Thanks both. Ended up just selling the dex/qd charm to someone interested.
I know its not really written anywhere, but in your experience is it just the final hit or does spawning them with ML matter to? Not really practical to be switching charms all the time for that.
From the consensus over the years with ML gear, a majority of players have mentioned that it works on final hit, hence switching. There are some, including myself that think it is based on wearing it when monster spawns, I personally would test this with Welling, put the ML gear on, drop the white item into the Well, then switch to killing gear and then switch back to ML gear before killing it off... as for an outcome to it working... nothing good dropped (in my assessment because I can not go back in time and see what would have dropped without doing above.)
It is player choice really ... some people use ML gear and slog it out in a climb (solo), others don't and use it on final hit
(which makes sense with RNG and % chance of drops based on the Killing Blow and not previous requirements.)There is one fact though... Transmuting and using ML gear does work and is more obvious then monster killing. And you don't have to switch out gear... awesome right.
