((Kinda eating crow here... I wasn't definitive... https://forum.atlas-games.com/t/table-talk-bibracte/6080/1331. I can see it going either way, and I'm willing to roll with it being allowed and possible, my reason for suggesting it isn't possible is outlined above, but I like that reason less and less and doesn't make a whole lot of sense. If you can't Leap away from spells like PoF, BoAF and IoL that becomes problematic. Plus, sometimes Leaping is the wrong choice. For the Dimicatio, though, the audience doesn't like Wizard's Leap, the first round of 32 is fine. In the subsequent rounds, it's not a well-liked defense, but we will say it is legit. You just can't use it as was described in Table Talk, to leap behind a competitor, as the field of competition is bounded. Going out of bounds would be a DQ. If Roberto wants to win with Leaping, it's certainly possible, but comments of bad form will be made.))
