rank 4 (64–75)% increased Spell Damage Gain 12% of Non-Chaos Damage as extra Chaos Damage

How do I learn rank 4 (64–75)% increased Spell Damage
Gain 12% of Non-Chaos Damage as extra Chaos Damage.

I have run like 200 red maps and killed betrayal guys with no drop that gives this enchant. Killed 10 safehouses etc.

Can't really get this. Pure RNG?

I'm p. sure modifiers come from specific members, so you want to find out who gives that one and push them into a good position.

did you ever find it?

Nope, still not yet. Got all except that one ^^

According to my experience and to wiki you need to move Aisling* to Research division (make him rank 3 and leader of the division if possible - leaders have rewards doubled).

*Crafting Bench that adds a veiled mod to a Rare item, with a chance to add a second veiled mod at higher ranks
(NOTE: Veiled mod outcomes are fixed on a per-item basis)

Once you have done it (and before raiding the house) prepare any two handed ilvl 75 melee weapon and bcos (64–75)% increased Spell Damage - Gain 12% of Non-Chaos Damage as extra Chaos Damage mod is prefix all suffix mods should be blocked (He can´t offer you suffix modifiers and I would aim for two open prefix modifiers if possible bcos there´s a chance you can add more Veiled mods on an item - with higher rank member).

That´s how I got +1 totem shield (at first try but maybe I was lucky … there are more mods you might get).
