Changeling ability: Lurk

[Frank_Stein]

I'd be cool with this if they could only do it while in Abomination Form. Maybe also make it so they can pull someone down into the floor with them if they step on the same tile, like an antlion.

While we're talking about Changeling abilities, does anyone else think headspider should be changed/removed? I haven't seen one actually take over someone in forever, since everyone knows about it and will either take care of it, or just kill themselves before the change out of spite.
