Grenade Parts Guide

Grenades are made up of up to 10 different parts. Unfortunately only 5 of these slots use parts with models, and even within these it isn’t possible to tell between every non unique part visually.

Blast Radius Parts

There are 4 non-unique blast radius parts.

Child Count Parts

There are 7 non-unique child count parts.

These child count bonuses only apply if the payload actually supports child grenades, otherwise they have no effect.

Deliveries

There are 7 non-unique deliveries. The delivery changes how your grenade is thrown.

Materials

There are 28 non-unique materials, one for each rarity-manufacturer combination. The manufacturer changes the model, while rarity changes the skin applied to it.

Only Torgue materials provide a bonus, of which all rarities are identical.

Triggers

There are 6 non-unique triggers.

Accessories

The accessories define both the element of the grenade and it’s (unlisted) status chance modifier.

There are 26 non-unique accessories - each element has 5 parts at different grades, and there’s a single part for explosive.

Damage Parts

There are 8 non-unique damage parts.

Payloads

The payload controls what exactly happens when a grenade explodes. Most unique grenades use unique payloads to implement their behaviour. Payloads also determine if child grenades are supported - even with several bonuses, none will spawn if the payload is incorrect.

There are 6 standard payload types. In TPS, each of these has a duplicate which can also shatter air masks, meaning there are to a total of 12 non-unique payload parts.

Status Damage parts

There are 6 non-unique status damage parts.

Inventory Balances

The Inventory Balance defines what parts a certain item can have. Balances themselves do not affect stats, but are they very important for the actual generation of items.

Grenade Definitions

Like the name might suggest, the definition essentially defines all the unique properties of each grenade type. There is one standard definition used by all non-unique grenades, while most unique grenades use their own unique definition.

Definitions are very important if you’re trying to calculate exact stats, but otherwise can be mostly ignored.

Expand

To start with, they define the base values for all stats stored on the grenade. Unlike with weapons, this is simply done using regular pre-add bonuses, so see the full parts reference for details.

They also define all grade bonuses, and how exactly they get converted into standard bonuses. Definitions do not necessarily define all grade slots, if a slot’s undefined then no grade bonuses will be applied to it.
