Echolocation. The ekimmara can't use its blindsight while deafened.   Keen Hearing. The ekimmara has advantage on Wisdom (Perception) checks that rely on hearing.   Sunlight Sensitivity. While in sunlight, the ekimmara has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight.   Undead Fortitude. If damage reduces the ekimmara to 0 hit points, it must make a Constitution saving throw with a DC of 5 + the damage taken, unless the damage is radiant, fire, or from a critical hit. On a success, the ekimmara drops to 1 hit point instead.   Spider Climb. The ekimmara can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.   Turn Resistance. The ekimmara has advantage on saving throws against any effect that turns undead.   Regeneration. The ekimmara regains 20 hit points at the start of its turn.

The ekimmara dies only if it starts its turn with 0 hit points and doesn't regenerate.   Blood Frenzy. The ekimmara has advantage on melee attack rolls against any creature that doesn't have all its hit points.
