Modifiers

A Modifier applies permanent changes to an item's statistics. All Weapons and Accessories have a 75% chance (3 in 4) of receiving a random Modifier when crafted using left click (except on the Mobile Version (0% chance), purchased from an NPC, looted from Chests/Crates, or collected from drops. Modifiers can also be added or changed via the Goblin Tinkerer's Reforge function.

A Modifier changes the name of an item by adding a prefix, such as "Adept", "Godly", or "Broken" (eg. "Demonic Minishark"). A complete list of all 112 of these appears below. Hovering the cursor over an item with a Modifier in an Inventory slot will show the modification details beneath the item's description.


 * Accessory modifiers will grant a bonus to one of the player's stats, such as defense, movement speed, or maximum Mana. It is applied as long as the accessory is equipped.
 * Weapon modifiers alter the statistics of that particular weapon, and may be positive or negative, with up to 5 positive or 3 negative effects at once. Tools that act as Weapons, such as Pickaxes and Hammers, may also have these Modifiers.

Reforging
Reforging is a service provided by the Goblin Tinkerer to switch an item's Modifier, or add a Modifier to an unmodified item. Reforging will apply a new, random Modifier to an item, replacing any existing Modifier. Crafting a new identical item can have the same effect, though crafting has a chance of resulting in an item with no Modifier, whereas Reforging will always apply a Modifier. Crafting may also require materials not in the player's possession, whereas Reforging only requires Coins.

The Goblin Tinkerer charges one third of the item's current buy value, which is approximately 1.67x its sell price, or 1/3 of its base value. Existing modifiers affect this value, so items with poor existing modifiers are cheaper to reforge, while reforging an already well-modified item will be more expensive. The Discount Card can be used to lower reforge costs by 20%.

Reforging can be done by talking to the Goblin Tinkerer, choosing Reforge from the options, and then placing the item you wish to reforge in the box that appears below your inventory. Below the listed cost is a small black hammer that, when clicked, allows you to reforge the item for the listed price.

Accessory Modifiers
Accessory modifiers are active when equipped. Every accessory item can be reforged with the exception of the Guide Voodoo Doll, Clothier Voodoo Doll, and all the Music Boxes. Accessories can have one of the following nineteen modifiers attached to them:

Weapon Modifiers
These modifiers only apply when the weapon is being used. Weapons that have no Knockback cannot be reforged with modifiers that change Knockback, such as Drills, Magical Harp and many other guns (such as the minishark).

The Light Disc and Bananarang cannot have modifiers.

Universal
Flails, Spears, Boomerangs (except for the Light Disc and Bananarang), Chainsaws, Drills and Jackhammers (including the Drax) can only have universal prefixes, because they can't have their speed modified.

Universal modifiers can also be found on all other weapon types. The best universal prefix is Godly.

The best prefix for a Drill is Demonic (as they have no knockback), except for the Drax, whose best prefix is Godly (since it has knockback).

There are 14 Universal modifiers.

Displayed values may differ due to rounding.

Common
All weapons that are melee, ranged, or magical can have these mods.

There are 10 common modifiers.

Displayed values may differ due to rounding.

Melee
All Pickaxes, Hammers, Axes, Hamaxes and swing Melee Weapons can be reforged with these mods, in addition to the top two categories. (Due to their low base damage, the Wooden Hammer and Copper Axe cannot be affected by modifiers that change their damage by 15% or less.) The best melee prefix is Legendary. Note that since the patch 1.1.1 it's no longer possible for a Spear to have any prefix that increases size. This includes Legendary, so the best prefix possible for a spear is Godly.

There are 16 Melee modifiers.

Displayed values may differ due to rounding.

Ranged
All Bows and Guns (Excluding the Space Gun and Laser Rifle which count as magic Weapons) can be reforged with one of the following mods, in addition to the top two categories. The best ranged prefix is Unreal. However, the Minishark, Star Cannon, Flintlock Pistol, The Undertaker, and the Clockwork Assault Rifle, and all bows of standard ore and wood (Wooden Bow through Platinum Bow) while also in this category, are unable to receive any modifiers that affect knockback, as they have none. The best prefix for a ranged weapon without knockback is Demonic. The Harpoon which is also classified as a ranged weapon, cannot receive the Unreal modifier but it can get Godly.

There are 12 Ranged modifiers.

Displayed values may differ due to rounding.

Magic
All Magic Weapons (mana consuming) can be reforged with one of the following mods, in addition to the top two categories. The Magical Harp and Nimbus Rod both lack a Knockback value and are unable to receive modifiers that affect Knockback, the best choice for these are Mystic or Demonic. Magic weapons must use at least 4 mana upon use to receive any modifier that decreases mana usage. The best magic prefix is Mythical.

There are 12 Magic modifiers.

Displayed values may differ due to rounding.

Complete List
Only swung Melee weapons can have their Size modified. Only Ranged weapons can have their Velocity modified. Only Magic weapons can have their Mana Cost modified. Certain weapons can't have their Speed or Knockback modified.

Displayed values may differ due to rounding.

Weapons
Due to various limitations with certain Weapon classes, determining the best-possible Modifiers may not be as simple as comparing statistics, and players can waste money trying to acquire Modifiers that are impossible to achieve for their given Weapon. Here is an easy rundown of the best possible Modifiers for each weapon, or weapon type:


 * As Minions cannot deal critical hits, their knockback is negligible even with modifiers, and speed and mana cost only affect their initial summoning rather than the minion attacks themselves, the Ruthless Modifier offers the most effective Minion boost by solely increasing the Minion's damage per hit the most.
