If not a Rogue:
[Sun Aug 11 13:44:59 2019] You have no skill in the art of applying poisons.
Rogue:
[Sun Aug 11 13:57:24 2019] You must be sitting to apply the poison.
[Sun Aug 11 13:57:33 2019] You begin applying the poison.
[Sun Aug 11 13:57:43 2019] You have become better at Apply Poison! (3)
[Sun Aug 11 13:57:43 2019] You failed to apply the poison.
It no longer indictates that it is expendable upon inspection, but it is indeed single-use. Item disappears after applying (or failing to do so). Item is retained if you are not a rogue.
