I have been playing this game for almost two weeks everyday, and have been enjoying immensely. I have one question, it appears to me that most of the movement cards come from boots and what was initially in the beginning "deck". I have had some adventures where I have not been drawing any movement cards. Are there items, or ways to get more movement cards? I may not be setting my deck well, but I was just wondering? Other than that, I love the game. I am thinking about "joining" to see what else I can pick up. Keep up the great work.
There are some shields that have movement cards, also some from racials, and there are the occasional teleports and electroports on arcane items, skills, chests and even helmets (if I'm not misstaken). The most reliable source would be boots as you've correctly identified and possibly racials (especially for elves).
There's also a lot of dual cards that provide movement options as the second half. Some people miss these. For instance any Dodge you have can also be used for movement. This is a really good way to get additional movement without limiting your options.
Don't forget you can equip teammates with cards that will help others move. Things like Dash, Team!, and my wizards occasionally find an excuse to cast Telekinesis on allies to move them further. Cards like these will also ignore Encumber and Halt effects, too. Pretty useful!
