Thanks for the great tutorial! It works like a charm. I did run across one small problem though.
When I try to give a henchman "Slow Current" from the Hydrosophist line, it doesn't show up in game. I've made sure it was spelled correctly (even copy/paste) but it just doesn't show up. All the other skills I've tried work but it doesn't seem to recognize "Target_SlowCurrent". It's not that big a deal but just thought I'd mention it and see if anyone else had the same problem or if it worked for them.
Got it! On a hunch I tried "Target_Slow" and it works. You may want to update your chart.
