Gnomish Gravity Well use-able everywhere in Grim Batol

[OmniBlink]

Nothing serious, but the Gnomish Gravity Well is use-able everywhere inside Grim Batol.

It's relevant because of the Timewalking dungeons currently going on there.

Hypothetically, if your entire team used it, you could skip packs of the trash and parts of the instance entirely.

It's also great for exploration, as the walls and everything above the floor where you stand is hollow and you can go right through it all.
