10d is the maximum size for any dicepool, yes.  The system works by rolling a number of d10s equal to your dicepool and looking for matching sets, so it becomes mathematically impossible to fail when you have more than 10 dice to roll.  As for how the table works...<br/><br/>Well, let's take Zenobia's Sturdy Wings as an example.  At 4d, they give her a normal travel speed of 16mph, and with their Useful [Carry someone else] ability, they can carry up to 400 lbs of 'someone else', enough for a good two or three people.<br/><br/>The Monster Might Table is mostly only for when you need to adjudicate things like carrying capacity, travel speed, and so on, though.  Most of the time, these numbers won't actually matter all that much.<br/><br/>To bring up another example, you remember that 'Orgy of Succubi' monster that I statted up in the interest thread, and how that monster's 'Assorted Naughty Bits' part had a 'Useful [can pull a variety of handy items from places best left unmentioned]' ability?  That body part was also at 4d, so the Orgy of Succubi could pull an item weighing up to 400 lbs from out of a place best left unmentioned.  That's literally getting up to the size of smaller and lighter motorcycles, which...  Yeah, just don't think about it too hard. >>; Suffice it to say, monsters can get pretty monstrous, depending on the numbers.
