Strangest thing...... well..... jump over 5 yards from the Stan or like over 3 yard upwards. Truly strangest thing. Totally unique... never been bevor in a DnD game. Basically froggers gate 3
Its in the jump rules for 5e and explained pretty well here, but I'm sure I can find info on the movement enhancing spells etc if you need. It's definitely been a thing in D&D over several editions however, I've been in parties where high dex characters have jumped several stories from a standing start.
