If you're gonna focus on charge and cheese is not a worry then there is always the "Giant" Gecko. Ceiling, and walls are now available for charges or you could just give your wolf lots of spider climb potions.
yes I use Hero Labs and only have PDFs. The option of leveling up on paper and then making the hard adjustments on HL when I have net access is a solid one. I was also under the impression that pre-leveling was just as bad since you don't know that you will get credit for each game. The HL app for the IPAD does not allow leveling up currently though that would certainly solve this issue if they did. I do have paper copies of my character that I use at the table as well as the digital ones. The App has its advantages as a tool as well as the paper sheet.
If I play a full day (or weekend) at a Con and my character gains enough XP in the middle of the Con to level up but I do not have a way to level him up as my Laptop is not available do I have to stop playing him until I can get him lveled up or can I level him up when I get back home?
