Tiered Item Modifiers

This page documents the custom item modifiers contained in the server's Tiered/Reforged datapack. These modifiers can change the stats of armor, weapons, bows, tools, shields, staffs, fishing rods, and elytra.

Quick Answer

When an eligible item receives a modifier, the system:

1. Finds every modifier pool that matches the item.
2. Selects a matching pool using the pool's relative weight.
3. Selects one modifier from that pool using the modifier's relative weight.
4. Applies the modifier only while the item is used in its configured equipment slot.
5. Allows the modifier to be rerolled with the appropriate hammer and the Anvil.

If you don't like the roll, reforging sends the item back to step 2 — a new pool and a new modifier are selected, at the cost of XP and hammer durability.

Best Modifier by Playstyle

This is a practical recommendation chart, not a strict weakest-to-strongest ranking.

How Weights Work

• Pool weight decides how often a group of modifiers is considered compared with other matching groups.
• Modifier weight decides how often an individual modifier is selected after its pool is chosen.
• A higher number means more common, not stronger.
• A weight is not a direct percentage because one item may match several pools at the same time.
• Special modded items may match both a normal equipment pool and a special item-only pool.

Main Pool Weights

Reforging

Use the Anvil to replace an item's current modifier with another valid roll.

The tables below show the configured experience cost and hammer durability cost for each modifier. Reforged describes its experience cost in XP points rather than full experience levels.

Reading the Stat Tables

• Flat additions are shown as +1, +4, and so on.
• Percentage modifiers are shown as +10% or −25%.
• 2 maximum health = 1 heart.
• 2 armor points = 1 full armor icon.
• Armor values are listed per equipped armor piece, not as a full-set total.
• Main-hand bonuses apply only while the item is held in the main hand.
• Off-hand shield bonuses apply only while the shield is in the off hand.
• Staff bonuses are configured for either hand.
• A percentage modifier on an attribute whose normal base is 0 may do nothing until another item or effect first adds that attribute.

Armor Modifiers

These modifiers can roll on equipment matched by the configured Forge or Bookshelf armor tags. Unless noted otherwise, the effect applies while the armor piece is equipped in any armor slot.

Armor Notes

• Dented I, II, and III are separate internal files even though their visible names may be similar.
• Rare and Legendary have multiple internal variants with different bonuses. Read the tooltip rather than relying on the rarity name alone.
• Heavy uses a percentage knockback-resistance bonus. Because ordinary players begin with zero knockback resistance, it is most useful when another item or effect already provides some.
• Godly, Mythic, and the Angel special include some bonuses configured for MAINHAND. Those specific lines only activate while the armor item itself is held, not while it is worn.
• Tectonic Crest Special contains −50% spell cooldown reduction. A negative reduction normally makes spell cooldown behavior worse rather than better.

Special Armor-Set Modifiers

These are only added by item-specific pools. The listed items may also match ordinary armor pools, so the special modifier is not necessarily the only possible result.

Melee Weapon Modifiers

These modifiers are intended for swords, axes, Forge-tagged melee weapons, compatible Blue Skies weapons, and selected Sons of Sins weapons. Simply Swords unique weapons also receive their own positive-only pool.

Melee Notes

• Berserk now grants a very large +75% attack-damage bonus, +2 critical bonus damage, and +55% to existing critical rate, but still reduces attack speed by 25%. It no longer reduces block or entity reach.
• Berserk’s critical-rate bonus is multiplicative, so it increases an existing critical-rate value by 55% rather than adding 55 percentage points.
• Critical sacrifices 10% normal attack damage for +2 critical bonus damage and 25 percentage points of critical-hit chance.
• Arcane and Mythic include Better Paragliders two-handed stamina attributes.
• A separate melee_weapons/extended file exists with +1 block reach and +2 FTB Ultimine maximum blocks, but no pool currently references it. The active version used by the shared tools-and-weapons pool is tools/extended.

Bow Modifiers

General bows matched by the Forge bow tags use the following modifiers.

Too Many Bows Modifiers

Bows in the too_many_bows:bows tag can also use these special versions. They rely on Too Many Bows and UnionLib attributes.

