Item level restriction

Item level restriction (ILR) is a Neverwinter Nights server and single-player setting which prevents characters from equipping or using items whose required level is greater than the character's level. The required level is based upon the item's value, with the exact correspondence defined in itemvalue.2da. A setting in nwnplayer.ini determines whether the game will enforce ILR — the Single Player ItemLevelRestrictions entry in the "Game Options" section is used for single-player, while the ItemLevelRestrictions entry in the "Server Options" section is used for multiplayer. The default is to have ILR turned off in single-player and on in multiplayer.

The usefulness of ILR is two-fold. First, the ostensible use is to prevent players from using items they were not intended to have access to. This is more important on persistent worlds than in other settings, as in other settings, access to items can be more tightly controlled. The second use is for builders, for whom ILR can serve as a guideline when designing items. The Toolset displays the ILR requirement for an item (in the "General" tab of an item's properties, listed as "Required Level"), so a builder can compare this to the intended level of the recipient of the item. If the ILR exceeds the intended level, then the item is too powerful according to the ILR guideline. (On the other hand, if the ILR is less than the intended level, then the item may be appropriate, just not among the few most powerful items a character might possess.) Of course, if ILR is not enabled when the game is played, then ILR is jut a guideline that builders can ignore if they choose. In addition, builders may reject BioWare's version and define their own guideline by modifying itemvalue.2da (which would not need to be distributed with the module if the intent is for the module to be played with ILR off).

Specs

The maximum item values usable at each level in the standard game are as follows. (The values for levels above 40 are only applicable to non-player characters.) In particular, items whose value exceeds 4,200,000gp cannot be used by player characters when item level restrictions are being used, and items whose value exceeds 8,200,000gp cannot be used by anyone when this setting is in effect.

As a general guideline, the required levels for melee weapons with a certain enhancement bonus (and no other properties) are listed in the following table.

Minimum level by weapon enhancement

Enhancement Required level +1 3 +2 7 +3 10 +4 13 +5 15 +6 21 +7 21 +8 22 +9 23 +10 26

Enhancement Required level +11 29 +12 31 +13 34 +14 37 +15 39 +16 41 +17 45 +18 49 +19 53 +20 58

Notes

• As mentioned above, the limit for each level can be changed by modifying itemvalue.2da. One particular modification that removes the limit for level 40 PCs (allowing them to use any item that can be created in the Toolset, altering the balance guidelines of ILR) is available from the Vault.^[1]
