This article covers the layout of the file; for the default contents, see spells.2da (contents).

The spells.2da file is the .2da that defines which spells are available in the game. It specifies any restrictions the spell has, any scripts that are fired on use, and any other information governing the use of the spell.

Columns of spells.2da
Name Description
ID (no actual name) Row numbers for the benefit of human readers. The game engine ignores the value in this field, instead generating sequential row numbers as the file is read. It is good practice to keep the entries in this field sequentially numbered to avoid confusion.
Label A text value identifying the spell associated with this row. It is not used by the game engine, but makes it easier to locate specific spells within the file. All spaces should be replaced with underscores ( _ ).
Name A StringRef indicating a string that will be displayed in the game as the name of the spell.
IconResRef A text value (ResRef) specifying the filename of the icon displayed in game for this spell. By convention, all icon names start is_, for icon spell, followed by the spell name, abbreviated if necessary. The maximum length for the text/filename is 16 characters.
School A letter value specifying the spell school for the spell. A = Abjuration, C = Conjuration, D = Divination, E = Enchantment, N = Necromancy, T = Transmutation, V = Evocation

Column notes Edit

Both the MetaMagic field and TargetType fields are bit fields. The below tables show the hexadecimal values that are added together to get the values for use in the .2da file. For an online calculator for these columns, see the external links at the end of this article.

MetaMagic values
ValueMetamagic
0x01empower spell
0x02extend spell
0x04maximize spell
0x08quicken spell
0x10silent spell
0x20still spell
 
TargetType values
ValueTarget
0x01self
0x02creature
0x04area/ground
0x08items
0x10doors
0x20placeables
0x40triggers

A value of 0x40 can be used as a target type for triggers, encompassing both trap triggers that have been discovered and area transition triggers, but this does not work very well.

Hordes of the Underdark specific change:
All player-castable spells need to have bit 0x08 (target items) set in the target type to allow them to work with the crafting system (for brew potion, craft wand, and scribe scroll). The responsibility for blocking spells from targeting items other than a blank potion, wand, or scroll has been shifted to the crafting routines. To indicate whether or not a spell is allowed to target items outside the crafting system, the "CastOnItems" column in des_crft_spells.2da needs to be used.

General notes Edit

  • It appears there is a limit of 255 to the number of spells which can be put into class spell book. Attempting to log in with a character with more spells than this will crash the server (or crash the game in single player). This limit applies only to the actual spells known by a character, not the spells available on level up. Since radial spells — such as protection from good and protection from evil — count as one spell in the spell book — protection from alignment, for this example — adding spells as radial options is one way around this limitation.
  • BioWare followed a naming convention for their spell scripts, as detailed in the following table.
Character positionsValue(s)Description
1 & 2nw, x0, x1, x2The first two letters designate which game/expansion the script came from: nw for NWN, x0 or x1 for Shadows of Undrentide, and x2 for Hordes of the Underdark. For custom scripts, many authors will use their initials here.
3 _ Underscore
4 & 5s0, s1, s2, s3s0 is used for player castable spells, s1 for monster spell-like abilities, s2 for special ablities/feats, and s3 for items/item properties.
6 _ Underscore
7-16<spell name>The remainder of the script name is the spell name, abbreviated if necessary to fit within the 16 character limit.
