Nimble Moves (Mythic)
You dance across obstacles with ease, as though they weren’t even there.
Prerequisite: Nimble Moves.
Benefit: For every 2 tiers you possess, you can move through up to 5 feet of difficult terrain each round as if it were normal terrain (minimum 5 feet). This effect stacks with those provided by Nimble Moves and Acrobatic Steps.
