Bioware didn't bother to update the list of pre-defined constants in nwscript when they expanded the .2da files for epic levels in HotU. So, here is a quick run-down on how to use the 2da files to access the missing constants.
First, you must get access to the 2da files. While you can use
NWN Explorer and dig around in NWN\data\xp2patch.bif under "Game Data" it's much easier to just download the current full 2da source files from this link (at the bottom):
Neverwinter Nights Miscellaneous Files.
Now to address this problem:
what i would like to know is, is it possible for standard nwnscript to handle adding up to 20 damage to an item? They dont seem to have the constants for a damage type of 20. While it also seems maxed at 10.
Open up iprp_damagecost.2da:

You only need to look at the first column which is the actual numeric value of the constant and the corresponding damage amount under the "Label" column.
For example the following three lines are the same code:
//Using pre-defined constants
ItemPropertyDamageBonus(IP_CONST_DAMAGETYPE_ACID, IP_CONST_DAMAGEBONUS_1d6);
//Using value from iprp_damagecost.2da
ItemPropertyDamageBonus(IP_CONST_DAMAGETYPE_ACID, 7);
//Using value from iprp_damagetype.2da and iprp_damagecost.2da
ItemPropertyDamageBonus(6, 7);
So, to make the damage 20 you'd replace the 7 in the above example with 30.
