the Drossheart hirelings do look really cool, love the outfits they are wearing and the mask
yes, targeting is a bit wonky on the bottles, sometimes it just stands there throwing at the wall, or the floor when nothing is there, sometimes hits the ceiling (hitting the ceiling was targeting issue, the curve too high, originally with the class if I remember correctly)
the melt lock is hard to get them to do, often says 'lock in use' but nothing happening, hireling says ok, or sure, but does not do it, took them both into stormreaver fresco and it was very hard to get them to open stuff, if at all. Tried both the lvl 8 and 32 in there, same reactions.
close range or distance, both needs a bit of work, altho close range that is 'clear of obstacles' the targeting seemed ok.
I found using hot bar sometimes targets better, sometimes not lol. Hope it all gets tweaked, is interesting hireling indeed.
