Just been poking a leet in agartha in tank build with hammer/chaos, using Sanity’s Aphelion as the offhand.
The strange thing was that normally you wouldn’t expect the Sanity’s Aphelion to proc when you’re just using the hammer basic to attack, but I was regularly getting the Extradimensional Defender spawning. At no point was I using the chaos focus, it remained inactive in my offhand at all times, but the E.Defender was still spawning.
Aegis of Parallelism was also proccing and delaying damage, also with no offhand chaos focus use. Not sure if that part’s intended, but it was a surprise to see the defender spawn!
