Possible Way to Explore Fortress of Jahai

On very, VERY brief occasions, an enemy will spawn on top of the stairs behind the gate (this has happened to me in one of the Pogahn Passage mission cages). Now, if you were to take a necromancer teleport skill, kill the enemy that spawned incorrectly, and teleport to their corpse, would it be possible to explore the remainder of the fortress?
I do not recommend you try this for yourself, as the chances of an enemy spawning incorrectly and in the right spot is very meager. But I have seen it for myself so I know that it would probably be possible to teleport to its corpse.
*Forgot to add that this is the Jahai Bluffs side of the Fortress

It might be possible, normally you can't teleport vertically, and I've no time to test it out, but it's plausible.

I believe Necrotic Traversal can help you achieve this without a doubt at all. Of course he needs to be killed first and his corpse needs to be in your aggro bubble.
