|Type||4 (dword)||The basic spell type
|SpellCost||4 (dword)||Spell cost if autocalc is off|

|Flags||4 (dword)||Spell flags
 Effect Subrecords
There will be one set of EFID/EFIT subrecords for each regular effect applied to the ingredient and a set of EFID/EFIT/SCIT/FULL subrecords for each script effect. The data appears to be identical to that used in the ENCH record.
Note that the SPEL record can have multiple FULL subrecords. The first is required and will be the item name. Any subsequent FULL subrecords will be a script effect name.
