Necromancer 6th Rank Quest

[Oreznoclaf]

Hi all,
I have searched the forums, but I am still unsure of how people were able to complete this quest. It requires of me to kill a halfling swishbuckler, but I am having a lot of trouble finding him. I have killed Red Eye Jack and the named barb several times, but to no avail spawning him. Are there any other mobs that I need to kill to make him spawn? Thank you in advance
