[@Lugubrious] I have a couple ideas

[i]Broker[/i]
An epithet that allows the user to "buy" and "sell" other epithets. Essentially, they can temporarily steal another epithet, but the catch is they can only hold one at a time and must return the current epithet to its owner before snagging another. They can also temporarily switch the epithets of other people.

[i]Byway[/i]
The user isn't forced to use any of the "main roads" of life. This grants the user the ability to create  various types of spacial byways including linked portals that allow travel between them and static portals that go straight through solid objects.

You're on the right track, with Byway especially, creating shortcuts around and even through obstacles and offering escapes where others would be stuck. Your idea for Broker might be a bit overstated, especially since buying and selling involves trade and not just giving or taking. Maybe it makes for a good support epithet, allowing him to sell temporary epithet or ability power-ups so long as others pay him, and if they can't or won't he can temporarily take some of their power to use or trade with. He could also spend his assets to debuff others. That way, it's more like buying and selling than stealing and swapping.
