D&D 40th Anniversary Blog Hop Challenge Day 5

First character to go from 1st level to highest level possible in a given edition or what's the highest level character you've ever ran?  Quincy Vanderbeak III, a rogue in Tony W.'s DnD Next Kit Bash game.  He's 7th level now and we've been playing close to a year.  He's the face of the group and keep's the severed heads of his victims in his Bag of Holding (they've come in handy while fighting zombies).  Our group are grade A assholes, we like to overthrow towns for fun and profit.
