Teemo Glitch
Sometimes the poison from e will kick in at level 1 when I use the q first. Has happened a few times while attacking the blue buff leashing the jungle player, and once in lane against a riven. I had q at level one and used the invisibility passive. I think that had something to do with it being invisible in the bush.
Sorry it took so long to say anything I forgot to when it happen and remembered tonight so I thought I would drop the note.
