Way to make a specific tile unwalkable?

I am using a custom Outland_abyss. Because I needed to have squary cliffs and walls like dalaran Marble up one/two level(s), and Outland doesn't have them - it only has natural irregular rocky cliffs, I had to make my map in Dalaran tileset. In Dalaran there isn't a single tile that is unwalkable, unlike Outland. Only the water. I need to make the abyss replacing Dalaran Dirt unwalkable without using pathing blockers, Im not gonna spam the entire map in pathing blockers. Also without borders because they will darken what's in the abyss and I lose the effects like that.

Jass New Gen Pack has its own section (with UMSWE enabled) of making the tiles whatever you want. Go to "UMSWE" tab and then find "Customize Tile Pathability". Untick the "Walkable" for the tile and after you are finished, go to "UMSWE" tab again and tick "Custom Tile Pathability".
