Normally I'd demand out from you to at least justify how the skill was gained or spend some time practising it. But since it is a PBF, I allow that illogical computer game xp-spending model, when you spend shiny points to pull your skills right from the sleeve, so expect wonders like people learning how to read in a second or grabbing a gun they have never shot before and pulling a headshot right away...
I'll try to post in a while, answering several of your PCs' questions and describing the rosette a bit more. Thanks for the effort, Lucky! Sometimes I need to be reminded to make more complex describing, because this is the part I often forget.
