I'm looking for some pointers on how best to position Primordius to maximize dps and limit mutations. We have been kiting in a circle just outside the middle ring and move him at a pretty quick pace but it feels like a lot more movement than I see in videos. Other than the slimes necessary for mutations how many shoułd we be killing? We seem to have very inconsistent dps on this fight and I'm just looking for ways to optimize.
For reference, he is usually at mutation level 7 around the 6 minute mark.
