Caltrops resemble large metal jacks with sharpened points rather than balls on the ends of their arms. They can be thrown to cover a small area of effect. For every round that a person is standing on the field of caltrops they take 1 point of damage. One pouch of caltrops can do a total of 25 points of damage.

The ERF contains:
. Three caltrops scripts
. Two caltrops blueprints (under 'Items - Weapons - Throwing')
. One placeable blueprint (under 'Placeables - Misc Props')
The HAK contains:
. A caltrops visual effect
. A copy of SPELLS.2DA (Storm of Zehir 1.22)
Copy the HAK file to your 'Documents\Neverwinter Nights 2\hak' folder.
The test module goes into 'Documents\Neverwinter Nights 2\modules'
To use caltrops in your own module, associate the 'Caltrops.hak' file with it and import the scripts and placeables from 'Caltrops.erf'.
Line 471 of SPELLS.2DA contains the caltrops entry, should you want to merge it with your own version of the 2DA. The only changes made are to TargetType (now '0x2E'), ProjType (now 'ballistic'), and REMOVED (now 0).
There are two types of caltrops; normal and poison. The blueprint for the poisoned variety has a local 'POISON' integer variable set to '1'.
Caltrops will only damage enemies, however all creatures standing on them must make a reflex saving throw (DC 14) to avoid being slowed (even the PC and party members). Once thrown, they will remain until they've dealt out 25 points of damage, or until a suitable area-of-effect spell is cast on them (gust of wind, acid flask, acid fog, vitriolic blast, or vitriolic sphere).
