Secondary recall seems to work when you use a marking stone, but then binding somewhere else sets your secondary bind to that spot as well. I was able to use secondary recall successfully right after using the marking stone, but the next time I tried after changing my normal bind point, it took me to my normal bind point instead of the spot I marked with the stone. Also, even if it's working, a trip to PoK and 100p to get a stone of marking seems like more hassle than it needs to be; any chance of getting it put on a THF vendor and maybe having the price reduced and/or made stackable?
(edit) Actually I played with it more and the marking stone sets both regular and secondary bind, as does bind affinity.
Thanks,
