Ekhidnas - The Witcher 3 Guide - IGN

Ekhidnas are the more advanced form of the Siren in The Witcher 3: Wild Hunt . They are just as deadly in the water as they are in the air. Their attacks can leave you momentarily disoriented and they often fight in packs. One wrong move could be fatal when you take on these monsters.

Found throughout Skellige, they inhabit shipwrecks, remote islands, and the mountaintops. When hunting ekhidnas for their drops, you'll want to stay away from water locations. While you can kill the creatures underwater or in the air with your crossbow, you won't be able to loot the corpses. Stick to the mountains or areas along the coast of Ard Skellig.

Ekhidna are found along Skellige's coast, specifically north of Arinbjorn towards Eldberg isle. They can spawn from Siren nests when destroyed, including the wrecked ship monster nest to the north of where you crash on Ard Skellig. One is located at the Guarded Treasure southeast of Kaer Muire and at the Elverum Lighthouse in the southwest of Ard Skellig. You'll find a group of them on the western coast of Faroe Island in Skellige. In the mountains, head to the Trail of Yngvar's Fang where they are located near the start of the trial. Melusine herself is encountered during the side quest Contract: Here Comes the Groom .

Like other flying creatures, landing a crossbow shot or hitting it with Aard will bring the target crashing to the ground where it is weakened. You can also burn it with Igni right when it swoops towards you, causing the monster to fumble to land as well as inflicting damage over time. If they land farther away, use a Grapeshot bomb for ranged damage as you close the distance. Then deal the fatal blows with your silver sword coated in Hybrid Oil .

Ekhidnas have a chance to drop a blue mutagen that's used as an ingredient in the Ekhidna Decoction . When equipped in a skill tree it enhances Sign intensity by 5%, scaling up to 20%.
