assassination prepare

[Kage]

Deep within the dead moors
  Everything is black here. Ghostly lights flicker paley about your feet and
cast foreboding shadows amongst a variety of twisted and rotting
plants. From nearby a flare of light briefly lights up the darkness, but
quickly fades to nothing.

[Exits: south west]

SW> aprepare
You can't prepare for the kill here.

SW> aprepare
You are unsure of the best place to begin your preparations.

- Just to clarify this is a beast Assassin in wyvern stance attempting to aprepare.

Two things. 1.) Why can't I prepare here?
                   2.)  Second try to aprepare looks like a failed attempt since skill is not mastered.   This may be possibly abusable to spam and master assassinate with no lag.

[Kiri-Jolith]

You cannot assassinate in Swamp.
There is no way to abuse.
