VS demons

where do these vs mods usually drop, i realized sometimes i get 19% vs demon mods in HM in chos estate (yes i farm it) but where do they usually drop more?

Afaik there isn't really anything that influences what mods drop. I don't think monster type affects it (as you've shown) so unless someone shows proof I think it's just luck.

Well, most of the time, and I've got several, for Axe, Bow, Sword and Staff
where comming from Dragon Moss

I only got them in Factions but that could just be lucky/unlucky. Got them in starter Island aswell as mainland(kurzick area).

i got a few of them from farming guardian moss outside boreas seabed

When vanquishing the lux kurz areas of cantha i got loads of em, about 4 or 5 demon ones, and other randoms like dragon and ogre.

Do you mean % Armor vs Demons or are you talking about the weapons mods with % Damage vs Demons? I hope you get lucky and get a 20% Damage vs Demons mod since they go for ridiculous prices. Good luck

The weapons mods seem to drop often in Cantha for me and as far as the shield mods, they do not exist but there are 2 Nightfall unique shields with that mod:
1. Aegis of Aaaaarrrrrrggghhh
2. Aegis of Terror
Can get them cheap these days 10-15k but you don't see them selling very often.

There do drop shields with +armor vs demons in factions. I have had 1 drop myself.

see thats the thing, ive been doing the Chos estate farm which of course is in Factions, im getting tons of non max blue vs demon mods(no armor+ vs demons yet) but its gotta be something to do with them not being insc...not to mention that there are Oni and such in factions even on noob isle. gott 19% sowrd pommel vs demons xD...but yeah. somethings just right about it, somone needs to help me test it doing Chos.
