So, this came up in a game discussion: Mercury's Winged Sandals, from Transforming Mythic Europe (pg. 111). The description says that you can have up to Encumbrance/Load of 5, although it will slow you down. No problem.
However, page 107 discusses using Rego spells and requisites to carry things. It says that you'll need a requisite for the effect if your encumbrance is greater than medium (3).
So...which is it? The rules for the sandals seem fine enough, in that they're graded for how much stuff you have on you. And I suppose if you want to be technical, the guidelines on pg. 107 are for INSTANT transportation. Is this some change in the rules for flight, rather than teleportation?
(Also, how long is a turn? I thought 50 paces/turn = 17 miles an hour, on the assumption that a turn was 6 seconds. If it was 3 seconds, that "40 miles an hour" would make more sense.)
EDIT - OK, looks like a lot of the "flight" in that section of TME is a variation of levitation, rather than a straight cross-over from the Teleporatation version. As such, they are defining "move a target quickly in any direction they please" as "around 40 miles per hour". Is there any basis for that number? I don't mind, but it seems slightly arbitrary. But I guess the guidelines for teleportation are different than the flight/levitation guidelines?
