How do you create a faction hit?

[eski2]

For example, Critters of JaggedPine is on factionlist, id 61. In the npc_types table, id 181038 is a_Darkpaw_warrior. I can see it's npc_faction_id is 857 .

Looking at table npc_faction_entries npc_faction_id 857, i can see (god i wish i could copy paste a few relevant rows from heidiSQL instead of the whole table)

faction_id value npc_value
73 -30 1
159 10 0

So i assume this means every kill equals 30 points off faction_list id 73 (Darkpaws of Jaggedpine) but i don't know what npc_value is.
159 is Jaggedpine Treefolk so that's slowly going up by 10. I presume if i add a row
857 61 30 0

then killing a gnoll of that type will make the critters of jaggedpaw less homicidal to me. Does this make sense or am i making a mistake?
