Echo Location

Echo location – You can expend a bonus action to have your echo use echo location. Any enemy (including those who are invisible) within a 60 feet radius will be known to your echo and your echo will be able to reveal them to you. On your next turn you may use an action to light them up in any colour of your choosing, but visible to your team, for 1d8 rounds granting your allies advantage on their attack rolls against them while lit, but expending your echo. You cannot summon another echo this combat.
