Teleporing skeleton, eh? [s]*Undertale flashbacks*[/s]

That definitely sounds interesting! Something that teleports in shadows probably doesn't need too many legs, unless I'm misreading the messages. Does the monster stay in shadows, or does light not bother it? Is it really slow in terms of walking speed which makes teleportation necessary for mobility, or is it kindof just a thing it has? Does it pull a Reaper from Overwatch and is momentarily vulnerable while it teleports?

I have a lot of questions for this.
