Im fairly new to this game and working hard to get all the rules down before I start bringing players in, and I am a bit confused about exactly what effects can occur from an aspect placed by a maneuver.  It seems that the standard is a one time +2 bonus that the character who applied the maneuver can use or pass off for a limited time, depending on how well the maneuver landed.  There are hints that other things might be possible.  Specifically, the Venomous Claws ability adds Poisoned which makes continued attacks until the victim concedes or is taken out, and there is a paragraph about special weapon effects existing near the end of the book.  It seems like this sort of effect would have a lot of uses, from Molotov cocktails to entropy curses, but Im not seeing much in the way of rules or examples for these sorts of aspects. 

Are there any rules that Im missing here, or would making alternate effect aspects have to be a homebrew project?
