Icons are textures used for many of the in-game GUI items.
Sizes and Format
They generally are TGA format to increase clarity - although DDS can of course be used (which may be recommended if doing high resolution icons that are scaled up and down with GUI scaling NWN:EE has).
They can be increased in size past the default sizes Bioware originally intended but this comes at the cost of them not loading in the toolset properly. To work around this you could work on a toolset version of hakpack files or override content with original sized icons, and switch to higher resolution ones for distributing to players.
Icons of course have transparency - especially in the inventory - which is where there is an absence of pixels in the TGA/DDS file.
The main thing if changing the size is the ratio should stay the same else stretching would presumably occur - or possibly the texture won't load - so doubling the size is easiest for a HD upgrade, or 4x is also possible if you do AI upscaling.

Hardcoded Icons
See Hardcoded Icons for a basic list, these are loaded by name by the engine, not from a 2da file.
Non Hardcoded Icons
These are referenced by 2da directly or indirectly. Many of these are pretty much only there for the TLK reference and icon.
| 2da file | Bioware Default Prefixes | Icon Type |
|---|---|---|
| actions.2da | ir_ ife_ (feat) isk_ (skill) | A subset of actions - not all of them are here naturally, but most are. The icons appear in the radials, and top left "action queue" as appropriate. Some feat and skill icons are also referenced in actions.2da |
| classes.2da | ir_ | Class icons are shown generally in levelup screens only. Note creature classes just default to ir_wizard (or ir_cleric for oozes) because it doesn't really matter (note for Ooze, most of the cleric line was copied) |
| baseitems.2da | w (weapon) iw (default weapon icon) it_ (item) iit_ (default item icon) cloak (cloaks) a (armor) | Shown in all sorts of places. The "Defaault" ones shouldn't usually show up. |
| domains.2da | id_ | Domain icons as show in the level up and character sheet. |
| effecticons.2da | ief_ | Effect Icons such as "ief_damresist" for damage resistance, on the character sheet, examine panel and top right of the players screen for effects on self. Helpful tip; different immunities, or damage type immunities can be specified exactly here (eg; Immunity to Critical Hits can have a different icon from all the other immunities) |
| feat.2da | ife_ | Feat icons as show in the level up and character sheet. |
| racialtypes.2da | **** (none) | BeamDog added support for specifying an icon for each race with the new Icon column. By default, no icon is specified. |
| skills.2da | isk_ | Skill icons as shown in the level up and character sheets. Some skill icons are also used in radial menus when performing actions. |
| spells.2da | is_ (usual spells) ir_ (several generic monster abilities/activate item) | Spell icons, used in levelup, spell books, action radials, spells cast from non-scrolls etc. |
| iprp_spells.2da | iss_ | Scroll icons - the icon that replaces the blank scroll directly (ie it has the scroll background etc.). If the spell is being cast from another item type it'll go into a radial and look for the usual spell icon (see spells.2da) |
