quick question

how do I make it so when you step on a circle of power, you get a certain hero? I need to have it like a hero arena, but noone else will be able to select the hero after you. I also need to teleport the hero to a different area of the map.

Do this trigger:
Event-Unit - A unit enters Blademaster select <gen>(unit enters region event)
Condition-(Unit-type of (Triggering unit)) Equal to Your Unit
Action-Unit - Create 1 Blademaster for (Owner of (Triggering unit)) at (Center of (the region that the hero should be created)) facing Default building facing degrees
Unit - Remove (Triggering unit) from the game
Unit - Remove (Select the Hero unit that was on the circle of power) from the game
Unit - Remove (Select the circle of power) from the game
Trigger - Turn off (This trigger)
This selects the hero, transport it and whipes the selction from reallity, making no one else to even know that there was an hero there.
