Athlete's Ally

FEAT 14
Activity 1 action

Requirements You're wielding your warshard weapon.

You channel the power of your warshard through your weapon to better perform athletic maneuvers. Spend a Mythic Point. For 1 minute, when you attempt Athletics checks to Disarm, Grapple, Reposition, Shove, or Trip with your warshard weapon, you do so at mythic proficiency. Note that this ability doesn't grant additional weapon traits to your weapon, so your options for which of these maneuvers you can attempt might be limited by your weapon's existing traits.
