YesYesYes

0 - 254

creaturesize.2daFile is hardcoded (engine values in ruleset.2da) and only used by the toolset for the names of sizesNoNoYesHardcodedNoted in description this is basically hardcoded and is for toolset only use.
creaturespeed.2daFile defining the speed of PCs and NPCsYesYesYesUnknownNeeds testing. This file can be extended but some lines are hardcoded. See creaturespeed.2da

cursors.2daNot a complete list of cursors, but used for trigger objects to define some mouse over cursors. Most cursors in the game are hardcoded and for the scripting OnPlayerTarget event you can set your own unrelated to this 2da.YesNoYesLikely 255Needs testing. GFF field is stored as BYTE (0 - 255)
damagehitvisual.2daDamage VFX line sent to the client when a particular damage is inflicted by a weapon.NoYesNoHardcodedThe amount of damage types is hardcoded.

defaultacsounds.2daThe sounds of each armor when hit, thus leather armour when hit by a sword has the impact effect sound like leather. Only is loaded if the ArmorType column of appearancesndset.2da is blank, and it looks up the chest AC value.YesNoNoUnknownNeeds testing. New AC values can be added but only incrementally (so higher AC, eg: 8, 9, 10 could be added next).
des_xxx.2daThese 2da files were used by Bioware designers to have custom systems that work with Get2DAString() in scripts, eg for crafting.NoYesNoN/ANo limits as such apart from what limits 2DA files have naturally
diffsettings.2daDifficulty Settings used by the game, at least the ones Bioware made editable.YesYesNoHardcodedThe amount of difficulty options and what options are editable is hardcoded.

doortypes.2daList of doors tied to various tilesets. Clients will load it for most likely the sound reference.YesYesYesUnknownNeeds testing.
effecticons.2daEffect icons used by the game, now extendable massively in EE with EffectIcon.YesYesNo

1 - 255

This 1 - 255 limit was confirmed in EE for EffectIcon. Previously all effect icons were hardcoded but the network traffic to send them limits the number. Line 0 is invalid.

epicattacks.2daAttack progression for epic levels (21+). Clients and toolset is just for showing numbers.YesYesYes60Classes are limited to 40 levels for PCs and 60 levels (mostly) for NPCs. Note the epic levels are 21+ so first 20 lines would be ignored usually.
epicsaves.2daSave progression for epic levels (21+). Clients and toolset is just for showing numbers.YesYesYes60Classes are limited to 40 levels for PCs and 60 levels (mostly) for NPCs. Note the epic levels are 21+ so first 20 lines would be ignored usually.
excitedduration.2da"Excited" duration, ie; combat music time! Both options are the same, clients say it loads but is it used for anything? Probably not. It is also probably not worth altering this since...who knows what might happen in the engine. If you know maybe post it here!Yes but not used?YesNoHardcodedThe entries here are hardcoded.
exptable.2daUsed to figure out when the characters levelup.NoYesNo41Line 41 is actually making level 40 the highest. EE has some bugs if you go over 40 levels for PCs around spellcasting.
feat.2daFeats available for creatures to take, or are granted to them.YesYesYes

0 - 32768

uint16 used in network however not recommended to go over 32K even if 65,536 is absolute maximum. There are likely problems with subdial feats if you do this due to how they are identified.

footstepsounds.2daSound files loaded for particular footsteps depending on appearance.YesNoNoUnknownNeeds testing.
fractionalcr.2daSorts fractional CR for purposes of encounter challenge rating (working out what monsters to spawn).NoYesNoHardcodedThe amount of lines are hardcoded, although perhaps you can alter bits of it, it may break something.
gender.2daEssentially a list of genders for the toolset, and on clients which TLK string to load for them. Server just uses a coded list (ie like the GENDER_* constants in nwscript) although it might use it via. Get2DAString if needed.YesNoYesHardcodedEven if you can add more genders you'd need NWNX to have the server end work with them properly.
genericdoors.2daThe generic "general" doors and their modes/info.NoYesYesUnknownNeeds testing.
hen_companion.2daAnimal Companions list. Used for clients to show at levelup, and servers to load the right resref. Toolset doesn't load it since NPCs have these settings wiped.YesYesNoUnknownNeeds testing.
hen_familiar.2daFamiliar list. Used for clients to show at levelup, and servers to load the right resref. Toolset doesn't load it since NPCs have these settings wiped.YesYesNoUnknownNeeds testing.
inventorysnds.2daThe sounds when inventory items are moved around the inventory or picked up (column "InvSoundType" in baseitems.2da). Server just sends the column ID number to the client to find the file to play.YesNoNoUnknownNeeds testing.
iprp_abilities.2da

Item Property - ability list.

For each IPRP file it's assumed server needs it for item property generation/properties or Get2DAString for crafting. The client will need it for item examining so the right property info is loaded.

