How to get syndicate members' signature veiled mods?

For example Elreon's "Channelling Skills have -3 to Total Mana Cost".

Tried to google it but got no answer. No info on wiki either.

And I'm on SSF, can't buy items with signature veiled mods.

First, you must have Elreon in your current Syndicate members. If you keep interrogating him eventually someone will remove him or he will ask to be removed, so it's better to level him (bargaining or just releasing) and keep him in your board, doesn't matter which safehouse.

Elreon crafts are very rare. I had some leagues I could not max it. So it might take a lot of Syndicate grind to get what you want.

Good luck and stay sane exile!

They randomly drop from those specific members. Some have minimum lvl requirement to drop which you can check here. For example minimum lvl requirement for Elreon's jewelry is 60

Also once you get the mod that you want on an item you can then veil the item again using Aisling in research and it will have the same options to unveil so you can get more progress of the craft. Since she adds veiled prefix/suffix at random make sure the item has the free slot for exactly what you need

So I just keep killing (or jailing) Elreon and eventually he drops items with his signature mods, right? Just as with normal, non-signature veiled mods?

There are no additional requirements?
