The prestige multiplier is then recalculated using the prestige_multiplier_function, which affects future leveling costs.
Sequence Format
// data/tier_tower/tier_tower/sequence/main.json
{
// if the first tier doesn't specify a base leveling cost, this value is used instead
"default_base_leveling_cost": 1,
/*
The prestige value function determines the incremental prestige points gained when prestiging.
Available variables:
- points: the total points in the current sequence
- tier: the (0-based) index of the current tier
- level: the (0-based) index of the current level within the current tier
- level_points: the number of points within the current level
*/
"prestige_value_function": "(points - 5000.0)",
/*
The prestige multiplier function determines the maximum multiplier applied during leveling.
The actual multiplier for each item will be a random value between 1.0 and this value.
Available variables:
- prestige_points: the total accumulated prestige points in the current sequence
*/
"prestige_multiplier_function": "min(8.0, (1.0 + (prestige_points / 5000.0)))",
// the tiers that must be progressed through, in order
"tiers": [
"minecraft:copper",
/* ... */
"minecraft:netherite"
],
// optional next sequence to switch to after completing this one
"next_sequence": "tier_tower:example"
}
Tier Format
// data/minecraft/tier_tower/tier/netherite.json
{
// the number of levels in this tier that must be completed to reach the next tier
"level_count": 10,
/*
The leveling cost for level index 0 in this tier.
Available variables:
- prev: the hypothetical leveling cost of the one beyond the highest level in the previous tier, or `default_base_leveling_cost` if this is the first tier
*/
"base_leveling_cost": "(prev * 0.75)",
/*
The leveling cost for the remaining levels in this tier.
Available variables:
- levels: the value of `level_count`, provided for convenience
- base: the computed value of `base_leveling_cost`
- prev: the leveling cost of the previous level in this tier
- level: the index of the level for which the cost is being computed
*/
"leveling_cost_function": "((((5.0 * level) + 610.0) * 32.0) + base)",
// optional: eminence points will be lost over time while in this tier (useful for making an 'infinite' highest tier)
"erosion_rate": {
// the number eminence points lost per interval
"loss": 1,
// the number of ticks between each erosion event
"interval": 20,
},
}
Expression Language
Formulae can be written with standard mathematical operators (+, -, *, /, ^), parentheses for grouping, and the following functions:
min(a, b, ...): returns the minimum of the argumentsmax(a, b, ...): returns the maximum of the argumentssqrt(x): returns the square root ofxlog(x): returns the natural logarithm ofxexp(x): returns e raised to the power ofxe(): returns the value of e (2.71828...)pow(x, y): returnsxraised to the power ofyabs(x): returns the absolute value ofxfloor(x): returns the largest integer less than or equal toxceil(x): returns the smallest integer greater than or equal toxround(x): returns the nearest integer toxpi(): returns the value of π (3.14159...)sin(x),cos(x),tan(x): trigonometric functions (x in radians)
Resourcepack Format
In addition to the datapack entry, several textures must be provided.
We will use the tier minecraft:copper for example paths.
Badge Texture
assets/minecraft/textures/tier_tower/badge/copper.png provides the chat badge.
// assets/minecraft/textures/tier_tower/badge/copper.png.mcmeta
{
"tier_tower:chat_badge": {
// the color used for level numbering on the badge
"text_color": {
"r": 236,
"g": 221,
"b": 255
}
}
}
Frame Texture
assets/minecraft/textures/tier_tower/frame/copper.png provides the nameplate frame.
It is made up of three 16x16 sections, that are aligned horizontally to the left side, center, and right side of the nameplate respectively.
Obelisk Texture
assets/minecraft/textures/tier_tower/obelisk/copper.png provides the outline texture for the Obelisk.
Tower Texture
assets/minecraft/textures/tier_tower/tower/copper.png provides the tower slice texture used in the Obelisk progress display.

Tier Tower server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20.1). You can switch loaders with one click in the panel.
Is Tier Tower compatible with fabric?
Tier Tower officially supports fabric for Minecraft 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Tier Tower – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Tier Tower consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
