Coldain shawl 6 without losing SG faction
 

Can I kill the sirens outside the grotto in the zone cobalt scar to get the item? do they reduce faction or is it just mobs inside SG itself?

Just curious, why do you care about SG faction; I thought everyone was KOS?

But to answer your question, as the wiki helpfully shows, Siren's Hair also drops off of the sirens in Cobalt Scar, who don't (at least according to the wiki) hurt SG faction. Watch out for their charm though ;)

You will inevitably have to go into SG for Shawl 7, at least for the Swordfish Tooth, and possibly also for the Molkor Hide and Runed Sea Shell ... but the Swordfish Tooth comes from fish who shouldn't (again, according to the wiki, which could be wrong) hurt your SG faction, and the other two are droppable so you can buy them off of other players.

If you don't kill a single mob the faction is high enough to get dubious with the velium faction necklace

Fishies very much hurt SG faction. :3

it drops in cobalt scar, wiki is self contradictory on hurting siren faction, I can't find it in my logs halp nerds(Ctrl+F 'Siren Hair')

got two hairs this morning in CS, and can confirm that killing the sirens there definitely hurts SG faction.

Thanks for testing it for me!
Glad I didn't fall for the trap, I'm shure the wiki was written by my enemies on the red server conspiring to destroy my position.

Why don’t yo just buy it, don’t you have like 40 bill?

Sounds like the wiki needs to be updated. Do either of those guys give any other faction besides just negative Sirens of the Grotto?

the sirens were just negative to grotto.
