I love the idea of the portal character but I've linked another hero concept posted in here (Mirror traveler) and I think this character and mirrors fit so much more in the setting I feel but with the mirrors as portal. I think that character design and your kit would fit great together.
I think both hero ideas are cool regardless of my opinion

Ok, hero might be experemental, i tried to play the gameloop in my head so it would be kind of OP and kind on not OP at the same time, so not sure if all the kit works well without oversights. I wanted a hero which can go into the mirrored world though mirrors, should be played stealthy/ganky. 1st ability has the griefing potential, but i dont think it should cause too much problem, with some tweaks and changes maybe itll be more balanced but not making hero too conplicated inline with other hero designs. For the ulty there were many ideas but i stuck with this, and thought it...
