Speak with one of the followers of Skalmos in Freeport. For this, you first need to use the Troll illusion that was given to you.
Once applied, go to ( -53, -24, -21 ) /waypoint -53.40, -24.43, -21.29 and speak with Velt.
Velt asks you to collect 6 Words of Zxrath from around Freeport. These are shinies (edit: They are technically NOT shinies, as shinies are a specific type of harvestable. The harvestables in question are animated/flapping pages with white sparkles. // Catya, Halls of Fate, 20th of June 2017) throughout Freeport. They spawn locations seem to vary from time to time, so if you do not find a page at a location cited below, try exploring in the vicinity. Known locations:
Last one I found was in the Freeport Militia House.
Return to Velt.
He will tell you to head back to Big Bend. Go there and speak with Velt at ( -27, -5, 74 ) /waypoint -27.40, -4.67, 74.20 Have your troll illusion still on.
Take the offering to Skalmos in Big Bend ( -26.89, -4.66, 89.39 ) Copy and click on the table. This will spawn Skalmos.
He will talk a little, then you will be attacked by a couple non heroics.