YesYesYesHardcodedNumber of abilities are hardcoded in the engine.
iprp_acmodtype.2daItem Property - AC modification type.YesYesYesHardcoded5 hardcoded AC types.
iprp_addcost.2daItem Property Cost Table - "Additional"YesYesYesUnknownAdditional Cost table things like Cursed identifiers can be added here.
iprp_additional.2daItem Property - "Additional"YesYesYesUnknownAdditional Cost table things like Cursed identifiers can be added here.
iprp_aligngrp.2daItem Property Alignment GroupsYesYesYesHardcodedAmount of alignments is hardcoded.
iprp_alignment.2daItem Property AlignmentsYesYesYesHardcodedAmount of alignments is hardcoded.
iprp_ammocost.2daUnlimited Ammo options. Resref of the "unlimited ammo" to equip depending on if arrow, bolt or bullet.YesYesYesUnknownLooks like more could be added.
iprp_ammotype.2daUnlimited Ammo "Ammunition type". Since it's tied to the weapon this is probably only used by the toolset, since the iprp_ammocost.2da determines the TLK string of the actual type (Eg; "Unlimited Fire 1d6")YesYesYesHardcodedAs with ranged weapons, ammo is hardcoded to 3 types.
iprp_amount.2daItme Property "Amount". Is simply 1, 2, 3, 4, 5 with TLK strings "Amount: 1", etc. attached. It used for things like Monster On Hit: Ability Drain [Drains Strength] [Amount: 3]YesYesYesUnknownNeeds testing.
iprp_arcspell.2daItem Property Arcane Spell Failure amounts.YesYesYesUnknownNeeds testing.
iprp_base1.2daThis is an intentionally blank cost table file referenced as line 0 in iprp_costtable.2da. It is used for any property which has no cost table value for it. How does it work out the cost? well the subtype 2da tends to have a Cost column. Very confusing I know.YesYesYesLeave aloneLeave it alone blank, it might break things if edited since it's note expected to have anything in it.
iprp_bonuscost.2daItem Property Bonus Cost. Used for ability score increases.YesYesYesUnknownNeeds testing. However ability scores may overflow/cap if going too high.
iprp_chargecost.2daItem Property Charges / Use or Uses / Day options.YesYesYesHardcodedThe amount of these is hardcoded since there is no options in this 2da for what each one is defined as. So no 10 Charges / Use can be added.
iprp_color.2daItem Property Light Color choice.YesYesYesHardcodedThe lights relate to particular VFX lines, thus this list is hardcoded (but changing the TLK values and assinging different VFX models/progfx info may work).
iprp_combatdam.2daItem Property Extra Melee Damage type of damageYesYesYesHardcodedOnly can have the 3 main physical damage types for this item property.
iprp_costtable.2da

Cost Table. This defines what 2da is loaded for each CostTableResRef ID number in itempropdef.2da

You can add new item properties (which are just for the item description or to add/remove cost, and have scripted effects) by adding more rows to this.

YesYesYesUnknownAdditional rows can be added just needs testing.
iprp_damagecost.2daItem Property Damage Bonus and EffectDamageShield / some other things that need static and variable bonuses like 1d6 and 2d8.YesYesYes127 (or possibly 128)

Certainly going to line 129 or higher works for the server end (damage is done correctly) but the client won't show it correctly in the character sheet because it looks up 2da line as a negative (impossible). Line 159 was tested which had the string "-97 Magical Damage" since 159 - 128 = 31, and 128 - 31 = 97.

It shows correctly on items, and higher lines are safe for NPCs to use.

iprp_damagetype.2daItem Property Damage Bonus type of damage to apply. Interestingly has "subdual" and "physical" as options, perhaps hinting at an earlier damage system more aligned to D&D rules.YesYesYesHardcodedDamage types are hardcoded in the engine, although the names can be at least altered here.
iprp_damvulcost.2daItem Property Damage Vulnerability cost table, eg 50% fire vulnerability.YesYesYesUnknownAdditional rows can be added just needs testing.
iprp_feats.2daItem Property Bonus Feat list. Keeps the amount in the toolset managable but you can extend this to be almost any feat.2da entry (some however will not function).YesYesYesUnknownNeeds testing. Likely at least the length of feat.2da
iprp_immuncost.2daItem Property Damage Immunity cost tableYesYesYesUnknownAdditional rows can be added just needs testing.
iprp_immunity.2daItem Property Immunity: Misc table, eg: Immunity: Death MagicYesYesYesHardcodedThis seems a static hardcoded list, engine defined, which has no correlation to the script constants, sadly much smaller too.
iprp_kitcost.2daItem Property Healing Kit cost tableYesYesYesUnknownAdditional rows can be added just needs testing.
iprp_lightcost.2daItem Property Light cost table (Brightness)YesYesYesHardcodedSpecific visualeffects.2da lines are loaded with a combination of this and iprp_color.2da. Sadly these are hardcoded although the VFX lines could be altered.
iprp_matcost.2daItem Property Material cost tableYesYesYesUnknownAdditional rows can be added just needs testing. This property doesn't do anything in the engine and can be altered fine.
iprp_material.2daItem Property Material tableYesYesYesUnknownAdditional rows can be added just needs testing. This property doesn't do anything in the engine and can be altered fine.
iprp_meleecost.2daItem Property cost table for a variety of basic +1, +2 etc properties - AC, Attack, Enchantment, Regeneration, etc.YesYesYesUnknownAdditional rows can be added just needs testing.
iprp_monstcost.2daItem Property Monster Damage cost table.YesYesYesUnknownAdditional rows can be added just needs testing.
iprp_monsterhit.2daItem Property Monster: On Hit table. It is hardcoded so should probably not be altered.YesYesYesHardcodedThese references are hardcoded, even if the 2da is used to load the correct parameter tables.
iprp_neg10cost.2daUsed for Item Properties; Ability Score Reduction and Skill Penalty.YesYesYesUnknownAdditional rows can be added just needs testing.
iprp_neg5cost.2da

