This file defines the interaction comments between NPCs. The interaction comments themselves are strrefs stored in the CRE file (offset 0xa4), and are grouped into interaction types as per SOUNDOFF.IDS/SNDSLOT.IDS. The engine randomly selects which specific comment to make out of the apportioned range (e.g. INSULT_1 or INSULT_2 etc.). Some interaction types have a response, selected from the response group of the target CRE, if the relevant row/column crossing is set in this file.
First column and row are filled with NPC death variables, while the column/row intersections are marked by the letters indicating which interaction should take place in the interaction circumstance; the list of interaction types is below along with the sound range from soundoff.ids/sndslot.ids:

Row/Column intersection	Type	Response
i	Insult [44-46]; numbers indicate a specific insult slot	Response_to_insult [58-60]
c	Compliment [47-49]; numbers indicate a specific compliment slot	Response_to_compliment [55-57]
s	Special [50-52]; numbers indicate a specific special slot	None
0	No interaction	None
