Sea Hag
The Sea Hag is an enemy in Tomb Raider V in the level Old Mill. It appears underwater, protecting a silver coin that sits at the bottom. If Lara gets too close, a cut scene will be triggered, showing Lara struggling to get away from the creature. Occasionally the Sea Hag will follow Lara, and if the creature gets too close, it'll make a lot of damage.
The cut scene will keep on playing until Lara will get the item. Lara must wait until the Sea Hag gets further away, pick up the coin and swim away before it comes back.
The coin is then used to at a cage in the bottom of the same lake. The Sea Hag swims to the cage, lured by the coin. Lara traps the creature isnside, and the cage is then pulled up by the little demons. Apparently the demons then eat the Sea Hag.