Used for Item Properties; Enchantment Penalty (attack and damage), Damage Penalty, Decreased AC, Reduced Saving Throws, Attack Penalty

YesYesYesUnknownAdditional rows can be added just needs testing.
iprp_onhit.2daItem Property On Hit table, defines all the hardcoded engine On Hit properties and the param1 values (eg; what ability to drain, the duration/change to occur, etc.). The cost table determines the DC.YesYesYesHardcodedThis list is hardcoded to engine values. However the sub properties (DC, chance/duration) can be altered for particular ones as noted.
iprp_onhitcost.2daItem Property On Hit cost table (the DC of the On Hit saving throw)YesYesYesUnknownAdditional rows can be added just needs testing.
iprp_onhitdur.2daItem Property On Hit duration table. Used only for some On Hit properties, it defines things like 5% chance / Duration 5 rounds.YesYesYesUnknownAdditional rows can be added just needs testing.
iprp_onhitspell.2daItem Property On Hit Cast Spell table. Add more spells to use in this property here.YesYesYesUnknownAdditional rows can be added just needs testing.
iprp_paramtable.2daItem Property Parameter Table table. In itempropdef.2da the column Param1ResRef refers to this table.YesYesYesUnknownAdditional rows can be added just needs testing.
iprp_poison.2daItem Property On Hit: Posion. It simply lists the poison ability damage. Otherwise hardcoded.YesYesYesHardcodedThe 6 ability scores are all you're going to get.
iprp_protection.2daItem Property Damage Reduction, amount of enchantment needed to penetrate it (eg; +2 would need a +2 weapon to bypass).YesYesYesUnknownThis is likely hardcoded due to other aspects of the game assuming a +0 to +20 range for DR and enchanted weapon properties. However it might be extendable, but would need a lot of testing.
iprp_qualcost.2daItem Property Quality cost tableYesYesYesUnknownNeeds testing but this is essentially a customisable item property which has no ties to the engine so could be extended fine.
iprp_quality.2daItem Property Quality tableYesYesYesUnknownAs above.
iprp_redcost.2daItem Property Reduced Weight cost table (eg: -20%, -40%)YesYesYesUnknownNeeds testing. Likely can be extended however; has a suitable Value column to use.
iprp_resistcost.2daItem Property Damage Resistance cost table (Eg: 20/-, 30/-)YesYesYesUnknownNeeds testing. Likely can be extended however; has a suitable Value column to use.
iprp_saveelement.2daItem Property: Improved/Decreased Saving Throws. Note there are the entries for Traps, Spells, Law, Chaos, Good and Evil but without valid TLK entries which means they cannot be selected. Adding TLK entries to them allows them to be picked.YesYesYesHardcodedThe list is hardcoded, especially since it includes things that are not usual saving throw types (dummied out) like Backstab and Illusion.
iprp_savingthrow.2daItem Property: Improve Saving Throw Specific and Reduce Saving Throw Specific.YesYesYesHardcodedHardcoded; has "All" plus the 3 base throws Fortitude, Will and Reflex.
iprp_skillcost.2daItem Property: Skill Bonus cost tableYesYesYesUnknownMore values can likely be added needs testing to what extent and what value breaks skills in general (if you remove the cap on bonuses).
iprp_soakcost.2daItem Property: Damage Reduction, the soak value cost table (eg; the 30 in Damage Reduction +15 / Soak 30)YesYesYesUnknownNeeds testing. Likely can be extended.
iprp_spellcost.2daImmunity: Specific Spell. Yes you have to add your new spells to this list to have specific immunities on item properties.YesYesYesUnknownNeeds testing. Likely quite large.
iprp_spellcstr.2da

On Hit: Cast Spell caster level of the spell cast, eg: On Hit: Call Lightning [Level 10]

Really wish this method was used for the Cast Spell property for variable spell levels there! Alas...

YesYesYes0 - 40 likelyLevel 40 caster level is usually the max, might be it can go up higher needs testing.

iprp_visualfx.2daItem Property Visual FX - used for weapon VFX. Extendable with NWN:EEYesYesYesUnknownNeeds testing. Can be extended.
iprp_walk.2daItem Property Special Walk. In EE you can now define more of these and use them properly.YesYesYesUnknownNeeds testing. Can be extended.
