For pretty much every AoM pet, the skill summons the pet where your cursor is. If you click the skill in your toolbar, you have to then click in a specific location to summon them. If you use a hotkey, it is summoned where your cursor was.
I remember reading once that the mechanic was sort of experimental so I’d like to provide my feedback on that: I hate it. It frequently causes me to not summon things when I try to because my cursor was at an invalid location, and given the pace of the game and how long most pet summoning animations take, you can’t reliably put them in a useful position anyway because by the pet is able to act everything has moved and the position is no longer be useful.
