100% Safe (exploit) way to kill Cursed Dragon on Duskmoon Tower

While farming i found out about this "pillar-stuck-glitch" where the Cursed Dragon just can't reach you.
Recommended level is 60+.
So this is a cheap way of killing him.
You need to have ranged/magic attacks for the 100% safe results.
Using Holy based skills works wonders.
You need Rancid Bait Meat for the dragon to appear.
You can do solo as well, doesn't matter.
I'm getting 1-2 level per kill on level 70+ on Hard mode.

This is my first guide, i'm sorry if it's not as good as could be, i'm sorry if this information is already old/knowed, i just found out about it and since there was no guide talking about it, i made this one.

This is where you should stay on the map and where the Cursed Dragon won't reach.
Get on that corner before you put the Rancid Bait Meat down, so when the dragon shows up he'll run right into the space between the corner and the wall:

Here's the view that you'll have on that corner:
This is the view from outside the corner (Where the dragon will get stuck):

I'm using my MK with Blessed Trance to Cannon the hell out of it.
Here's some screenshots:

You just have to watch out for his spit move, easy to avoid, just get behind the pillar, he can't reach you either way.
Here`s where to hide from the spits.

Eventually they die, because well... AI.
You can just wait for the dragon to fly up, then when he falls back down, you can run and ressurrect:
