Ah,it seems that only those 6 were created then...
I just unearthed the thread where we'd design those.It's kind of hard to believe it's been 5 years already.
http://www.hellgateaus.cyou/forum/talk/design-your-own-unique-item/Edit: Speaking of which,and since we're mentioning custom items alongside "options"...Let me go slightly off the rails here.If anything,I may give you a horrendous idea or two along the way.
Some friends and I used to discuss this topic at length,back in the day.Nadja was an Engi nut,our friend Necrovatis was a Guard nut so it kind of worked out as a coffee break distraction.Reanimator was all-new territory,and we'd all squabble in it from time to time in spite of it all being alien to us.
The ideas that came on the table varied from switching around the elements of the Evoker skills (spectral Hellfire and so on) to swords that would create fields per swing.Necro's sadistic impulse to provide Guardians with Warpers and Reapers was usually the discussion-ender,so to speak.
Where I'm going with this is,simply,that modders still look like Reanimator-wielding wizards to me to this day.Many of our wildest desires and far-fetched theorizings may have never been realized,but just being able to see Nagahaku released along with your perfect follow-up is satisfactory beyond words.Between Nagahaku,Lost London and Revival,seeing such attempts to pump life into this game even today is truly a sight to see