Bow Notes

• Clumsy, Stiff, and Stretched can appear in the Too Many Bows special pool as well as the general bow pools.
• A Too Many Bows item that also matches the Forge bow tags may qualify for more than one bow pool.
• Accuracy, arrow velocity, draw speed, and arrow damage are custom UnionLib or Too Many Bows attributes; the tooltip value is the safest comparison between two bows.

Tool Modifiers

These can roll on pickaxes, shovels, hoes, and other items matched by the configured tool tags. Axes and some weapons can match overlapping tool and weapon pools.

Tool Notes

• Legendary — Ultimine adds 6 to the FTB Ultimine maximum-block limit while held.
• Extended adds 1 block of block reach and 2 to the FTB Ultimine maximum-block limit while held.
• The gathering_tools/swift_1 file is defined but not included in any pool, so it cannot roll normally.
• The two Legendary tool files are very different: one focuses on Ultimine and XP, while the alternate acts more like a combat/defense tool.

Shield Modifiers

Shield effects are configured for the off hand.

Shield Notes

• Unchained removes 2 armor points but increases total attack damage by 25% while the shield is in the off hand.
• Heavy is percentage-based knockback resistance and may show little or no benefit when the player has no existing knockback resistance.

Staff Modifiers

Staff modifiers rely mainly on Iron's Spells 'n Spellbooks. Wildsong additionally uses FamiliarsLib. Their bonuses work in either the main hand or off hand.

Staff Notes

• Spiritual is the strongest general mana-and-power roll.
• Mystical improves mana regeneration, spell power, casting speed, and cooldowns together.
• Wildsong is specifically designed for sound and nature magic.
• Bent is a trade-off: less mana regeneration but more spell power.
• Useless reduces mana regeneration and spell power but improves cast-time reduction.
• A no-bonus staffs/common file exists, but the staff pool does not currently reference it.

Fishing-Rod Modifiers

Fishing Notes

• These modifiers now use the flat additional_attributes:fishing_luck and additional_attributes:fishing_lure attributes rather than percentage-based generic Luck.
• Lucky II is configured with 2.5 Fishing Lure. Because fishing Luck and Lure behave like level-style values, the tooltip may display a rounded whole number instead of the decimal.
• Legendary is the strongest fishing roll and uses separate modifier IDs for Fishing Luck, Fishing Lure, and experience gained.
• The pool explicitly lists the four Aquaculture rods and now includes the correct forge:fishing_rods tag verifier, allowing other properly tagged modded rods to qualify.
• A redundant id: forge:fishing_rods verifier is still present, but the valid tag entry directly below it handles tag-based matching.
• The vanilla fishing rod can also match the standard tool pool through its explicit item entry.

Elytra Modifiers

The elytra pool includes the vanilla Elytra, Alex's Mobs Tarantula Hawk Elytra, and Enigmatic Legacy's Enigmatic Elytra.

Elytra Notes

• The pool weights are 50 Common, 8 Epic, and 3 Legendary, making the Common penalty much more frequent than the two upgrades within this pool.
• The Epic and Legendary Elytra files do not define a reforge hammer, experience cost, or hammer-durability cost.
• The Common Elytra modifier reduces durability by 30% and removes 1 heart.
• The Epic version adds durability and 1 heart.
• The Legendary version adds 1 heart and 10% movement speed.

Item-Specific Weapon Modifier

Mod Compatibility

Some modifiers reference attributes supplied by other mods. The basic modifier can only provide a bonus when the corresponding attribute exists.

Why an Item May Not Receive a Modifier

An item only qualifies when its item ID or one of its tags matches a pool verifier. A modded item may look like a sword, staff, shield, or armor piece but still receive no modifier when its developer did not add it to the expected Forge or mod-specific tag.

Common reasons include:

• The item is missing the required Forge tag.
• The datapack lists a tag as an item ID by mistake.
• The item belongs to a mod that uses its own unusual equipment system.
• The modifier references an attribute supplied by a mod that is not installed.
• The tier file exists but is not referenced by a pool.
• The pool references a tier file that is missing.
