Either the tooltip for Soul Drinker is incorrect or the function of it is not working. I chose this thinking I’d get either 1 more Skeleton Archer (SA)/Skeleton Mage (SM) of my choice or 1 of each. But, currently when selecting it I can summon 1 more SA, but not SM. I tried removing the SA skill from my action bar thinking maybe it was a 1 or the other for SA/SM but still cannot get another mage. So either the tooltip should read +1 to SA or fixed to do either/both.
I realize the tooltip says affects “Summon Skeleton” skill now. My bad, can ignore this now
